The tests serve as an important exercise for the three U.S. Meteorological Watch Offices (MWO) in Kansas City, Anchorage and Honolulu. The tests will include all three types of SIGMETs: Volcanic Ash (VA), Tropical Cyclone (WC) and Weather phenomena (WS). The validity period will be 10 minutes. The three MWOs will coordinate with the Volcanic Ash Advisory Centers (VAAC) in Anchorage and Washington for the Volcanic Ash SIGMETs and with the Tropical Cyclone Advisory Centers (TCAC) in Miami and Honolulu for Tropical SIGMET issuance. The schedule is as follows: On November 10, 2010, the SIGMET test for Tropical Cyclone (WC) is scheduled to occur at 0200 UTC, when the Miami and Honolulu TCACs issue their Tropical Cyclone test advisories that drive the SIGMETs produced at the Kansas City and Honolulu MWOs. The following two WMO IDs will be using during this test: WCPN## KKCI WCPA## PHFO On November 17, 2010, the SIGMET test for Volcanic Ash (WV) is scheduled to occur at 0200 UTC when the Washington and Anchorage VAACs issue their Volcanic Ash Advisories (VAA), which drive the SIGMETs produced at the Kansas City, Honolulu and Anchorage MWOs. Look for the following three WMO IDs during this test: WVAK## PAWU WVPN## KKCI WVPA## PHFO On November 24, 2010, the SIGMET test for Weather phenomena (WS) is scheduled to occur at 0200 UTC when the three U.S. MWOs issue their test SIGMETs.

LOCAL 4 AM-TO-4 AM. THIS CONDITION EXISTED FROM APRIL 2009 UNTIL MID-OCTOBER 2009. WHILE CORRECTING THIS ISSUE... THE OPPORTUNITY WAS TAKEN TO MAKE SEVERAL OTHER TECHNICAL CORRECTIONS AND IMPROVEMENTS. TECHNICAL CORRECTIONS: - TIME FRAME USED TO LOOK FOR STATION UPDATES WAS ALSO CORRECTED. TECHNICAL IMPROVEMENTS: - TRANSMISSION ROWS ARE NOW ORDERED ACCORDING TO STATION WBAN NUMBER DESIGNATIONS. THIS MAKES MANUALLY LOCATING A PARTICULAR STATION IN AN UPDATE FILE EASIER. - TRANSMISSIONS OMIT STATIONS THAT ARE NOT ACTIVE. THIS PREVENTS ROWS OF MISSING VALUES FROM BEING DISPLAYED FOR STATIONS WHICH ARE NOT ON RECORD. STATIONS THAT ARE ON RECORD BUT HAVE NOT PROVIDED ENOUGH OBSERVATIONS TO CALCULATE DAILY VALUES WILL CONTINUE TO BE REPRESENTED BY MISSING VALUE INDICATORS. - TRANSMISSIONS ARE RESTRICTED TO THE TWO MOST RECENT DAYS TO AVOID OVERLOADING USERS WITH OLDER UPDATES BEST FOUND BY DOWNLOADING STATION-YEAR FILES THROUGH FTP.

This will be a multi-grid hurricane wave model and will replace the existing North Atlantic Hurricane (NAH) and North Pacific Hurricane (NPH) wave models. The model upgrade will result in a change of 27 minutes to the product dissemination time and the generation of new products. Details of these changes are outlined below. Model Changes: Instead of two separate models, the hurricane wave model will now be a single model with multiple two-way nested grids. The new multi-grid hurricane wave model will use WAVEWATCH-III v3.14, which is the same model version as NCEP’s Global Multi-grid Wave Model (the current NAH and NPH use WAVEWATCH-III v 2.22). The upgrade to version 3.14 will result in the following: - Upgraded shallow water physics, which accounts for shallow water processes such as wave breaking. Together with the increased wave resolution in coastal regions, this change will provide a better representation of wave physics in land falling hurricanes. - Increasing internal model spectral resolution to 50 components in frequency and 36 components in direction. Spectral output at the points will continue to be 29 components in frequency and 24 components in direction. - Adding a new algorithm to partition the spectral energy into wind wave, primary and secondary swells. Spectral parameters for these different fields (wave height, peak period and direction) will be part of the model output on the new grids listed below. These fields will not be added to the existing NAH and NPH products. Wind forcing for the global, Alaskan and Pacific Island grids will be from the Global Forecast System (GFS) winds while all the other grids will be a blend of the GFS and GFDL hurricane model winds, as is currently done in the NAH and NPH. The only exception is the Hawaiian Islands, part of the Pacific Island grid, which also will have a blend of GFS and GFDL hurricane model wind forcings. Product Changes As a result of this upgrade, all of the output products from the new multi-grid hurricane model will be disseminated 27 minutes later than the current NAH and NPH output products. Any concerns with this change in product dissemination time should be directed to the contact points listed below. The output grids from the multi-grid hurricane wave model will be as follows: Products with 25x24 spectral resolution: -Current 0.25 degree NAH grids -Current 0.25 degree NPH grids Products with 50x36 spectral resolution: -New 0.5 degree global domain grid -New 0.25 degree regional domain for North Atlantic (domain corresponds to current NAH grid) -New 0.25 degree regional domain for North Pacific (domain corresponds to current NPH grid) -New 10 arc min grid for the North Atlantic regional waters -New 10 arc min grid for the North Pacific regional waters -New 10 arc min grid for the Pacific Islands and Hawaii -New 10x15 arc min grid for the Alaskan waters -New 4 arc min grid for the US East Coast -New 4 arc min grid for the US West Coast (including the coastal waters of Hawaii) -New 8x4 arc min grid for the Alaskan coast NCEP will continue to produce the current NAH and NPH output products, including their respective point output files, until further notice. These products will be generated using output from the new multi-grid hurricane wave model. The new grids will be disseminated via the NCEP server and will be incorporated into AWIPS on a yet-to-be-determined date. More details about the NCEP Multi-grid Hurricane Wave Model are available at: http://polar.ncep.noaa.gov/waves/index2.shtml A consistent parallel feed of data will become available on the NCEP server once the model is running in parallel on the NCEP Central Computing System, around September 7, 2010.

All components of the CFS-- the atmospheric model, ocean model, land-surface model, and data assimilation--will be upgraded as part of this change. Please note that the current operational CFS version will be discontinued on January 18, 2011, and THERE WILL BE NO OVERLAP PERIOD after the upgrade is implemented on this date. Users must upgrade their process of obtaining CFS data, as there will be major changes in content, format, volume of data, and data dissemination source with this upgrade. A 3-layer interactive global sea ice model, as well as global land data assimilation will be introduced to the CFS. The resolution of the atmospheric forecast model will be increased from T62 (210 km) to T126 (100 km). The ocean forecast model will be upgraded from the limited area GFDL MOM3 to the global MOM4. The horizontal resolution will increase from 0.33 degree to 0.25 degree from 10 North to 10 South latitudes. Northwards and southwards to the poles, the resolution will increase from 1 degree to 0.5 degree globally. The land surface model will be upgraded from the 2-level OSU Model to the 4-level NOAH land model. For more details on the upgrades to the forecast model and products, please check the CFS website at: http://cfs.ncep.noaa.gov/cfsv2.info The data assimilation for the Climate Forecast Model will also be upgraded. The resolution of the Atmospheric Climate Data Assimilation Version 2 (CDAS2) will be upgraded from T62 (210 km) with 28 sigma levels to T574 (27km) with 64 hybrid sigma- pressure levels. The Spectral Statistical Interpolation Scheme (SSI) will change to a Gridpoint Statistical Interpolation Scheme (GSI). Satellite radiances will be directly assimilated instead of retrievals. The Global Ocean Data Assimilation (GODAS) also will be upgraded from MOM3 to MOM4. In addition, there will be a new Global Land Data Assimilation (GLDAS) which will use observed Climate Prediction Center (CPC) precipitation as forcing for the NOAH land model. For more details on the upgrades to the data assimilation and products, please check the CFS website at: http://cfs.ncep.noaa.gov/cfsv2.info There will be significant additions to parameters in the pressure grib (PGRB), flux files (FLX) and ocean (OCN) files. In addition, there will be a new file that contains parameters on isentropic surfaces (IPV). Due to the increases in resolution, there will be significant changes to the format, content and sizes of all these files. The horizontal resolution of PGRB files will increase from 2.5 x 2.5 degree to 1 x 1 degree and the number of pressure levels will increase from 17 to 37. The size of the flux file will increase from the Gaussian grid for T62 (192X94) to that for T126 (384X190). The ocean file will increase from 2.5 x 2.5 degree to 0.5 x 0.5 degree. The new isentropic file will have a resolution of 1 x 1 degree. There will also be an increase in the temporal resolution of the output forecast data from 12-hourly to 6-hourly. For more detailed information about changes and additions to these files, please check the CFS website at: http://cfs.ncep.noaa.gov/cfsv2.info All seasonal products will be discontinued, both for the real time forecasts and climatologies. Only monthly mean products will be disseminated. A set of test data is available at the CFS website: http://cfs.ncep.noaa.gov/cfsv2.info The current CFS output is disseminated via both the NWS FTP server and the NCEP server. With this upgrade, there will no longer be CFS output disseminated from the NWS FTP server at: ftp://tgftp.nws.noaa.gov/SL.us008001/ST.opnl/ in the MT.cfs_MR.clim or MT.cfs_MR.fcst directories. All CFS output, along with the climatologies, will be available only on the NCEP server and NOMADS. Beginning on January 18, 2011, CFS output from the current day will be available via http and ftp: http://www.ftp.ncep.noaa.gov/data/nccf/com/cfs/prod and ftp://ftp.ncep.noaa.gov/pub/data/nccf/com/cfs/prod CFS output from the previous 7 days will be available on NOMADS: http://nomads.ncep.noaa.gov/pub/data/nccf/com/cfs Data delivery timing of the CFS will be changed by this implementation. The new CFS will run longer than the current CFS and therefore disseminate the products at a later time. A consistent parallel feed of data will be available on the NCEP server by early December at the following URL: http://www.ftp.ncep.noaa.gov/data/nccf/com/cfs/para and ftp://ftp.ncep.noaa.gov/pub/data/nccf/com/cfs/para Users should ensure their decoders are flexible and able to adequately handle changes in content, changes in the scaling factor component within the product definition section (PDS) of the GRIB files and any volume changes which may occur.

Geographic coverage is the 6km NDFD grid (grid 198), which covers all of Alaska 2. Products will be in GRIB2 format 3. Output produced four times per day (0000, 0600, 1200, and 1800 UTC) 4. Output available every 6 hours out to 384 hours 5. Output available for eight variables: surface pressure 2-meter temperature 2-meter maximum temperature 2-meter minimum temperature 10-meter u-wind 10-meter v-wind 10-meter wind speed 10-meter wind direction 6. Ensemble products for each of the 8 variables listed above include: 10% probability forecast (filename ge10pt) 50% probability forecast (filename ge50pt) 90% probability forecast (filename ge90pt) Ensemble mean forecast (filename geavg) Ensemble mode forecast (filename gemode) Ensemble spread forecast (filename gesprd) Test data is currently available at: ftp://ftp.emc.ncep.noaa.gov/gc_wmb/yzhu/alaska_q4fy2010/ Specific information regarding the GEFS/NAEFS model and associated products can be found at: http://www.emc.ncep.noaa.gov/gmb/yzhu/html/imp/201004_imp.html A consistent parallel feed of data will become available on the NCEP server once the model is running in parallel on the NCEP Central Computing System by mid-October. The parallel data will be available via the following URLs: http://www.ftp.ncep.noaa.gov/data/nccf/com/gens/para ftp://ftp.ncep.noaa.gov/pub/data/nccf/com/gens/para The products will be available in the ndgd_gb2 directories under gefs and naefs. The files will have alaska in the filename. After the implementation, the operational products will be available on the same server but the URLs above will end in "prod" rather than "para." NCEP encourages all users to ensure their decoders are flexible and are able to adequately handle changes in content order, changes in the scaling factor component within the product definition section (PDS) of the GRIB files, and also any volume changes which may be forthcoming. These elements may change with future NCEP model implementations. NCEP will make every attempt to alert users to these changes prior to any implementations.

Effective Tuesday January 18, 2011, beginning with the 1200 Coordinated Universal Time (UTC) run, the National Centers for Environmental Prediction (NCEP) will upgrade the Climate Forecast System (CFS). All components of the CFS-- the atmospheric model, ocean model, land-surface model, and data assimilation--will be upgraded as part of this change. Please note that the current operational CFS version will be discontinued on January 18, 2011, and THERE WILL BE NO OVERLAP PERIOD after the upgrade is implemented on this date. Users must upgrade their process of obtaining CFS data, as there will be major changes in content, format, volume of data, and data dissemination source with this upgrade. A 3-layer interactive global sea ice model, as well as global land data assimilation will be introduced to the CFS. The resolution of the atmospheric forecast model will be increased from T62 (210 km) to T126 (100 km). The ocean forecast model will be upgraded from the limited area GFDL MOM3 to the global MOM4. The horizontal resolution will increase from 0.33 degree to 0.25 degree from 10 North to 10 South latitudes. Northwards and southwards to the poles, the resolution will increase from 1 degree to 0.5 degree globally. The land surface model will be upgraded from the 2-level OSU Model to the 4-level NOAH land model. For more details on the upgrades to the forecast model and products, please check the CFS website at: http://cfs.ncep.noaa.gov/cfsv2.info The data assimilation for the Climate Forecast Model will also be upgraded. The resolution of the Atmospheric Climate Data Assimilation Version 2 (CDAS2) will be upgraded from T62 (210 km) with 28 sigma levels to T574 (27km) with 64 hybrid sigma- pressure levels. The Spectral Statistical Interpolation Scheme (SSI) will change to a Gridpoint Statistical Interpolation Scheme (GSI). Satellite radiances will be directly assimilated instead of retrievals. The Global Ocean Data Assimilation (GODAS) also will be upgraded from MOM3 to MOM4. In addition, there will be a new Global Land Data Assimilation (GLDAS) which will use observed Climate Prediction Center (CPC) precipitation as forcing for the NOAH land model. For more details on the upgrades to the data assimilation and products, please check the CFS website at: http://cfs.ncep.noaa.gov/cfsv2.info There will be significant additions to parameters in the pressure grib (PGRB), flux files (FLX) and ocean (OCN) files. In addition, there will be a new file that contains parameters on isentropic surfaces (IPV). Due to the increases in resolution, there will be significant changes to the format, content and sizes of all these files. The horizontal resolution of PGRB files will increase from 2.5 x 2.5 degree to 1 x 1 degree and the number of pressure levels will increase from 17 to 37. The size of the flux file will increase from the Gaussian grid for T62 (192X94) to that for T126 (384X190). The ocean file will increase from 2.5 x 2.5 degree to 0.5 x 0.5 degree. The new isentropic file will have a resolution of 1 x 1 degree. There will also be an increase in the temporal resolution of the output forecast data from 12-hourly to 6-hourly. For more detailed information about changes and additions to these files, please check the CFS website at: http://cfs.ncep.noaa.gov/cfsv2.info All seasonal products will be discontinued, both for the real time forecasts and climatologies. Only monthly mean products will be disseminated. A set of test data is available at the CFS website: http://cfs.ncep.noaa.gov/cfsv2.info The current CFS output is disseminated via both the NWS FTP server and the NCEP server. With this upgrade, there will no longer be CFS output disseminated from the NWS FTP server at: ftp://tgftp.nws.noaa.gov/SL.us008001/ST.opnl/ in the MT.cfs_MR.clim or MT.cfs_MR.fcst directories. All CFS output, along with the climatologies, will be available only on the NCEP server and NOMADS. Beginning on January 18, 2011, CFS output from the current day will be available via http and ftp: http://www.ftp.ncep.noaa.gov/data/nccf/com/cfs/prod and ftp://ftp.ncep.noaa.gov/pub/data/nccf/com/cfs/prod CFS output from the previous 7 days will be available on NOMADS: http://nomads.ncep.noaa.gov/pub/data/nccf/com/cfs Data delivery timing of the CFS will be changed by this implementation. The new CFS will run longer than the current CFS and therefore disseminate the products at a later time. A consistent parallel feed of data will be available on the NCEP server by early December at the following URL: http://www.ftp.ncep.noaa.gov/data/nccf/com/cfs/para and ftp://ftp.ncep.noaa.gov/pub/data/nccf/com/cfs/para Users should ensure their decoders are flexible and able to adequately handle changes in content, changes in the scaling factor component within the product definition section (PDS) of the GRIB files and any volume changes which may occur.

The horizontal resolution will increase from 0.33 degree to 0.25 degree from 10 North to 10 South latitudes. Northwards and southwards to the poles, the resolution will increase from 1 degree to 0.5 degree globally. The land surface model will be upgraded from the 2-level OSU Model to the 4-level NOAH land model. For more details on the upgrades to the forecast model and products, please check the CFS website at: http://cfs.ncep.noaa.gov/cfsv2.info The data assimilation for the Climate Forecast Model will also be upgraded. The resolution of the Atmospheric Climate Data Assimilation Version 2 (CDAS2) will be upgraded from T62 (210 km) with 28 sigma levels to T574 (27km) with 64 hybrid sigma- pressure levels. The Spectral Statistical Interpolation Scheme (SSI) will change to a Gridpoint Statistical Interpolation Scheme (GSI). Satellite radiances will be directly assimilated instead of retrievals. The Global Ocean Data Assimilation (GODAS) will also be upgraded from MOM3 to MOM4. In addition, there will be a new Global Land Data Assimilation (GLDAS) which will use observed Climate Prediction Center (CPC) precipitation as forcing for the NOAH land model. For more details on the upgrades to the data assimilation and products, please check the CFS website at the link below. http://cfs.ncep.noaa.gov/cfsv2.info There will be significant additions to parameters in the pressure grib (PGRB), flux files (FLX) and ocean (OCN) files. In addition, there will be a new file that contains parameters on isentropic surfaces (IPV). Due to the increases in resolution, there will be significant changes to the format, content and sizes of all these files. The horizontal resolution of PGRB files will increase from 2.5 x 2.5 degree to 1 x 1 degree and the number of pressure levels will increase from 17 to 37. The size of the flux file will increase from the Gaussian grid for T62 (192X94) to that for T126 (384X190). The ocean file will increase from 2.5 x 2.5 degree to 0.5 x 0.5 degree. The new isentropic file will have a resolution of 1 x 1 degree. There will also be an increase in the temporal resolution of the output forecast data, from 12-hourly to 6-hourly. For more detailed information about changes/additions to these files, please check the CFS website at: http://cfs.ncep.noaa.gov/cfsv2.info Another significant change will be the discontinuance of all seasonal products, both for the real time forecasts and climatologies.

The upgrade includes: -Changes to the model components -Addition of a Guam domain run -Changes to the Puerto Rico grid domain -Addition of new products and a new output grid for Guam -Change to the directory location on the NCEP server These changes will not be implemented on NOAAPORT or the Advanced Weather Interactive Processing System (AWIPS) at this time. A separate TIN will be issued for the future activation of the HIRESW changes on AWIPS and NOAAPort. Model Changes: The HIRESW model will be updated from Weather Research and Forecasting (WRF) version 2.2 code to WRF version 3.2 code for both the Advanced Research WRF (ARW) and the Nonhydrostatic Mesoscale Model (NMM) members of the system. Both the ARW and NMM models will use better conserving moisture advection after this upgrade. Domain Changes: The Puerto Rico domain will be expanded by approximately 50% to provide full coverage to Hispaniola. A new domain will be added to run over Guam twice daily at 00 and 12 UTC. The model grid spacing will remain unchanged at 5.15 km for ARW and 4.0 km for NMM for all domains. With the addition of Guam, the revised run schedule will be: 00 UTC: East, Hawaii, Guam 06 UTC: West, Puerto Rico 12 UTC: East, Hawaii, Guam 18 UTC: Alaska, Puerto Rico These runs may be cancelled by hurricane model runs during the tropical season. New Products: BUFR-formatted point forecasts for select locations will become available with this implementation. The new gridded output fields that will become available for all domains are: Echo top height from simulated radar reflectivity Planetary Boundary Layer height (Richardson number based) Hourly max updraft helicity Hourly max updraft speed Hourly max downdraft speed Hourly max 10 m above ground level (AGL) wind speed Hourly max 1000 m AGL simulated radar reflectivity Hourly max/min 2 m AGL temperature Hourly max/min 2 m AGL relative humidity Ventilation rate Transport wind 80 m AGL wind, temperature, moisture, and pressure In addition, NCEP will generate a set of new high-resolution, hybrid ensemble output that combines uncertainty information from the Short Range Ensemble Forecast (SREF) with deterministic forecasts from the HIRES. Output products from this HIRES ensemble will include mean, spread, and probabilistic guidance. Data Availability: The HIRESW data is currently available on the NWS FTP server, the NCEP server, and in NOMADS.

When the NWS UA observations resume, the RRS will be gathering meteorological data from Global Positioning System (GPS) radiosondes. The NWS describes the RRS release point location with the National Geodetic Survey (NGS) OPUS solution. This is a datum combination that relies on North American Datum of 1983 (NAD83) for latitude and longitude whereas the release point elevation is based on North American Vertical Datum 1988 (NAVD88) with the GEOID03 model. By contrast the GPS radiosonde flight information of latitude and longitude and altitude will rely on the world geodetic system of 1984 (WGS84) standard. Parts of the UA coded messages will be significantly longer with RRS conversion. NWS has coordinated with its partners on the longer length of these messages. The format of the messages will be the same WMO format for coded UA messages used with the MicroArt legacy system. The number of levels in the coded messages will be two to three times greater for the TTBB and TTDD. As a result two categories of AWIPS text products will increase in size: SGL and ABV. The number of levels in the TTAA, TTCC, PPBB and PPDD parts will be relatively unchanged. These changes reflect updated coding practices and higher resolution level selection criteria. The maximum size limits of the parts of the coded messages are as follows: TTAA: 15 Levels TTCC: 10 Levels TTBB: 135 Levels TTDD: 40 Levels PPBB: 40 Levels PPDD: 40 Levels In addition the 31313 message indicator associated with various parts of the message will be included with each part of the thermodynamic message parts.

This pressure is generated by first relaxing the underground virtual temperature and then integrating the hydrostatic equation downward. The field will be subject to Spectral Gibsing near the coast, but this will be addressed in a future implementation. The three model changes and the 192 hr precipitation change listed above are designed to address shortfalls introduced with the 27 July 2010 GFS resolution increase. The issues being addressed are: --increased low level warm bias over land --negative temperature bias in the stratosphere --negative wind speed bias in the stratosphere --error in the calculation of the 12 hr accumulated precipitation at 192 hrs only.

A determination will be made on Monday May 9. There is a high likelihood that Tuesday, May 10, will be declared a Critical Weather, preventing this GFS implementation from proceeding for indeterminate time. The NCEP Senior Duty Meteorologist will issue a NOUS42 administrative message when the implementation has taken place. Amended to reschedule the implementation from April 26, 2011, to May 10, 2011 to allow for a full evaluation period. Also amended to include details of a new sea level pressure field being added to select products available via the ftp servers. Effective May 10, 2011, beginning with the 1200 Coordinated Universal Time (UTC) run, the National Centers for Environmental Prediction (NCEP) will upgrade the GFS. The upgrade includes: Analysis Changes: --Improve Ozone Monitoring Instrument (OMI) quality control --Remove redundant SBUV/2 total ozone --Retune SBUV/2 ozone observation errors --Relax AMSU-A Channel 5 quality control --Update Community Radiative Transfer Model(CRTM) to version 2.0.2 --Include field of view size/shape/power for radiative transfer --Remove down weighting of collocated radiances --Limit moisture greater than= 1.e-10 in each outer iteration and at end of analysis --Include uniform (higher resolution) thinning for satellite radiances --Improve location of buoys in vertical (move from 20m to 10m) --Improve Gridpoint Statistical Interpolation (GSI) code with optimization and additional options --Recompute background errors --Include SBUV from NOAA-19 --Ambiguous vector quality control for ASCAT (type 290) data Model Changes: --Set new thermal roughness length --Set minimum moisture value in Stratosphere to 1.0x10-7 --Reduce background diffusion in the Stratosphere Product Changes: -Correct error in the 192 hr, 12-hr precipitation bucket -Addition of a new membrane sea level pressure (SLP) field to the 0.5, 1.0 and 2.5 degree pressure grib (pgrb) files only. This pressure is generated by first relaxing the underground virtual temperature and then integrating the hydrostatic equation downward. The field will be subject to Spectral Gibsing near the coast, but this will be addressed in a future implementation. The three model changes and the 192 hr precipitation change listed above are designed to address shortfalls introduced with the 27 July 2010 GFS resolution increase. The issues being addressed are: --increased low level warm bias over land --negative temperature bias in the stratosphere --negative wind speed bias in the stratosphere --error in the calculation of the 12 hr accumulated precipitation at 192 hrs only.

Specific dates are as follows: STATION NAME WMO # STN ID OUTAGE DATES CHUUK 91334 PTKK 25 Apr 2011 POHNPEI 91348 PTPN 05 May 2011 MAJURO 91376 PMKJ 16 May 2011 These UA sites may be out of service for as long as 10 days. When the NWS UA observations resume, the RRS will be gathering meteorological data from Global Positioning System (GPS) radiosondes. The NWS describes the RRS release point location with the National Geodetic Survey (NGS) OPUS solution. This is a datum combination that relies on North American Datum of 1983 (NAD83) for latitude and longitude, whereas the release point elevation is based on North American Vertical Datum 1988 (NAVD88) with the GEOID03 model. By contrast the GPS radiosonde flight information of latitude and longitude and altitude will rely on the world geodetic system of 1984 (WGS84) standard. Parts of the UA coded messages will be significantly longer with RRS conversion. NWS has coordinated with its partners on the longer length of these messages. The format of the messages will be the same WMO format for coded UA messages used with the MicroArt legacy system. The number of levels in the coded messages will be two to three times greater for the TTBB and TTDD. As a result two categories of AWIPS text products will increase in size: SGL and ABV. The number of levels in the TTAA, TTCC, PPBB and PPDD parts will be relatively unchanged. These changes reflect updated coding practices and higher resolution level selection criteria. The maximum size limits of the parts of the coded messages are as follows: TTAA: 15 Levels TTCC: 10 Levels TTBB: 135 Levels TTDD: 40 Levels PPBB: 40 Levels PPDD: 40 Levels In addition the 31313 message indicator associated with various parts of the message will be included with each part of the thermodynamic message parts. For additional information on the message requirements, see WMO 306 Manual on Codes (International Codes): Volume I.1 Part A - Alphanumeric Codes and Volume II Regional Codes and National Coding Practices.

The scientific changes to the model include the following: - Upgrade Simplified Arakawa-Schubert (SAS) deep convection parameterization to new version implemented in the NCEP Global Forecast System (GFS) - Modify the surface enthalpy exchange coefficient and dissipative heating effect - Expand coupled region in the Eastern Atlantic domain to prevent storms from losing coupling effect with the ocean due to insufficient overlap with the Western Atlantic region. The new overlap will be 25 degrees. - Correct several bugs in the model. In testing, these improvements resulted in an average reduction of forecast error of about 20 percent in the Atlantic basin for the 3 to 5 day forecast period for tests of storms from the 2010 Atlantic hurricane season. Product Changes: The following will be added to the GFDL model output GRIB files: Model-predicted 10 meter winds will be outputted in addition to the lowest model level 35 meter winds. The GFDL hurricane model GRIB products are disseminated via the NCEP and NWS FTP servers and are not available on NOAAPORT or AWIPS. These changes will result in no change in product dissemination time. There will be only a minor increase in product size. Once implemented, the GFDL data will be available on the NWS ftp server at: ftp://tgftp.nws.noaa.gov/SL.us008001/ST.opnl/MT.ghm_CY.xx where xx is the model cycle and at the NCEP servers at: www.ftp.ncep.noaa.gov/data/nccf/com/hur/prod/hur.YYYYMMDDHH and ftp.ncep.noaa.gov/pub/data/nccf/com/hur/prod/hur.YYYYMMDDHH where YYYY is year, MM is month, DD is day, and HH is model cycle.

The NAEFS output is derived by combining the NCEP Global Ensemble Forecast System (GEFS) and the Canadian Meteorological Center’s (CMC) GEFS. At this time, NCEP receives raw GEFS output from CMC and bias-corrects the dataset locally before use in NAEFS calculations. With this implementation, NCEP will receive bias-corrected CMC GEFS data directly from CMC, and will no longer compute the bias corrections at NCEP. This will result in a slight difference in the CMC data used in NAEFS. Both modeling centers use the same bias-correction algorithm but minor differences arise due to two factors: First, NCEP and CMC run their bias correction algorithms on slightly different model grids. Second, NCEP computed the CMC bias corrections using data up to the previous day, while CMC calculates the bias correction using data that includes the current day’s values. Tests have shown the differences in the CMC bias-corrected dataset and the NCEP version of CMC bias- corrected data to be minor. There will be no changes in the content of NAEFS products with this implementation. NCEP encourages all users to ensure their decoders are flexible and are able to adequately handle changes in content order, changes in the scaling factor component within the product definition section (PDS) of the GRIB files, and also any volume changes which may be forthcoming.

These changes include: -Introducing a new modeling framework -Installing a major upgrade to the prediction model -Modifying the data analysis and assimilation system -Adding to existing NAM products -Adding new higher-resolution nests within the NAM including a very high-resolution but small domain to support fire weather and Incident Meteorologist (IMET) interests. Details on the various changes are provided below, along with a notice about possible changes to product generation time. Model Upgrades: NCEP will introduce the use of the new NOAA Environmental Modeling System (NEMS), which is based on the tenets put forth by the Earth System Modeling Framework to which NOAA has subscribed. Eventually all of NCEP’s major modeling will be performed within NEMS. This NAM upgrade represents the first implementation of NEMS and a major step in the evolution of NCEP’s modeling suite. The prediction model used in the NAM run will go from being the strictly regional Nonhydrostatic Mesoscale Model (NMM) to a new extended capability version now known as Nonhydrostatic Multiscale Model on B-grid (NMMB), which can be run either regionally or globally, and with or without embedded nests. This NEMS-NMMB will also serve as the prediction model running in the NAM Data Assimilation System (NDAS). Model changes/ enhancements in the NEMS-NMMB will include: a) Native horizontal grid is an Arakawa staggered B-grid (rotated 45 deg from the Arakawa E-grid in the WRF-NMM NAM) b) New more conservative Eulerian advection scheme for passive tracers like water vapor condensate fields c) Generalized vertical coordinate d) Modified vertical level distribution with more layers in the stratosphere (14 layers above 200 mb instead of 7 in the current operational NAM) e) Boundary condition treatment changed to specify 5 boundary rows instead of one. f) Microphysics changes to produce higher peak reflectivities above 45 dBZ with higher peak surface rainfall rates in the high-resolution nests and more realistic grid-scale cloud fractions from cold, high cirrus. g) Change from USGS to MODIS_IGBP land-use definitions h) Enhanced diffusion for specific humidity and cloud water i) Run 5 high-resolution nested domains inside the 12km NAM every cycle. These nests will run with greatly reduced convective triggering, which improved quantitative precipitation forecast (QPF) bias compared to using explicit convection. All model changes will also be applied to the Downscaled GFS by NAM Extension (DGEX) forecast system. NDAS Changes: a) Initial first guess at T-12hr will reflect relocation of tropical cyclones b) Will use 1/12 degree high resolution real-time sea surface temperature (RTG_SST_HR) analysis instead of the 1/2th degree real-time SST analysis. c) Will update 2 m temperature and moisture and 10 m wind with portion of first layer correction Changes to the Gridscale Statistical Interpolation (GSI) analysis: a) New faster version of the GSI code with new observation error estimates, retuned background error covariances for NMMB and upgraded radiative transfer (CRTM v2.0.2) b) Assimilation of new observations: ACARS humidity, Windsat and ASCAT (superob'ed Scatterometer winds over oceans), HIRS radiances from NOAA-19, AMSU-A radiances from NOAA-19 and AQUA, IASI radiances from METOP, GPS radio occultation refractivity (COSMIC), RASS virtual temperatures, MAP (boundary layer profiler) winds and MESONET surface pressure/temperature/ humidity (winds already included) c) Use dynamic reject list for surface mesonet data from the NCEP Real-time Mesoscale Analysis (RTMA) Changes to the NAM post-processing code: a) The height and wind speed at the maximum wind level will be computed by assuming the wind speed varies quadratically in height in the neighborhood of the maximum wind level with the search being capped at 100mb. The previous algorithm defines maximum wind level as the level with the maximum wind speed among all the model levels. b) The static Tropopause level will be obtained by finding the lowest level that has a temperature lapse rate of less than 2 K/km over a 2km depth above it. If no such level is found below 50 mb, the Tropopause is set to 50 mb. The previous algorithm defines the Tropopause by finding the lowest level that has mean temperature lapse rate of 2 K/Km over three model layers. c) All Convective Available Potential Energy (CAPE), Convective Inhibition (CIN), and Lifted Index (LI) variables in the NAM output will be computed using virtual temperature instead of sensible temperature. See the NWS Public Information Statement issued January 12, 2011 for more details on this change. Users should be aware that this NAM upgrade will impact all downstream models and systems that use the NAM or NDAS as input. Output Product Changes: New NAM Nest runs, including placeable Fire Weather Nest: Five new high-resolution nested domains will run inside the 12 km NAM every cycle: a) CONUS (4 km resolution, 0-60 h) b) Alaska (6 km resolution, 0-60 h) c) Hawaii and Puerto Rico (both 3 km resolution, 0-60 h) d) Placeable nest will run to 36-h inside either the CONUS nest (at 1.33 km resolution) or Alaska nest (at 1.5 km resolution). This nest is primarily for Fire Weather/IMET-DHS Support (FWIS). The locations of this domain for each of the 4 NAM cycles will be determined via a daily coordination call conducted by the NCEP Senior Duty Meteorologist. A sample display of the domain coverage of these new nests is available at: www.emc.ncep.noaa.gov/mmb/mmbpll/misc/nmmb_domains.png Output grids from the NAM nest runs will be available on the NCEP ftp server immediately and on the NCEP NOMADS server in the future. The fields contained in the NAM nest output grids are listed at: www.emc.ncep.noaa.gov/mmb/mmbpll/misc/sampleinv_namnests.html Changes to parent NAM gridded output on the NCEP ftp server and the NWS ftp server: a) In all NAM grids that contain roughness length, the precision was changed to provide better decimal scaling because many land- use types have roughness length much less than 1. b) Surface slope type was dropped from all NAM output grids as it is no longer used in the model land-surface physics c) Time-averaged surface momentum flux record is being removed from all NAM GRIB files as it is not defined and thus had been set to zero in the current operational NAM d) New output fields: - Clear Air Turbulence (Ellrod Index), every 25 mb from 150-525 mb, and Inflight Icing every 25 mb from 300-600 mb, every 50 mb from 650-950 mb, and 725 mb; added to grid #221 (32 km grid over North America) - 80 km above ground level pressure, temperature, wind, and specific humidity; added to grid #221 (32 km grid over North America), grid #218 (12 km grid over CONUS, pressure file only) and grid #242 (11.25 km grid over Alaska, pressure file only). - Hourly max and min surface fields (10-meter wind, 2-meter temperature, 2-meter relative humidity); added to grid #221 (32 km grid over North America), grid #218 (12 km grid over CONUS, both versions) and grid #242 (11.25 km grid over Alaska). - Haines Index: Added to grid #218 (12 km grid over CONUS, both versions) and grid #242 (11.25 km grid over Alaska, both versions) - Ventilation Rate: Added to grid #218 (12 km grid over CONUS) and grid #242 (11.25 km grid over Alaska). - Rain and snow on lowest model level: added to grid #218 surface file "awip12" - Thunder parameter (called lightning in GRIB): added to both grid #218 files e) All NAM output files on the native horizontal staggered E-grid of the current operational WRF-NMM will be on the staggered B-grid of the NEMS-NMMB. The current native grid files with names "egrd3d," "edgawp," and "egrdsf" will be removed from the NCEP FTP server and replaced with files with names "bgrd3d", "bgdawp," and "bgrdsf," respectively. Users who process current NAM native GRIB files with e-grid staggering will need to modify their software to process b-grid staggering. f) To provide the critical variables used at Weather Forecast Offices to generate their National Digital Forecast Database (NDFD) forecast grids, NCEP will begin to populate the current NAM Downscaled Numerical Guidance (DNG – a small set of 2- dimensional fields) in the 0–60 hr range from the new high- resolution NAM nested fields instead of the parent NAM 12 km fields. The NAM DNG grids are currently distributed to CONUS, Alaska, Hawaii and Puerto Rico over the AWIPS SBN/NOAAPORT. In response to requests from the NWS Regions, NCEP also plans on producing a CONUS 2.5km NAM-DNG for the 0-60 hr in addition to the current CONUS 5 km version. A separate TIN will announce the addition of those 2.5 km grids to NOAAPORT. Product Delivery Time Change: NCEP anticipates that output delivery times after the NAM upgrade will differ slightly throughout the run compared to the current operational NAM products. The precise amounts still need to come out of the final pre-implementation testing by NCEP Central Operations, but the following is the worst case scenario. When the CONUS Fire Weather nest is run during the first 36 hours of the forecast, product delivery will lag the current delivery by ~13 seconds each forecast hour such that 36 hour guidance will be 468 seconds or 7.8 minutes later than at present. Following the 36 hour point of the forecast, NWS will recover delivery time at roughly 10 seconds each forecast hour such that delivery of the 84 hr guidance will be at the same time as it is delivered today, which is 10 minutes earlier than its target. As an example, for 0000UTC run, the following delivery time differences would be expected, with current time in parentheses: 12hr PRODUCTS at 01:52:52 (01:50:16) 24hr PRODUCTS at 02:05:26 (02:00:14) 36hr PRODUCTS at 02:17:49 (02:10:01) 48hr PRODUCTS at 02:25:47 (02:19:59) 60hr PRODUCTS at 02:34:04 (02:30:16) 72hr PRODUCTS at 02:40:23 (02:38:35) 84hr PRODUCTS at 02:50:23 (02:50:35) The target delivery for 84 hr guidance is 3:00:00. When the fire weather nest is over Alaska, product delivery will lag the current delivery by ~5 seconds each forecast hour such that 36 hour guidance will be 180 seconds or 3 minutes later than at present.

NCEP urges all users to ensure their decoders can handle changes in content order, changes in the scaling factor component within the product definition section (PDS) of the GRIB files, and volume changes. These elements may change with future NCEP model implementations. NCEP will make every attempt to alert users to these changes before implementation.

Details on the various changes are provided below, along with a notice about possible changes to product generation time. Model Upgrades: NCEP will introduce the use of the new NOAA Environmental Modeling System (NEMS), which is based on the tenets put forth by the Earth System Modeling Framework to which NOAA has subscribed. Eventually all of NCEP’s major modeling will be performed within NEMS. This NAM upgrade represents the first implementation of NEMS and a major step in the evolution of NCEP’s modeling suite. The prediction model used in the NAM run will go from being the strictly regional Nonhydrostatic Mesoscale Model (NMM) to a new extended capability version now known as Nonhydrostatic Multiscale Model on B-grid (NMMB), which can be run either regionally or globally, and with or without embedded nests. This NEMS-NMMB will also serve as the prediction model running in the NAM Data Assimilation System (NDAS). Model changes/ enhancements in the NEMS-NMMB will include: a) Native horizontal grid is an Arakawa staggered B-grid (rotated 45 deg from the Arakawa E-grid in the WRF-NMM NAM) b) New more conservative Eulerian advection scheme for passive tracers like water vapor condensate fields c) Generalized vertical coordinate d) Modified vertical level distribution with more layers in the stratosphere (14 layers above 200 mb instead of 7 in the current operational NAM) e) Boundary condition treatment changed to specify 5 boundary rows instead of one f) Microphysics changes to produce higher peak reflectivities above 45 dBZ with higher peak surface rainfall rates in the high-resolution nests and more realistic grid-scale cloud fractions from cold, high cirru. g) Change from USGS to MODIS_IGBP land-use definitions h) Enhanced diffusion for specific humidity and cloud water i) Run 5 high-resolution nested domains inside the 12km NAM every cycle. These nests will run with greatly reduced convective triggering, which improved quantitative precipitation forecast (QPF) bias compared to using explicit convection. All model changes will also be applied to the Downscaled GFS by NAM Extension (DGEX) forecast system. NDAS Changes: a) Initial first guess at T-12hr will reflect relocation of tropical cyclones b) Will use 1/12 degree high resolution real-time sea surface temperature (RTG_SST_HR) analysis instead of the 1/2th degree real-time SST analysis. c) Will update 2 m temperature and moisture and 10 m wind with portion of first layer correction Changes to the Gridscale Statistical Interpolation (GSI) analysis: a) New faster version of the GSI code with new observation error estimates, retuned background error covariances for NMMB and upgraded radiative transfer (CRTM v2.0.2) b) Assimilation of new observations: ACARS humidity, Windsat and ASCAT (superob'ed Scatterometer winds over oceans), HIRS radiances from NOAA-19, AMSU-A radiances from NOAA-19 and AQUA, IASI radiances from METOP, GPS radio occultation refractivity (COSMIC), RASS virtual temperatures, MAP (boundary layer profiler) winds and MESONET surface pressure/temperature/ humidity (winds already included) c) Use dynamic reject list for surface mesonet data from the NCEP Real-time Mesoscale Analysis (RTMA) Changes to the NAM post-processing code: a) The height and wind speed at the maximum wind level will be computed by assuming the wind speed varies quadratically in height in the neighborhood of the maximum wind level with the search being capped at 100mb. The previous algorithm defines maximum wind level as the level with the maximum wind speed among all the model levels. b) The static Tropopause level will be obtained by finding the lowest level that has a temperature lapse rate of less than 2 K/km over a 2km depth above it. If no such level is found below 50 mb, the Tropopause is set to 50 mb. The previous algorithm defines the Tropopause by finding the lowest level that has mean temperature lapse rate of 2 K/Km over three model layers. c) All Convective Available Potential Energy (CAPE), Convective Inhibition (CIN), and Lifted Index (LI) variables in the NAM output will be computed using virtual temperature instead of sensible temperature. See the NWS Public Information Statement issued January 12, 2011 for more details on this change. Users should be aware that this NAM upgrade will impact all downstream models and systems that use the NAM or NDAS as input. Output Product Changes: New NAM Nest runs, including placeable Fire Weather Nest: Five new high-resolution nested domains will run inside the 12 km NAM every cycle: a) CONUS (4 km resolution, 0-60 h) b) Alaska (6 km resolution, 0-60 h) c) Hawaii and Puerto Rico (both 3 km resolution, 0-60 h) d) Placeable nest will run to 36-h inside either the CONUS nest (at 1.33 km resolution) or Alaska nest (at 1.5 km resolution). This nest is primarily for Fire Weather/IMET-DHS Support (FWIS). The locations of this domain for each of the 4 NAM cycles will be determined via a daily coordination call conducted by the NCEP Senior Duty Meteorologist. A sample display of the domain coverage of these new nests is available at: www.emc.ncep.noaa.gov/mmb/mmbpll/misc/nmmb_domains.png Output grids from the NAM nest runs will be available on the NCEP ftp server immediately and on the NCEP NOMADS server in the future. The fields contained in the NAM nest output grids are listed at: www.emc.ncep.noaa.gov/mmb/mmbpll/misc/sampleinv_namnests.html Changes to parent NAM gridded output on the NCEP ftp server and the NWS ftp server: a) In all NAM grids that contain roughness length, the precision was changed to provide better decimal scaling because many land-use types have roughness length much less than 1. b) Surface slope type was dropped from all NAM output grids as it is no longer used in the model land-surface physics c) Time-averaged surface momentum flux record is being removed from all NAM GRIB files as it is not defined and thus had been set to zero in the current operational NAM d) New output fields: - Clear Air Turbulence (Ellrod Index), every 25 mb from 150-525 mb, and Inflight Icing every 25 mb from 300-600 mb, every 50 mb from 650-950 mb, and 725 mb; added to grid #221 (32 km grid over North America) - 80 km above ground level pressure, temperature, wind, and specific humidity; added to grid #221 (32 km grid over North America), grid #218 (12 km grid over CONUS, pressure file only) and grid #242 (11.25 km grid over Alaska, pressure file only). - Hourly max and min surface fields (10-meter wind, 2-meter temperature, 2-meter relative humidity); added to grid #221 (32 km grid over North America), grid #218 (12 km grid over CONUS, both versions) and grid #242 (11.25 km grid over Alaska). - Haines Index: Added to grid #218 (12 km grid over CONUS, both versions) and grid #242 (11.25 km grid over Alaska, both versions) - Ventilation Rate: Added to grid #218 (12 km grid over CONUS) and grid #242 (11.25 km grid over Alaska). - Rain and snow on lowest model level: added to grid #218 surface file "awip12" - Thunder parameter (called lightning in GRIB): added to both grid #218 files e) All NAM output files on the native horizontal staggered E-grid of the current operational WRF-NMM will be on the staggered B-grid of the NEMS-NMMB. The current native grid files with names "egrd3d," "edgawp," and "egrdsf" will be removed from the NCEP FTP server and replaced with files with names "bgrd3d", "bgdawp," and "bgrdsf," respectively. Users who process current NAM native GRIB files with e-grid staggering will need to modify their software to process b-grid staggering. f) To provide the critical variables used at Weather Forecast Offices to generate their National Digital Forecast Database (NDFD) forecast grids, NCEP will begin to populate the current NAM Downscaled Numerical Guidance (DNG - a small set of 2-dimensional fields) in the 0-60 hr range from the new high-resolution NAM nested fields instead of the parent NAM 12 km fields. The NAM DNG grids are currently distributed to CONUS, Alaska, Hawaii and Puerto Rico over the AWIPS SBN/NOAAPORT. In response to requests from the NWS Regions, NCEP also plans on producing a CONUS 2.5km NAM-DNG for the 0-60 hr in addition to the current CONUS 5 km version. A separate TIN will announce the addition of those 2.5 km grids to NOAAPORT. g) Several users have noted differences in the precision of the accumulated precipitation at different forecast projections. With this upgrade, the precision for all forecast hours will be standardized. Product Delivery Time Change: NCEP anticipates that output delivery times after the NAM upgrade will differ slightly throughout the run compared to the current operational NAM products. The precise amounts still need to come out of the final pre-implementation testing by NCEP Central Operations, but the following is the worst case scenario. When the CONUS Fire Weather nest is run during the first 36 hours of the forecast, product delivery will lag the current delivery by ~13 seconds each forecast hour such that 36 hour guidance will be 468 seconds or 7.8 minutes later than at present. Following the 36 hour point of the forecast, NWS will recover delivery time at roughly 10 seconds each forecast hour such that delivery of the 84 hr guidance will be at the same time as it is delivered today, which is 10 minutes earlier than its target. As an example, for 0000UTC run, the following delivery time differences would be expected, with current time in parentheses: 12hr PRODUCTS at 01:52:52 (01:50:16) 24hr PRODUCTS at 02:05:26 (02:00:14) 36hr PRODUCTS at 02:17:49 (02:10:01) 48hr PRODUCTS at 02:25:47 (02:19:59) 60hr PRODUCTS at 02:34:04 (02:30:16) 72hr PRODUCTS at 02:40:23 (02:38:35) 84hr PRODUCTS at 02:50:23 (02:50:35) The target delivery for 84 hr guidance is 3:00:00. When the fire weather nest is over Alaska, product delivery will lag the current delivery by ~5 seconds each forecast hour such that 36 hour guidance will be 180 seconds or 3 minutes later than at present.

The parallel data will be available via the following URLs: http://www.ftp.ncep.noaa.gov/data/nccf/com/nam/para ftp://ftp.ncep.noaa.gov/pub/data/nccf/com/nam/para NCEP has tried to anticipate all filename and product content changes associated with this implementation, but if we discover additional changes during the course of the testing, we will send an amended version of this TIN with that information as soon as possible. NCEP urges all users to ensure their decoders can handle changes in content order, changes in the scaling factor component within the product definition section (PDS) of the GRIB files, and volume changes. These elements may change with future NCEP model implementations. NCEP will make every attempt to alert users to these changes before implementation.

When the fire weather nest is over Alaska, product delivery will lag the current delivery by ~5 seconds each forecast hour such that 36 hour guidance will be 180 seconds or 3 minutes later than at present.

The fields contained in the NAM nest output grids are listed at: www.emc.ncep.noaa.gov/mmb/mmbpll/misc/sampleinv_namnests.html Changes to parent NAM gridded output on the NCEP ftp server and the NWS ftp server: a) In all NAM grids that contain roughness length, the precision was changed to provide better decimal scaling because many land-use types have roughness length much less than 1. b) Surface slope type was dropped from all NAM output grids as it is no longer used in the model land-surface physics c) Time-averaged surface momentum flux record is being removed from all NAM GRIB files as it is not defined and thus had been set to zero in the current operational NAM d) New output fields: - Clear Air Turbulence (Ellrod Index), every 25 mb from 150-525 mb, and Inflight Icing every 25 mb from 300-600 mb, every 50 mb from 650-950 mb, and 725 mb; added to grid #221 (32 km grid over North America) - 80 km above ground level pressure, temperature, wind, and specific humidity; added to grid #221 (32 km grid over North America), grid #218 (12 km grid over CONUS, pressure file only) and grid #242 (11.25 km grid over Alaska, pressure file only). - Hourly max and min surface fields (10-meter wind, 2-meter temperature, 2-meter relative humidity); added to grid #221 (32 km grid over North America), grid #218 (12 km grid over CONUS, both versions) and grid #242 (11.25 km grid over Alaska). - Haines Index: Added to grid #218 (12 km grid over CONUS, both versions) and grid #242 (11.25 km grid over Alaska, both versions) - Ventilation Rate: Added to grid #218 (12 km grid over CONUS) and grid #242 (11.25 km grid over Alaska). - Rain and snow on lowest model level: added to grid #218 surface file "awip12" - Thunder parameter (called lightning in GRIB): added to both grid #218 files e) All NAM output files on the native horizontal staggered E-grid of the current operational WRF-NMM will be on the staggered B-grid of the NEMS-NMMB. The current native grid files with names "egrd3d," "edgawp," and "egrdsf" will be removed from the NCEP FTP server and replaced with files with names "bgrd3d", "bgdawp," and "bgrdsf," respectively. Users who process current NAM native GRIB files with e-grid staggering will need to modify their software to process b-grid staggering. f) To provide the critical variables used at Weather Forecast Offices to generate their National Digital Forecast Database (NDFD) forecast grids, NCEP will begin to populate the current NAM Downscaled Numerical Guidance (DNG - a small set of 2-dimensional fields) in the 0-60 hr range from the new high-resolution NAM nested fields instead of the parent NAM 12 km fields. The NAM DNG grids are currently distributed to CONUS, Alaska, Hawaii and Puerto Rico over the AWIPS SBN/NOAAPORT. In response to requests from the NWS Regions, NCEP also plans on producing a CONUS 2.5km NAM-DNG for the 0-60 hr in addition to the current CONUS 5 km version. A separate TIN will announce the addition of those 2.5 km grids to NOAAPORT. g) Several users have noted differences in the precision of the accumulated precipitation at different forecast projections. With this upgrade, the precision for all forecast hours will be standardized. Product Delivery Time Change: NCEP anticipates that output delivery times after the NAM upgrade will differ slightly throughout the run compared to the current operational NAM products. The precise amounts still need to come out of the final pre-implementation testing by NCEP Central Operations, but the following is the worst case scenario. When the CONUS Fire Weather nest is run during the first 36 hours of the forecast, product delivery will lag the current delivery by ~13 seconds each forecast hour such that 36 hour guidance will be 468 seconds or 7.8 minutes later than at present. Following the 36 hour point of the forecast, NWS will recover delivery time at roughly 10 seconds each forecast hour such that delivery of the 84 hr guidance will be at the same time as it is delivered today, which is 10 minutes earlier than its target. As an example, for 0000UTC run, the following delivery time differences would be expected, with current time in parentheses: 12hr PRODUCTS at 01:52:52 (01:50:16) 24hr PRODUCTS at 02:05:26 (02:00:14) 36hr PRODUCTS at 02:17:49 (02:10:01) 48hr PRODUCTS at 02:25:47 (02:19:59) 60hr PRODUCTS at 02:34:04 (02:30:16) 72hr PRODUCTS at 02:40:23 (02:38:35) 84hr PRODUCTS at 02:50:23 (02:50:35) The target delivery for 84 hr guidance is 3:00:00. When the fire weather nest is over Alaska, product delivery will lag the current delivery by ~5 seconds each forecast hour such that 36 hour guidance will be 180 seconds or 3 minutes later than at present.

NCEP urges all users to ensure their decoders can handle changes in content order, changes in the scaling factor component within the product definition section (PDS) of the GRIB files, changes to the GRIB Bit Map Section (BMS), and volume changes. These elements may change with future NCEP model implementations. NCEP will make every attempt to alert users to these changes before implementation.

Users are reminded that declaration of a Critical Weather Day (CWD) may result in the NAM being implemented on or around the October 18. Effective on Tuesday, October 18, 2011, with the 1200 UTC cycle, the National Centers for Environmental Prediction (NCEP) will modify the NAM Analysis and Forecast System. These changes include: -Introducing a new modeling framework -Installing a major upgrade to the prediction model -Modifying the data analysis and assimilation system -Adding to existing NAM products -Adding new higher-resolution nests within the NAM including a very high-resolution but small domain to support fire weather and Incident Meteorologist (IMET) interests Details on the various changes are provided below, along with a notice about possible changes to product generation time. Model Upgrades NCEP will introduce the use of the new NOAA Environmental Modeling System (NEMS), which is based on the tenets put forth by the Earth System Modeling Framework to which NOAA has subscribed. Eventually all of NCEP’s major modeling will be performed within NEMS. This NAM upgrade represents the first implementation of NEMS and a major step in the evolution of NCEP’s modeling suite. The prediction model used in the NAM run will go from being the strictly regional Nonhydrostatic Mesoscale Model (NMM) to a new extended capability version now known as Nonhydrostatic Multiscale Model on B-grid (NMMB), which can be run either regionally or globally with or without embedded nests. This NEMS-NMMB also will serve as the prediction model running in the NAM Data Assimilation System (NDAS). Model changes/enhancements in the NEMS-NMMB will include the following: a) Native horizontal grid is an Arakawa staggered B-grid (rotated 45 deg. from the Arakawa E-grid in the WRF-NMM NAM) b) New more conservative Eulerian advection scheme for passive tracers like water vapor condensate fields c) Generalized vertical coordinate d) Modified vertical level distribution with more layers in the stratosphere (14 layers above 200 mb instead of 7 in the current operational NAM) e) Boundary condition treatment changed to specify 5 boundary rows instead of 1 f) Microphysics changes to produce higher peak reflectivities above 45 dBZ, with higher peak surface rainfall rates in the high-resolution nests and more realistic grid-scale cloud fractions from cold, high cirru g) Change from USGS to MODIS_IGBP land-use definitions h) Enhanced diffusion for specific humidity and cloud water i) Run 5 high-resolution nested domains inside the 12km NAM every cycle. These nests will run with greatly reduced convective triggering, which improved quantitative precipitation forecast (QPF) bias compared to using explicit convection All model changes will also be applied to the Downscaled GFS by NAM Extension (DGEX) forecast system. NDAS Changes: a) Initial first guess at T-12hr will reflect relocation of tropical cyclones b) Will use 1/12 degree high resolution real-time sea surface temperature (RTG_SST_HR) analysis instead of the 1/2 degree real-time SST analysis. c) Will update 2 m temperature and moisture and 10 m wind with portion of first layer correction Changes to the Gridscale Statistical Interpolation (GSI) analysis: a) New faster version of the GSI code with new observation error estimates, retuned background error covariances for NMMB and upgraded radiative transfer (CRTM v2.0.2) b) Assimilation of new observations: ACARS humidity, Windsat and ASCAT (superob'ed Scatterometer winds over oceans), HIRS radiances from NOAA-19, AMSU-A radiances from NOAA-19 and AQUA, IASI radiances from METOP, GPS radio occultation refractivity (COSMIC), RASS virtual temperatures, MAP (boundary layer profiler) winds and MESONET surface pressure/temperature/ humidity (winds already included) c) Use dynamic reject list for surface mesonet data from the NCEP Real-time Mesoscale Analysis (RTMA) Changes to the NAM post-processing code: a) The height and wind speed at the maximum wind level will be computed by assuming the wind speed varies quadratically in height in the neighborhood of the maximum wind level with the search being capped at 100mb. The previous algorithm defines maximum wind level as the level with the maximum wind speed among all the model levels. b) The static Tropopause level will be obtained by finding the lowest level that has a temperature lapse rate of less than 2K/km over a 2km depth above it. If no such level is found below 50 mb, the Tropopause is set to 50 mb. The previous algorithm defines the Tropopause by finding the lowest level with a mean temperature lapse rate of 2K/Km over three model layers. c) All Convective Available Potential Energy (CAPE), Convective Inhibition (CIN), and Lifted Index (LI) variables in the NAM output will be computed using virtual temperature instead of sensible temperature. See the NWS Public Information Statement issued January 12, 2011, for more details on this change. Users should be aware that this NAM upgrade will impact all downstream models and systems using the NAM or NDAS as input. Output Product Changes: New NAM Nest runs, including placeable Fire Weather Nest. Five new high-resolution nested domains will run inside the 12 km NAM every cycle: a) CONUS (4 km resolution, 0-60 h) b) Alaska (6 km resolution, 0-60 h) c) Hawaii and Puerto Rico (both 3 km resolution, 0-60 h) d) Placeable nest will run to 36-h inside either the CONUS nest (at 1.33 km resolution) or Alaska nest (at 1.5 km resolution). This nest is primarily for Fire Weather/IMET-DHS Support (FWIS). The locations of this domain for each of the 4 NAM cycles will be determined via a daily coordination call conducted by the NCEP Senior Duty Meteorologist. A sample display of the domain coverage of these new nests is available at: www.emc.ncep.noaa.gov/mmb/mmbpll/misc/nmmb_domains.png Output grids from the NAM nest runs will be available on the NCEP ftp server immediately and on the NCEP NOMADS server in the future.

More information regarding the HIRESW and associated products can be found at: http://www.emc.ncep.noaa.gov/mmb/mmbpll/nestpage_4km The WMO headers for these HIRESW GRIB2 products are L*x*** KWBS or M*x*** KWBS where x = A for Eastern US B for Western US C for Alaska D for Hawaii E for Puerto Rico F for Guam. A complete explanation of the WMO headers for all of the products is available at: www.nco.ncep.noaa.gov/pmb/changes/hiresw_wmo_headers.shtml The HIRESW output is currently available on the NCEP server at: www.ftp.ncep.noaa.gov/data/nccf/com/hiresw/prod/ and ftp://ftp.ncep.noaa.gov/pub/data/nccf/com/hiresw/prod/ in directories hiresw.YYYYMMDD, where YYYYMMDD is the current year, month and day. The model data for the Guam and Puerto Rico domains will be added to NOAAPORT on August 16; however, the data will not be displayable in the Advanced Weather Interactive Processing System (AWIPS) until future modifications are made.

CCPA 3-hourly accumulated precipitation analyses are generated by splitting each 6-hourly accumulated precipitation analysis based on a ratio calculated from hourly Stage II (over the Northwest River Forecast Center) or Stage IV (over other continental U.S. River Forecast Centers) values at each HRAP grid cell. The analysis is then interpolated from the HRAP grid to other grids. The 3-hourly CCPA covers the same domain as the 6-hourly analysis and is available on the same 5 output grids: 1. HRAP Grid (same as the Stage IV grid) 2. National Digital Forecast Database (NDFD) CONUS grid 3. 0.125 degree CONUS latitude/longitude grid (Grid ID 110) 4. 0.5 degree latitude/longitude grid with data coverage over CONUS only 5. 1.0 degree latitude/longitude grid with data coverage over CONUS only (Grid ID 3) For specifications of Grid IDs 3 and 110, see http://www.nco.ncep.noaa.gov/pmb/docs/on388/tableb.html The 6-hourly CCPA data is currently disseminated via the NCEP server and is available at: http://www.ftp.ncep.noaa.gov/data/nccf/com/gens/prod/gefs.YYYYMM DD/XX/ccpa/ or ftp://ftp.ncep.noaa.gov/pub/data/nccf/com/gens/prod/gefs.YYYYMMD D/XX/ccpa/ where YYYYMMDD is the date and XX is the model cycle. In addition to the currently existing 6-hourly files, on August 23rd there will be 2 new files for each grid, corresponding to the two 3-hourly sub-periods. Data delivery timing will be slightly impacted by this implementation as additional time will be needed to compute the 3-hourly analyses.

The current NAM-DNG products are distributed to the Continental U.S. (CONUS), Alaska, Hawaii and Puerto Rico out to 84 hours over the AWIPS SBN/NOAAPORT and are available on the NCEP server. The new NAM nests are run only to 60 hours but are run at resolutions much closer to the National Digital Forecast Database (NDFD) forecast grids used in the DNG than the 12km NAM, now called the parent grid. After the modification of existing NAM-DNG is, as stated in TIN11-16, the first 60 hours (54 hours) of the current 0000 and 1200 UTC (0600 and 1800 UTC), NAM-DNG will come from the NAM nests instead of from the 12km NAM parent. --CONUS: the 4km NAM nest will feed 5km NAM-DNG. --Alaska: the 6km NAM nest will feed 5.9km NAM-DNG. --Hawaii, Puerto Rico: 3km NAM nests will feed 2.5km NAM-DNG. In this way, only slight downscaling (or upscaling in the case of CONUS) is required. Currently, all systems downscale from 12km. After the change, there may be some unavoidable amount of discontinuity between the NAM-nest-based 60 hr (54 hr for 0600 and 1800 UTC) and the NAM-parent-based 63 hr (57 hr for 0600 and 1800 UTC) guidance. These modifications will occur when the NAM upgrade, detailed in TIN 11-16 linked below, is implemented later this summer. www.weather.gov/os/notification/tin11-16nam_changes_aaa.htm The enhancement of NAM-DNG will come from the addition of NAM-DNG for CONUS and Alaska at double the present NDFD resolution through the 60 hours covered by the NAM nests.

The modifications to the current NAM DNG, as part of the upgrade of the NAM prediction system, will proceed when the NAM upgrade is implemented in mid-October. Effective with the upgrade of the North American Mesoscale (NAM) prediction system, and inclusion of high resolution nests (see TIN 11-16), the National Centers for Environmental Prediction (NCEP) will modify and enhance the suite of NAM Downscaled Numerical Guidance (NAM-DNG). The current NAM-DNG products are distributed to the Continental U.S. (CONUS), Alaska, Hawaii and Puerto Rico out to 84 hours over the AWIPS SBN/NOAAPORT and are available on the NCEP server. The new NAM nests are run only to 60 hours but are run at resolutions much closer to the National Digital Forecast Database (NDFD) forecast grids used in the DNG than the 12km NAM, now called the parent grid. After the modification of existing NAM-DNG is, as stated in TIN11-16, the first 60 hours (54 hours) of the current 0000 and 1200 UTC (0600 and 1800 UTC), NAM-DNG will come from the NAM nests instead of from the 12km NAM parent. --CONUS: 4km NAM nest will feed 5km NAM-DNG --Alaska: 6km NAM nest will feed 5.9km NAM-DNG --Hawaii, Puerto Rico: 3km NAM nests will feed 2.5km NAM-DNG In this way, only slight downscaling (or upscaling in the case of CONUS) is required. Currently, all systems downscale from 12km. After the change, there may be some unavoidable amount of discontinuity between the NAM-nest-based 60-hr (54 hr for 0600 and 1800 UTC) and the NAM-parent-based 63-hr (57 hr for 0600 and 1800 UTC) guidance. These modifications will occur when the NAM upgrade, detailed in TIN11-16 linked below, is implemented later this summer. www.weather.gov/os/notification/tin11-16nam_changes_aaa.htm The enhancement of NAM-DNG will come from the addition of NAM-DNG for CONUS and Alaska at double the present NDFD resolution through the 60 hours covered by the NAM nests. For CONUS, the 4km NAM nest will feed a 2.5km NAM-DNG. For Alaska, the 6km NAM nest will feed a 3km NAM-DNG. Output will be made available every 3 hours from 0-60 hours for all 4 NAM cycles. These new high-resolution NAM-DNG products will be available on the NCEP server when the NAM upgrade is implemented. In addition, simulated composite reflectivity will be added to output for both the modified and enhanced NAM-DNG. The new high- resolution NAM-DNG products will be made available on NOAAPORT once issues with the SBN expansion and at the TOC have been resolved. This TIN will be amended to reflect that activation date once it has been set. The grids listed below in Table 1 for CONUS and Table 2 for Alaska will be available at double NDFD resolutions. NCEP will remove the coarser 5km CONUS and 5.9km Alaska NAM-DNG products from NOAAPORT and all other distribution methods once sufficient time has passed to allow software upgrades.

More specifics, including an implementation date, will be sent in the next two months. Brief Description of Changes: -Change of name of system from Rapid Update Cycle (RUC) to Rapid Refresh (RR) -Replace RUC prediction model with WRF using ARW dynamic core -Replace RUC 3-D variational analysis (3DVAR) with the Gridpoint Statistical Interpolation (GSI) -Expand domain to cover Alaska and Caribbean basin The transition of the Rapid Update Cycle into use of the WRF model has been planned for more than 6 years. The Rapid Refresh configuration allows the system to take advantage of the community development of the WRF model and GSI data assimilation, used in other NCEP systems including NAM and GFS, while maintaining many of the elements of the RUC crucial to aviation and severe weather forecasting, such as the diabatic digital filter initialization, the assimilation of radar reflectivity data, and the analysis of cloud hydrometeors using METAR and satellite data. The Rapid Refresh domain extends hourly "rapid updating" to all of North America, including Alaska and the Caribbean. A full description of the changes can be found on the Earth Sciences Research Laboratory’s web page for the Rapid Refresh: http://rapidrefresh.noaa.gov Please note that the experimental 3-km High-Resolution Rapid Refresh (HRRR) is not part of this implementation. Model products: Most of the output currently available from the RUC will be available for the Rapid Refresh to ensure a smooth transition to the new system. This output includes: - 13, 20, and 40-km Lambert Conformal grid data covering the CONUS region with output on pressure levels - 13, 20, and 40-km Lambert Conformal grid data covering the CONUS region with output on native levels - BUFR model station time series output (with an expanded list of stations to accompany the larger domain) New data will include: - Full-domain output on a 32-km Lambert Conformal grid, the only grid on which data covering the entire domain will be generated) - Alaska data on an 11-km polar-stereographic grid Data that will no longer be available are 80-km Lambert Conformal grid data covering the CONUS region A parallel version of the RR is being run at the Environmental Modeling Center each hour with statistics being computed daily. Forecast graphics are available at http://www.emc.ncep.noaa.gov/mmb/gmanikin/rap/para Formal evaluation will begin in the fall of 2011, with data files available from NCEP Central Operations, which will be running the system in a real-time dedicated parallel. The location of this parallel test data will be sent in a follow-on notification. Users who wish to get a head start on their evaluation of test files to prepare for the transition can obtain them from the EMC parallel at: ftp://ftp.emc.ncep.noaa.gov/mmb/mmbpll/rap NCEP would encourage users to ensure their decoders are flexible and are able to adequately handle changes in content order, parameter fields changing order, changes in the scaling factor component within the Product Definition Section (PDS) of the GRIB files and also any volume changes which may be forthcoming. These elements may change with future NCEP model implementations. NCEP will make every attempt to alert users to these changes prior to any implementation.

The NWS is planning a 1-year field test of an additional scanning angle less than 0.5 degree elevation (initially 0.176 degree) on the new radar to determine the operational benefit(s) of having a lower scan angle. The test is scheduled to begin November 1, 2011. To reduce impacts on users, Level III products will not include data from the lower scanning angle. Thus, the product formats and contents will not change during the field test. Users will notice volume coverage pattern (VCP) durations increase by 30 to 150 seconds when the experimental lower scanning angle is in use. To support the real-time and post-analysis of the impacts of the lower scan angle data, the Level II data stream will include the data from the experimental lower scan angle when in use. The Seattle Weather Forecast Office will be able to turn the lower elevation scan on and off. Details of Level II data changes when the additional test scan angle is being used are as follows: 1. Experimental VCP numbers will increase by two, i.e., VCP11 will be VCP13 2. Lower scan data will be the first radial data in a Level II file 3. The lower scan will be a "Split Cut" Additional information is available at: http://www.wrh.noaa.gov/wrh/washington_coast_doppler_radar/ If you have questions or comments, please contact: Tim Crum WSR-88D Radar Operations Center Tim.D.Crum@noaa.gov National Technical Implementation Notices are online at: http://www.weather.gov/os/notif.htm $$ NNNN Thu, 22 Dec 2011 19:23:05 UTC Donna.Ayers@noaa.gov tin11-39wafs.txt http://www.weather.gov/os/notification/tin11-39wafs.txt World Area Forecast Center (WAFC) Internet File System Operational Effective Thursday, September 8, 2011, at 1400 Coordinated Universal Time (UTC), the NWS Aviation Weather Center in Kansas City, MO, will implement the WAFC Internet File System (WIFS) as an operational system.

Routine and updated TAFS will no longer be issued for this airport. TAF service was initiated for KDRA in the 1970s when nuclear testing personnel were routinely flying into the KDRA airport. At that time, there was significant air traffic into that field. In 1992, flights into KDRA were reduced dramatically when nuclear testing was banned. In 2009, the FAA changed the airport use to private use, with permission required from the Department of Energy (DOE) before landing. The airport has no control tower and is unattended.

Replacing the current LAMP total sky cover guidance with new opaque sky cover guidance which is dependent on cloud opacity. The LAMP sky cover guidance predicts an estimate of the total percentage of the sky covered by clouds in terms of the five categories reported in the METAR observations: clear, few, scattered, broken, or overcast. The current LAMP total sky cover guidance does not distinguish between opaque and translucent cloud cover. The new LAMP sky cover will produce an estimate of opaque clouds. The anticipated effect of this change will be to decrease the number of broken or overcast forecasts and to increase the number of clear or few forecasts when only cirrus clouds are expected. This change will make the LAMP guidance consistent with both the NWS definition of sky cover, as well as the Global Forecast System (GFS)-based MOS definition of sky cover. See TIN 07-34 for details on GFS-based MOS opaque sky cover change. http://www.nws.noaa.gov/os/notification/tin07-34juncloud.txt The LAMP total sky cover currently available in the LAMP public text bulletins (known by their AWIPS ids LAV) and labeled as CLD will be replaced with the LAMP opaque sky cover. The CLD label will not change. Likewise, the LAMP total sky cover currently available in the BUFR message will be replaced with the LAMP opaque sky cover. This change to the LAMP BUFR message will be transparent to users with no changes to the descriptors in the BUFR file. 2. Redeveloped ceiling height and conditional ceiling height equations to produce improved forecast guidance. 3. NWS will add 119 stations to the LAMP text bulletins and BUFR products. These changes will be reflected in the new equations for opaque sky cover, and the redeveloped ceiling height and conditional ceiling height equations. These changes will also be reflected in the guidance for the following elements: Precipitation occurring on the hour Precipitation in a 6-hour period Precipitation in a 12-hour period Thunderstorms in a 2-hour period Precipitation type Visibility Conditional visibility Obstruction to vision These changes will slightly alter the format of the LAV text products because new lines will be added to the existing bulletins to accommodate the new stations. In addition, some stations might not have had guidance for all of the above elements prior to this change, and with this change, guidance will now be produced for those elements for those stations. These changes will also alter the contents of the LAMP BUFR messages because new guidance will be available.

The upgrade in the GEFS production suite includes: 1. Running the latest Global Forecast System (GFS) model with improved physics scheme GFS v9.1.0 to replace the currently used GFS v8.0 2. Increasing the horizontal resolution from T190 (about 70km) to T254 (about 50-55km) for the first 192 hours (8days) of model integration 3. Increasing vertical resolution from 28 levels to 42 levels for 0-384 hours (0-16 days) forecasts 4. Improving the ensemble initialization method by inflating the initial perturbations between Earth’s surface and 500mb. 5. Optimizing the stochastic Total Tendency Perturbation (STTP) scheme, implemented in February 2010 to represent model related uncertainty by adjusting its parameters to match the increased model resolution Due to the increase in model resolution and limitations in computational resources, the delivery of some GEFS products will be delayed. Files for the early hours (06h forecast) will experience virtually no delay. Files for the longer forecast hours may be subject to a delay of up to 20 minutes depending on the lead time. This change has been announced earlier this year in a Public Information Statement. The delivery times of the GFS and North American Ensemble Forecast System (NAEFS) products will not be affected. There will be several changes in the GEFS product data files affecting files with names pgrba/pgrbb. The GEFS products disseminated over NOAAPORT will not change in format or content. The GEFS products disseminated via the NWS and NCEP servers will have some changes in content. A small increase in the GRIB product data volumes is expected due to these changes.

Also amended to indicate that NWS will be removing the 80km, 40km native level and surface products listed below with implementation of the RAP. On or about Tuesday March 20, 2012, beginning with the 1200 Coordinated Universal Time (UTC) run, the National Centers for Environmental Prediction (NCEP) will replace the Rapid Update Cycle (RUC) with the Rapid Refresh (RAP) model. Changes include: -Covering a much larger domain, compared to the RUC, including Alaska and the Caribbean basin and almost all of North America -Introducing a new modeling framework -Installing a major upgrade to the prediction model -Modifying the data analysis and assimilation system -Matching most existing RUC products and adding new ones to cover the expanded domain. A select number of obsolete RUC files will be removed. -Introducing experimental North American Rapid Refresh Ensemble using Time Lagged (NARRE-TL) forecast. -Modifying some product output and changing the names of all directories and output filenames from *ruc* or *ruc2a* to *rap*. Details on the various changes are provided below, along with a notice about possible changes to product generation time. NWS has tried to capture all of the changes occurring with this implementation. In the event that something was overlooked, we will amend this TIN. General Framework Like the RUC, the RAP will be run 24 times per day, once for each hour. Each run will be integrated to 18 hours, and output will be available for each forecast hour. Due to the larger domain, lateral boundary conditions for the RAP will be provided by the Global Forecast System (GFS) instead of the North American Mesoscale (NAM) model as is done for the RUC. The model will be fully cycled with all fields, including snow cover, carried through to the next cycle. The model will continue to trim snow cover twice per day based on the NESDIS analysis. To prevent the model from drifting away from the synoptic truth, two 6-hour partial cycles will be initiated each day at 03z and 15z by bringing in a guess for atmospheric fields only from the GFS and then performing a series of analyses and 1-hour forecasts with the final 1-hour forecast used as the first guess for the 09 and 21z cycles. Like the RUC, the RAP has a 13 km horizontal resolution and 50 vertical levels. A sigma vertical coordinate is used in the RAP, compared to the sigma-isentropic hybrid vertical coordinate in the RUC. The pressure top of the RAP is at 10 hPa, compared to 40-70 hPa pressure top on the highest isentropic surface in the RUC. The native horizontal grid for the RAP is a rotated latitude-longitude grid. Analysis Upgrade The Gridpoint Statistical Interpolation (GSI) analysis system has been adapted for the RAP. It maintains several important components of the RUC analysis: -Cloud hydrometeor analysis -Assimilation of radar reflectivity data -Diabatic digital filter initialization Additional observations are assimilated in the RAP that are not currently assimilated in the RUC, including: -Satellite radiances, including AMSU-A and AMSU-B, similar to that done for the North American Mesoscale (NAM) model -Aircraft moisture observations from UPS and Southwest Airlines -915-MHz profiler wind observations -GOES cloud pressure/temperature from NASA Langley over full RAP domain added to NESDIS cloud data already assimilated in RUC Model Upgrade The RAP model component is a configuration of the Weather Research and Forecasting (WRF) model, using the Advanced Research WRF (ARW) core. It keeps, however, mostly RUC-like physics including: -A version of the Grell convective scheme -Thompson cloud and precipitation microphysics -Rapid Radiation Transfer Model (RRTM) longwave radiation -Goddard shortwave radiation -MYJ (Mellor-Yamada-Janjic) planetary boundary layer (PBL)/ turbulent mixing -RUC/Smirnova land-surface model. Updated versions of the cloud microphysics, Grell convection, and RUC land-surface schemes are used in the RAP over older versions used in the RUC. Output Product Changes The RUC currently generates output on pressure levels (pgrb) and native levels (bgrb) at horizontal resolutions of 13, 20 and 40 km for every forecast hour (0-18). Smaller files with near-surface data (sgrb) are generated at a smaller number of forecast hours at the same resolutions, and an 80 km data set generated for a few forecast hours is also available. The RUC output is made available to users on the NWS ftp server, the NCEP server, and a subset of the output is available on NOAAPORT. The NWS issued a Public Information Statement(PNS) on November 9, 2011 requesting comments on the proposal to remove several RUC products.

The RUC output is made available to users on the NWS ftp server, the NCEP server, and a subset of the output is available on NOAAPORT. As part of this implementation, the NWS is proposing that the following RUC data sets be removed: -All sgrb data. -80 km data. -Native level output at 40 km resolution. A public comment period on this proposal runs through December 12. Once a decision is made, this TIN will be updated to reflect the final decision. Please see the PNS referred to above for specifics about the exact files to be removed and the dissemination outlets for these files. The following new data sets will be available on the NCEP server, with output at all forecast hours: -Full domain 32-km grid (AWIPS grid 221). -11 km Alaska grid (AWIPS grid 242). To facilitate a smooth transition from the RUC to the Rapid Refresh, NCEP is making look-alike files in the RAP to mimic output provided by the RUC. Files with data on native levels (bgrb) and pressure levels (pgrb) will be provided on the same 130 (13 km) and 252 (20 km) grids currently generated by the RUC. In addition, RAP pgrb data (not bgrb) will be provided on the 236 (40 km) grid. NCEP has tried to match the fields offered by the RUC, but there are a few exceptions listed below resulting from the use of the NCEP unified post processor. When a RUC parameter is unavailable, NCEP has tried to find a similar parameter that RAP can generate but a few fields could not be matched and were eliminated. There are also situations in which the same parameter is available in the RAP as in the RUC, but the Product Definition Section (PDS) of the GRIB encoding identifies the parameter in a different way. All of these differences are documented below. Note that changes to the order of the parameters in the files are not documented. It is standard NCEP practice to change the sequence of fields in a file without documentation. Users are advised to extract records from the files by using the PDS instead of using the order of records. Also note that these look-alike files, which match the domain covered by the RUC, only cover a portion of the expanded RAP domain: 32-km full-domain files on grid 221 will be available in the RAP. No full-domain data sets will be available at any other resolution other than 32 km: 11-km files on grid 242 will be available for users wanting high-resolution RAP output over Alaska. The differences between RAP and RUC files are discussed below: BGRB (native levels): -The vertical profile of virtual potential temperature (parameter 189) in the RUC is replaced by temperature (parameter 11) in the RAP. -The vertical profile of mixing ratio (parameter 53) in the RUC is replaced by specific humidity (parameter 51) in the RAP. -The net longwave flux at the surface (parameter 112) in the RUC is replaced by the surface downward longwave flux (parameter 205) in the RAP. -The net shortwave flux at the surface (parameter 111) in the RUC is replaced by the surface downward shortwave flux (parameter 204) in the RAP. -The RAP maintains 3-hr buckets for convective and non- convective precipitation like the RUC, but it adds in 1-hr and run total buckets. -The lightning parameter (187) now has values in the RAP where 1 indicates a model prediction of an ongoing thunderstorm, and 0 is the null event. The RUC field currently contains zeros at all points. -The rate of water dripping from canopy to ground (parameter 188) is not available in the RAP. -The fields of snow temperature (parameter 239) at 5 and 10 cm are not available in the RAP. -The field of surface mixing ratio (parameter 53) and density (parameter 89) at 5 cm are eliminated. -The storm-surface and baseflow-groundwater runoff parameters are now 1-hr accumulations in the RAP, compared to the instantaneous values in the RUC. -The following new parameters are added to the bgrb files: PBL height (parameter 221), surface height (parameter 7 at surface), surface wind gust (parameter 180), skin temperature (parameter 1 at surface), friction velocity (parameter 253), and upward longwave flux at the top of the atmosphere (parameter 212 at TOA). -The "best" convective available potential energy (parameter 157) and convective inhibition (parameter 156) fields are now true values of those parameters rather than being calculated using moist static energy as in the RUC. These fields in the RAP are computed using the virtual temperature correction. PGRB (PRESSURE LEVELS): -The surface-based lifted index (parameter 131) now has the vertical coordinate defined as 101 (layer being two isobaric levels) with 500 and 1000 as the two levels. The RUC defines it as a surface field (vertical coordinate 1). This parameter is now computed using the virtual temperature correction. -The "best" lifted index (parameter 132, labeled as computed between 0 and 180 mb) replaces the best lifted index (parameter 77, labeled as computed at the surface) in the RUC. This parameter is now computed using the virtual temperature correction. -The 0-3 km storm-relative helicity field (parameter 190) is correctly labeled with vertical coordinate 106 with 3000 and 0 m as the levels in the RAP; it is a surface field in the RUC. Note that the 0-1 km helicity is correctly labeled in both the RAP and RUC. -The storm motion components (parameters 196 and 197) are correctly labeled with vertical coordinate 106 with 6000 and 0 m as the levels in the RAP; they are surface fields in the RUC. -The storm-surface and baseflow-groundwater runoff parameters are now 1-hr accumulations in the RAP, compared to the instantaneous values in the RUC. -The convective available potential energy (parameter 157) and convective inhibition (parameter 156) fields (surface-based and best) are now true values of those parameters rather than being calculated using moist static energy as in the RUC. These fields in the RAP are computed using the virtual temperature correction. -Cloud base height (with vertical coordinate 2) and cloud top height (with vertical coordinate 3) now use parameter 7 (geopotential height) in the RAP; the RUC defines them as parameter 8 (geometric distance). Also note that grid points with no defined cloud base or top use a bitmap for this field in the RAP; the RUC uses -9999 for the value. -The pressure level from which a parcel used in CAPE/CIN computations is lifted (parameter 141, vertical coordinate 116) in the RAP replaces the pressure level of maximum equivalent potential temperature (parameter 1, vertical coordinate 246) in the RUC. Both parameters are computed similarly. -The convective cloud top height field (parameter 7, vertical coordinate 243) uses -500 as a value of no cloud in the RAP; the RUC uses 0. BUFR (station time-series data) The RAP will continue to generate station time-series BUFR data in the formats of one monolithic file containing data for all stations and individual station files. The RAP, however, generates data for more stations than the RUC due to its larger domain. The RUC currently generates data for 1168 locations; The RAP will generate this data for 1447 locations. There will be no change in the format or content of the data for each station. Experimental NARRE-TL product The new experimental NARRE-TL products are constructed from a weighted blend of the 6 most current RAP and 4 North American Mesoscale (NAM) forecasts covering the 01-12 hr period. The weighting is inversely proportional to forecast length and new 01-12 hr NARRE-TL guidance is produced every hour. The parameters are geared towards aviation needs. For CONUS: http://www.emc.ncep.noaa.gov/mmb/SREF_avia/FCST/NARRE/web_site/h tml/conv.html for Alaska http://www.emc.ncep.noaa.gov/mmb/SREF_avia/FCST/NARRE_Alaska/web _site/html/conv.html In addition to these sites, this guidance will be available from the NCEP server site. File Names: The file names for RAP output will differ from the equivalent RUC files. For servers that maintain the nomenclature of the files as they are generated, the following conversions apply: For forecast cycle XX (00-23) and forecast hour HH (00-18): -ruc2.tXXz.pgrb13fHH.grib2 becomes rap.tXXz.awp130pgrbfHH (13 km) -ruc2.tXXz.pgrb20fHH.grib2 becomes rap.tXXz.awp252pgrbfHH (20 km) -ruc2.tXXz.pgrbfHH.grib2 becomes rap.tXXz.awp236pgrbfHH (40 km) -ruc2.tXXz.bgrb13fHH.grib2 becomes rap.tXXz.awp130bgrbfHH (13 km) -ruc2.tXXz.bgrb20fHH.grib2 becomes rap.tXXz.awp252bgrbfHH (20 km) Note that for analysis files, the RUC uses an "anl" suffix; the RAP will use the conventional "f00" for these files. For example, ruc2.tXXz.pgrb13anl.grib2 becomes rap.tXXz.awp130pgrbf00.grib2. The 32 km full domain files will have the naming structure rap.tXXz.awip32fHH.grib2. The 11 km Alaska files will have the naming structure rap.tXXz.awp242fHH.grib2. Product Dissemination The RUC output is currently available on NOAAPORT, and with the possible exception of the 80km products under consideration for removal, all look-alike RAP products will be available on NOAAPORT with the same WMO headers as the current RUC products. RUC output is also available on the NWS ftp server and the NCEP server. Along with the file name changes outlined above, all directories on these servers will change from ruc to rap. The RAP output will be available in the following directories: NWS FTP server: ftp://tgftp.nws.noaa.gov/SL.us008001/ST.opnl/MT.rap_CY.hh where hh is the model cycle from 00 to 23 NCEP server: http://www.ftp.ncep.noaa.gov/data/nccf/com/rap/prod ftp://ftp.ncep.noaa.gov/pub/data/nccf/com/rap/prod Product Delivery Time Changes: The RAP cycle will be initiated each hour at the same times that the RUC is currently initiated: 26 minutes past the hour for all cycles, except 00/12z which are started at 58 minutes past the hour in order to wait for raob data to become available. NCEP anticipates that output delivery times after the RAP implementation will be very similar to those from the RUC, but the precise amounts still need to come out of the final pre- implementation testing by NCEP Central Operations.
