Subject:  Amended: Additions, Deletions, Changes to NAM and RUC

         (RAP) BUFR Stations and Additional and Removed Stations

          in NCEP NAM Soundings Collectives on NOAAPORT:

          Effective date set for May 1, 2012.

Amended to set the implementation date for Tuesday May 1, 2012.  Users are cautioned that if a Critical Weather Day (CWD) designation is in effect on May 1, this implementation will be delayed until the conclusion of CWD.  You can monitor the CWD status at the following webpage:

http://www.nco.ncep.noaa.gov/pmb/cwd/

Effective on Tuesday, May 1, 2012, beginning with the 1200 Coordinated Universal Time (UTC) model distribution, the National Centers for Environmental Prediction (NCEP) will modify the list of stations for which BUFR data are generated for both the North American Mesoscale (NAM) and Rapid Refresh (RAP) models.  The changes will also modify the lists of stations in the North American Mesoscale (NAM) model BUFR sounding collectives disseminated on NOAAPORT.

For the NAM and RAP lists, the new stations are listed in Table 1 and the stations being removed are listed in Table 2. This change corresponds with the implementation of the Rapid Refresh (RAP) to replace the Rapid Update Cycle (RUC).

The NAM and RUC have always used the same station list, but many of the stations fall outside of the RUC domain and are not used by the model. The larger RAP domain will allow data for many more of the NAM stations to be used in the RAP output.

The lists below do not cover existing stations in the list that are outside of the RUC domain but inside the RAP domain. It deals only with actual changes to the list itself. Also note that the NAM nests use the same station list as the parent 12 km NAM, so any changes to the list involving locations within a particular nest impact that nest’s BUFR output as well.

000620  C20   Canada/Great Lakes

000621  C21   Canada/Great Lakes

072434  STL   St. Louis MO

The following changes are being made to the station lists:

-Station 000020 (nr. Watertown, SD) is moved from  44.80 N, 96.70 W TO 45.80 N, 97.45 W and will now be known as (Marshall County RAWS).  The character identification is changed from WTT to MRLS.

-Station 727790 (KGPI) now represents Glacier Park Intl instead of Kalispell/Glacier.  There is no change to the numerical or character identification.

-Station 000057 (Lewis Range of Rockies, MT) is moved from 48.00 N, 113.00 W to 48.32N, 113.35 W and will now be known as Marias Pass, MT.  The character identification is changed from LRR TO MRP.

-Station 000617 (Northern Rockies, MT) is moved from 46.00 N, 114.00 W to 46.25 N, 114.15 W and will now be known as Hamilton MT.  The character identification is changed from C17 to HMM.

The changes to the BUFR station lists will result in no changes to the WMO headers of the NOAAPORT soundings collectives.  The headers listed in Table 3, below, are used today and these headers will continue to be used.  There will also be no change to the BUFR format of the products except that new stations will be included in the collectives.  The new stations as well as those being eliminated appear in Table 4, below.
