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 nestís 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.
