Subject: Amended: Changes to NCEP BUFR Products:
Effective Date Postponed Indefinitely
Amended to postpone this implementation until further notice.
Some issues arose during testing that must be corrected. We
anticipate implementation in January or February and will issue
a new Technical Implementation Notice (TIN) when a new
implementation date has been determined.
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.
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.
