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
messages. 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:
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.
