I found that installing the latest NCEP BUFR library in $NAWIPS/extlibs/ncepBUFR, from the link provided in the forwarded email from 8/13/13, and rebuilding NAMSND does the trick! An extra benefit is that the program no longer needs to run solely on a big-endian system (e.g., Solaris on SPARC) ... it runs fine on Linux now. Micheal, perhaps Unidata can make the necessary updates for 6.10. A new Makefile will need to be made. Per the "README_BUFRLIB" in the latest BUFRLIB package, on Linux with gfortran I needed to modify "preproc.sh" to add the "-traditional-cpp" flag when preprocessing the .F files, and also add -DUNDERSCORE and -f-no-second-underscore when compiling the .f files. _____________________________________________ Kevin Tyle, Systems Administrator Dept. of Atmospheric & Environmental Sciences University at Albany Earth Science 235, 1400 Washington Avenue Albany, NY 12222 Email: ktyle@xxxxxxxxxx Phone: 518-442-4578 _____________________________________________ ________________________________ From: Arthur A Person <aap1@xxxxxxx> Sent: Monday, September 30, 2013 4:03 PM To: Tyle, Kevin R Cc: gembud@xxxxxxxxxxxxxxxx Subject: Fwd: NAMSND and BUFR files Kevin, ________________________________ From: "Kevin R Tyle" <ktyle@xxxxxxxxxx> To: gembud@xxxxxxxxxxxxxxxx Cc: person@xxxxxxxxxxxxx Sent: Monday, September 30, 2013 10:45:09 AM Subject: NAMSND and BUFR files 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. No, we're not using NAMSND to decode them... we're using an ancient NCEP code to dump the BUFR files and then an in-house developed decoder. As far as I know, the GFS BUFKIT files still work. Yes, it looks like it's still working, and I've had no complaints. It looks like the blocking/deblocking business has to do with whether the BUFR file had its records written in a fortran record style with fortran control words. I'm guessing the files we use are pure unblocked BUFR sounding files (e.g. from http://weather.noaa.gov/pub/SL.us008001/ST.opnl/MT.gfs_CY.12/RD.20130930/PT.sndn_DF.buf/) and therefore are not affected by the change.

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.
