This release merges upstream NCEP NAWIPS 7.15.0, whose CHANGELOG includes:

  • Bug fixes and other issue resolutions.
  • Cumulative revisions to NAWIPS data tables to support maps/bounds,
    surface stations, tropical, and other routine periodic updates.
  • Integration of compiler, and certain changes required to support the
    WCOSS supercomputer and RHEL 8 Operating System transition projects.
  • Updates to Volcanic Ash Advisory user interface to support the NESDIS
    Satellite Analysis Branch.

This release also includes the following GEMPAK Community changes:

  • More dynamic setting of NAWIPS environment variable on bash (#85).
  • Update MRMS Grib Tables to v12.1 (#89).
  • Continued cleanup of bad previous merges that overwrote Unidata
    local table modifications.

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).

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.
