GEMPAK 7.3.0 Released

GEMPAK 7.3.0 is now available from Unidata.

Source, tables, external libraries, ascii maps, and a Linux64 binary are available at http://www.unidata.ucar.edu/downloads/gempak/index.jsp

This release can also be directly download from github at https://github.com/Unidata/gempak/releases/tag/v7.3.0

  • Added GFS20 (GFS215) to tables and LDM file pqact.gempak_decoders_grid

  • Added a fix for dcwarn, dcwatch, and other decoders which would write empty files when build with gfortran 4.6+

  • A new parameter G2CONV has been added to GDGRIB2 to allow bulk processing of the GEMPAK parameters. A table that contains multiple entries of input parameters to convert to a grib2 file can be configured for processing. A typical entry in the configuration table would look like:

      GDFILE=$MODEL/gfs/gfs_0p25_2015113000f000 
      GBFILE=gfs_20151193000f000.grib2 
      GFUNC=tmpk
      GDATTIM=f00
      GLEVEL=500
      GVCORD=pres 
      PROJ=ced 
      GRDAREA=90;0;-90;-359.75 
      KXKY=1440;721 
      CPYFIL=
      G2TBLS=
      G2IS=0;2
      G2IDS=7;0;2;;0;0;0
      G2PDT=0|2;10;;;110;;;;;100;0;27500;255;0;0
      GRDRT=|4
      WHOHDR=
    

    Where the input parameters are defined in GEMPAK document, $GEMPAK/help/hlx.

  • Updated volcano table to version 4.4.0. The version can be accessed from http://volcano.si.edu/projects/vaac-data/.

  • Fixed problems in prob2cat that created erroneous displays of the categorical graphics for convective output.

  • Modified DCXMOS so that it is no longer use the climatology data provided by GEMPAK baseline. The data is over 15 years old and has never been updated. The GFS MOS reports contain an updated climatology column of data that is sufficient for the WPC forecasters. Updated the GFS MOS station table based on locations in an MDL table.

  • Baselined three new scripts, usall, islands and water, under $GEMPAK/utilities/tca2xml, which are run by users from command line to produce the TCA configuration files for CAVE. The output of each script should be redirected to the corresponding xml file names: CoastBreakpoints.xml, IslandBreakpoints.xml, WaterBreakpoints.xml.

      usall tcabkptlz.tbl > CoastBreakpoints.xml
      islands tcabkptlz.tbl > IslandBreakpoints.xml
      water tcabkptlz.tbl > WaterBreakpoints.xml
    

    The resulting config files will be copied to PGEN localization folder, gov.noaa.nws.ncep.ui.pgen/localization/ncep/pgen/

  • Updated warning decoder to handle the flash flood scenario that appears more than five sections in a flash flood warning file.

  • Fixed NAGRIB2 analysis grid, e.g., RTMA, GDATTIM to be set in a format of YYMMDD/HHHH. Before this fix, if grib(1) is converted to grib2 and then run nagrib2, GDATTIM would be incorrectly set as YYMMDD/HHHHF000.

  • Updated lightning decoder (ltgdecode) to handle the two new encrypted lightning data feeds from Vaisala and Earth Network Inc (ENI) distributed through the SFUS41 header on NOAAPORT, starting from 1630Z Nov 12, 2015 (see TIN 15-47 from http://www.nws.noaa.gov/os/notification/tin15-vaisala_lightning.htm). Lightning data are written to the files in the same manner so displays are seamless.

  • Fixed negative grid resolution (dx) when running GDGRIB2 in converting GEMPAK grid to grib2. It happened in two scenarios: (1) rlon1 > 0 and rlon2 = 0.0, i.e., eastern hemisphere (2) rlon1 < 0. && rlon2 < 0. && rlon1 > rlon2. Before the fix, negative grid increment would also show up.

  • Updated county names, fire weather forecast zones, marine county maps, bounds tables.
