Subject: Additions and Changes to the NAM and RAP BUFR
Soundings Effective December 17, 2013
Effective on or about Tuesday, December 17, 2013, 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 Binary Universal Form for the
Representation (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 NAM model
BUFR sounding collectives disseminated on NOAAPORT.
The new stations are listed in Table 1. The stations being
changed are listed in Table 2. No stations are being
removed. This set of changes to the NAM and RAP will correspond
with the implementation of version 2 of the RAP, currently
scheduled for December 17.
The high-resolution 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 nests BUFR output as well.
In this implementation, all of the modified sites are in the
CONUS nest output. All of the new stations are in the CONUS nest
output, except for station 000367 that will appear in the Puerto
Rico nest output.
The changes to the BUFR station lists will result in no changes
to the WMO headers of the NOAAPORT NAM soundings collectives. The
headers listed in Table 3 are the current headers and NCEP will
continue to use them. 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 appear in Table 4.
The Short-Range Ensemble Forecast system (SREF) station list will
be updated in early 2014. The changes to that list will be
detailed in an upcoming SREF TIN.

Table 2: Changes to existing sites being made to the NAM and RAP
BUFR lists. The numerical and character identifications are
provided:
-Station 000037 (near Carroll, IA) will moved from 42.00 N,
95.00 W to 42.04 N, 94.79 W and will now be known as Carroll,
IA. This puts the BUFR point at the local airport instead of the
current rural location.
-Station 000050 (near Albia, IA) will move from 40.90 N, 92.8 W
to 42.11 N, 92.92 W and will now be known as Marshalltown, IA.
The character identifier will change from AIA to MAR.
-Station 000080 (Redding, IA) will moved from 40.69 N, 94.47 W to
41.02 N, 94.36 W and will be known as Creston, IA. The
character identifier will changed from RDD to CSQ.
- Station 724754 (Saint George AWOS, UT) will move from 37.08 N,
113.6 W to 37.04N, 113.5W to match the new location of the
airport.
