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. 73 unique domains have downloaded GEMPAK 5.6.H (Through Oct 3).
The GEMPAK training workshop was held July 29-31, 2002
in the UCAR corporate training facilities in the Pearl St.
complex. This facility can accomodate a greater number of attendees than is
possible in the Unidata conference room. A total of 28 registrations were
received for the 2002 GEMPAK workshop. The GEMPAK workshop covered
the latest release (GEMPAK 5.6.G).
Users can now register online to become a licensed Unidata site and download GEMPAK.
This process eliminates the paper license process and the need to distribute FTP passwords.
Each user creates their own login and password. The user registration is part of the
Unidata portal development.
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.
GEMPAK Training Workshops
Online user registration/download now available through Unidata web portal
NEXRAD composites are being created and inserted into FNEXRAD datastream

See May 2002 status report for past information.
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.
