GEMPAK - Unidata Community GEMPAK 7.14.0.1 Release

This release signifies the desire for the community to make releases at a faster
cadence than verbatim tracking NCEP NAWIPS releases (#74). We will continue
to attempt to merge any upstream NCEP NAWIPS releases, but will attempt to add
additional functionality here.

Bug Fixes

  • The install4j Java vulnerability is "addressed" by simply removing the offending
    jar file content, which is generally unused by the Unidata Community (#69).
  • The release of 7.14.0 has a number of issues with included GEMPAK tables
    with Unidata modifications over-written by the NCEP NAWIPS releases (#70). There
    may still need to be some work done in this area, but things are much closer now
    to back to normal.
  • @sgdecker kindly provided fixes for a couple of edge cases (#44, #46).

Improvements

  • Developer experience improvements were made with some cleanups to the git
    repository (#78) and implementation of Github Actions for CI (#65, #57).
  • GEMPAK now supports the newly added "Super-Res" NEXRAD Level III products (#73).

GEMPAK - GEMPAK 7.5.1

Release Notes

  • Supports GOES-16/17 ABI imagery in NetCDF 4 format
  • Fixed build of program dctama

GEMPAK Support for GOES ABI NetCDF

GOES16 and GOES17 ABI products are distributed in NetCDF4 formatted files, and GEMPAK as of release 7.5.1 can now read and display these products in their native formats (it is no longer needed to convert netCDF to McIDAS area format to display in GEMPAK).

For Full Disk and CONUS sectors, GOES16 and GOES17 ABI products are sent across the Satellite Broadcast Network as tiles, each contributing to a "mosaic" of a full sector scan. The Unidata Program Center has provided an alternate data feed in which all tiles are "stitched" together (thanks to the program ldm-alchemy).

ldmd.conf

To request these stitched images, add the following request line to your ldmd.conf:

REQUEST NIMAGE "GOES" idd.unidata.ucar.edu

pqact.conf

The following pattern action

NIMAGE     ^/data/ldm/pub/native/satellite/GOES/(.*)/([^/]*)/([^/]*)/([0-9]{8})/GOES(16|17)_([^/]*)_([0-9]{8})_([0-9]{4})(..)_([^/]*).nc4
        FILE    -close  data/gempak/images/sat/\1/\2/\3/\3_\7_\8

will create files such as :

$SAT/GOES16/CONUS/Channel02/Channel02_20181227_1812
$SAT/GOES16/CONUS/Channel08/Channel08_20181227_1812
$SAT/GOES16/CONUS/Channel13/Channel13_20181227_1942

for each of the 16 ABI channels (here the environmental variable SAT = /data/ldm/gempak/images/sat/) and each available sector (e.g. CONUS above).

NMAP2 Display

The above pqact.conf entry will write images to directories in $SAT, which are then selectable in NMAP2 > New Data Source > Image

GOES16 Full Disk

GOES16 CONUS

GOES16 PRREGI

GOES16 Mesoscale-1

GOES16 Mesoscale-2

GOES17 Full Disk*

  • as seen above there is still a map projection error for GOES17 Full Disk images.

Atmosphere - Meteorological Observation and Forecast - C
Published by mjames-upc over 8 years ago

GEMPAK - GEMPAK 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.

-rw-rw-r-- root/root      7863 2015-08-04 11:30 gempak-7.2.0/Gemenviron.profile

You can remove and recreate the NAWIPS symbolic link to the new source directory:

rm NAWIPS
ln -s gempak-7.2.0 NAWIPS

Or you can overwrite an existing GEMPAK folder with gempak-7.2.0 to make use of the existing NAWIPS -> GEMPAK symbolic link.
