GEMPAK 7.3.1 is available as source code, 64-bit Linux binaries, and an OS
X binary tarball. The most significant updates in this release are to
GEMPAK's Python scripts which retrieve data from an AWIPS EDEX server.
7.3.1 binary and source code releases are available at
http://www.unidata.ucar.edu/downloads/gempak/
https://github.com/Unidata/gempak/releases
I have packaged both a standard binary and a version built against Python
2.7 for use with the python-awips package (see:
http://python-awips.readthedocs.io). Please consult the updated install
instructions at http://www.unidata.ucar.edu/software/gempak/doc/install.html
for more information.
How to retrieve AWIPS data with GEMPAK?
If you have installed gempak-python and python-awips, or built GEMPAK from
source against python 2.7:
- Set/change the EDEX server defined in Gemenviron.profile/Gemenviron
(default is edex-cloud.unidata.ucar.edu)
- Ensure that libpython2.7.so* is found (e.g. "ldd $OS_BIN/gdinfo")
- Entries in datatype.tbl are used to define AWIPS grid names
grep ^A2 $GEMTBL/config/datatype.tbl
A2METAR AWIPSDB metar.xml
A2SYNOP AWIPSDB synop.xml
A2UAIR AWIPSDB uair.xml
A2GFS AWIPSDB gfs.xml
A2GFS20 AWIPSDB gfs20.xml
A2GFS80 AWIPSDB gfs80.xml
A2RAP AWIPSDB rap.xml
A2NAM AWIPSDB nam.xml
A2NamDNG AWIPSDB namdng.xml
A2NAVGEM AWIPSDB navgem.xml
A2DGEX AWIPSDB dgex.xml
A2HRRR AWIPSDB hrrr.xml
A2CMC AWIPSDB cmc.xml
A2ECMWF AWIPSDB ecmwf.xml
A2MRMS AWIPSDB mrms.xml
A2RTMA AWIPSDB rtma.xml
A2URMA AWIPSDB urma.xml
- These xml files (e.g. gfs20.xml) are found in $GEMTBL/data-access/ and
each defines the AWIPS/EDEX grid name used (e.g. dbkey="GFS20")
- An example in GDINFO:
GDFILE = A2GFS20
LSTALL = YES
OUTPUT = t
GDATTIM = last
GLEVEL = 500
GVCORD = pres
GFUNC = all
