GEMPAK 5.6.J release
Final release engineering of GEMPAK 5.6.J is underway (combined release incorporating 5.6.I).
This release will add support for the FreeBSD operating system. Additionally, the release has
been ported to Mac OSX (Darwin using openMotif), though this operating system does not yet provide
the message queue funtionality required for command line GEMPAK programs (GUIs and decoders have been tested).
When message queue support is integrated into Darwin (stubs are already present), GEMPAK should be
fully functional. See the
new feature summary
for more information on updated features in this release.
GEMPAK Training Workshop
The UPC is currently planning for the 2003 package training workshops. The UCAR Corporate Training Center
has been utilized the past two years, and the GEMPAK workshop has been fully subscribed. The training center
will be relocating to new space at the Center Green complex this year, and we are currently waiting
information regarding the facility availability. A fall workshop may be held this year (the past 3
workshops have been held during the summer months).
GEMPAK web portal transition
Online user registration/download available through Unidata portal site. Migration of GEMPAK web pages from the old web server to the new web server is in progress. Approximately 201 unique domains have downloaded GEMPAK 5.6.H (Through Feb 18, 2003).
GEMPAK 5.6.G & GEMPAK 5.6.H Releases
GEMPAK 5.6.H was released to the Unidata community on September 16, 2002. Due to the time necessary to prepare and conduct the GEMPAK user training workshop at the end of July, the releases of 5.6.G and 5.6.H were combined into a single release to the Unidata community.
This is the first version of GEMPAK to support 16/24 bit displays, meaning that sites are no longer limited to running their X server with a default visual in 8 bit pseudocolor mode.
NEXRAD composites are being created and inserted into FNEXRAD datastream
National and Regional radar composites are being created using GDRADR and inserted into the FNEXRAD data stream as GRIB products. The regional composite is designed to be relocatable floater as weather conditions warrant. GRIB products are used so that the products are independent of the display package. The grid products are most flexible for use in computations with other data fields such as RUC temperature grids as shown in the preciptation type mosaic. The mosiac product is approximately 80 Kbytes in GRIB format.
A high resolution 1km mosaic is also being created as a 4800x3000 point GINI format image. The image can be compressed to about 1 Mbyte for transmission in the FNEXRAD datastream and can be easily subsetted by an ADDE server. Uncompressed, the full GINI image is 14.4Mbytes.
Web pages and documentation for GEMPAK 5.6 have been updated.
COMET case studies available via CODIAC
COMET case studies are compatible with the GEMPAK/NAWIPS environment, and are being made available via the CODIAC system.
GEMPAK workshop and tutorial online
All the handouts/displays for the GEMPAK workshop are been made available through the GEMPAK web page tutorial. Included in the presentation are numerous sample exercises and output samples. This format of presentation allows workshop participants to be able to review or utilize any of the material at their home institution. The tutorial is updated as new features dictate.
