NCEP BUFR FILE STRUCTURE


with emphasis on embedded BUFR table (A,B,D) messages



Latest Revision - 04/02/2008




Every BUFR file that is presented to the NCEP BUFRLIB software, either for input (reading/decoding) or output (writing/encoding) purposes, must have a BUFR tables (A, B, D) file associated with it.  These tables may be defined within a separate ASCII text file (see Description and Format of BUFR Tables for more information) or, in the case of an existing BUFR file, may be embedded within the first few BUFR messages of the file itself.  When an NCEP "flavored" BUFR file is created for the first time, the BUFR tables are usually read from an external ASCII text file (although it is also possible to read the tables from table messages that are embedded within another BUFR file).  The tables will then be written into the first few BUFR messages at the top of the new file (using as many messages as needed to encode the complete set of tables).  This "feature" allows all NCEP BUFR files to be self-describing, i.e., anyone using the NCEP BUFRLIB routines can read an NCEP BUFR file without the need for external files containing BUFR tables A, B, D.

This document describes in detail the content of these embedded BUFR messages containing the BUFR tables, as they appear in NCEP BUFR files.  It then follows with a less-detailed summary of the contents of the actual BUFR data messages which follow.  The example shown here is for the NCEP BUFR tables associated with Table A (message) type 2 [vertical soundings (other than satellite)] as it appeared on 04/01/2008 (although the basic layout of the BUFR table messages is the same for all Table A types). These tables are embedded in the top messages of the NCEP "adpupa" BUFR data dump file.  This file contains upper-air profile data for rawinsonde, dropwinsonde, PIBAL, ozonesonde, wind and spectral moment profiler, NEXRAD VAD wind, and RASS temperature reports.

Click here to view the ASCII text file (called /nwprod/fix/bufrtab.002 on the NCEP CCS machines) which is read in by the BUFRLIB software.

This text file will require three 10,000 byte BUFR messages in order to hold all of its information. These will be the first three messages in the "adpupa" BUFR data dump file.  The BUFR messages containing the tables A, B, D are in Table A (message) type 11.

1 - Since the length of an NCEP BUFR message has an upper limit (the default being 10,000 bytes, as used in the "adpupa" BUFR data dump files, but with a maximum of 2.5 million bytes), this replication factor may be less than the actual number of lines in this section of the ASCII text file.  In this case, the next BUFR message will resume at point left off in the replication here, and it will continue the replication until all lines in this section of the ASCII text file have been parsed out.
