Subject: 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:
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.
