Subject:  Amended: Changes to NCEP BUFR Products:

          Effective December 14, 2010


Amended to remove references to Model Output Statistics (MOS) and Localized Aviation MOS Product (LAMP) products.  This change will not affect the format of MOS and LAMP BUFR products.


Effective Tuesday, December 14, 2010, beginning with the 1200 Coordinated Universal Time (UTC) run, 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
  These empty messages are recognizable as having
   a data category value of 11 within the identification
   section of the message.


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.
