Subject: Additions, Deletions, Changes to NAM And RUC (RAP)
BUFR Stations and Additional and
Removed Stations in
NCEP NAM Soundings Collectives on NOAAPORT:
Effective March 6, 2012
Effective March 6, 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.

lists. The numerical and character identifications are provided:

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.
