Subject: Amended: Addition of HIRESW Products to NOAAPORT:

         Scheduled for November 8, 2011.

 

Amended to schedule the implementation date to activate these products on NOAAPORT/Satellite Broadcast Network (SBN) expansion on November 8, 2011.

 

On Tuesday, November 8, 2011, the National Centers for Environmental Prediction (NCEP) will begin disseminating output from the High-Resolution Window Forecast System (HIRESW) on NOAAPORT and SBN. 

 

HIRESW includes runs of the Weather Research and Forecast (WRF) version 3.2 of the Advanced Research WRF (ARW) and the Nonhydrostatic Mesoscale Model (NMM).  These runs are made over
6 domains covering the contiguous United States , Alaska , Hawaii , Puerto Rico and Guam . The HIRESW generates gridded output in GRIB2 format for 5km grids for each domain.

 

Below is the run schedule and the associated domains:

 

  0000 UTC: Eastern US, Hawaii and Guam

  0600 UTC: Western US and Puerto Rico

  1200 UTC: Eastern US, Hawaii and Guam

  1800 UTC: Alaska and Puerto Rico

 

These HIRESW runs are cancelled on the NCEP operational supercomputer when hurricane models are running during the tropical season.

 

The HIRESW provides detailed forecasts of low-level temperatures and winds, and increased structure in precipitation forecasts due to a lack of parameterized convection.  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 November 8th; however, the data will not be displayable in the Advanced Weather Interactive Processing System (AWIPS) until future modifications are made.
