Hi all,

Since NCEP transitioned to WCOSS this past July, we are no longer able to 
decode GFS BUFR soundings with the GEMPAK program NAMSND.  Has anyone been able 
to make modifications so that these files can again be read?  Curiously, things 
still work when processing NAM BUFR soundings.

Art, I'm specifically cc'ing you here, since I believe PSU uses the NAMSND 
program to generate output for BufKit sounding files, which look to be produced 
using SNLIST.  As far as I know, the GFS BUFKIT files still work.

Cheers,

Kevin

Subject: [Wrf-news] New BUFR format from NCEP WCOSS implementation

Dear GSI users,

Please note the community tool (ssrc) we provided for converting the NCEP BUFR 
files from Big-Endian to Little_Endian is no longer working for the new NCEP 
BUFR files after NCEP operation system went alive on WCOSS system on July 25th.

Since the July 25th, all NCEP BUFR files are unblocked files instead of 
blocked. Please see the explanations below from NCEP:

  *   Blocked/Unblocked BUFR
-All BUFR files created on WCOSS are now unblocked. This decision was made back 
in September as a result of the Endianess changes on WCOSS (Little-Endian on 
WCOSS vs. Big-Endian on CCS) and its affect on the blocking control words. 
Users are recommended to recompile their codes to link to the latest NCEP 
BUFRLIB which can read unblocked BUFR files found 
here<http://www.nco.ncep.noaa.gov/sib/decoders/BUFRLIB/>


To use the NCEP BUFR files after July 25th, please update the BUFRLIB or use 
comGSIv3.2, which includes the new BUFRLIB. The new BUFRLIB can automatically 
handle both endian files. So, no converting needed. The new BUFRLIB also works 
well with the old NCEP BUFR files without converting.

Thanks,

DTC DA Team,
