The majority of grib1 data sets will no longer be populated after that date. Equivalent grib2 data sets are now available on the NCEP and NWS ftp servers The exceptions to the conversion are listed below with their appropriate directories and filenames. No other GRIB1 datasets will continue to be populated. If you would like to continue using data in GRIB1 format, NCEP Central Operations maintains the GRIB2 to GRIB1 conversion utility cnvgrib which can help through this transition. Documentation and source code is available on the.

If a grib2 data set is not available, please inform the PMB Data Flow Helpdesk at: NCEP.PMB.Dataflow@noaa.gov Please direct all questions concerning the software codes to the NCO PMB Dataflow Helpdesk: NCEP.PMB.Dataflow@noaa.gov Below are tables describing GRIB1 model output files and the GRIB2 equivalents available on tgftp.ncep.noaa.gov and ftpprd.ncep.noaa.gov. NWS FTP SERVER (tgftp.nws.noaa.gov) ftp://tgftp.nws.noaa.gov/SL.us008001/ST.opnl/ GRIB2 file names on the NWS ftp server will remain the same as the GRIB1 file names, but the GRIB2 files are stored in new uniquely named subdirectories.

However, the GFS 1.0 deg files are an exception; the GRIB2 version will be named fh.HHHHtl.pressgr.1p0deg instead of fh.HHHHtl.pressgr.onedeg. This is to improve continuity of the names of GFS model output for all resolutions (0.5, 1.0, and 2.5 deg).
