Amended: Changes to NCEP BUFR Products:
Effective Date January 25, 2011
Amended to announce the new implementation date. Issues that arose during testing in December
have been resolved. The implementation and associated BUFR format changes will
take place on Tuesday, January 25, 2011.
The
National Centers for Environmental Prediction (NCEP) will upgrade the software
used to create model output products in BUFR format. This upgrade will
result in the following two changes to the format of all NCEP BUFR products:
1. The
identification section of each BUFR message will
indicate the use of Version 13 of the WMO Master
Table.
NCEP BUFR products currently use Version 12.
2. An
additional empty (zero subset) BUFR message will now be
included within all files that contain BUFR table
Note
that this change does not affect Model Output Statistics (MOS) and Localized
Aviation MOS Product(LAMP) products.
Sample
NCEP BUFR products are available at:
ftp://ftp.ncep.noaa.gov/pub/data1/nccf/com/bufrlib
The
"current" directory contains the BUFR products created with the
current operational BUFR software. The "new" directory contains the
same products generated with the new BUFR software.
