GEMPAK/NAWIPS

GEMPAK/NAWIPS GEMPAK is an analysis, display, and product generation package for meteorological data. Originally developed by NCEP for use by the National Centers (SPC, TPC, AWC, HPC, OPC, SWPC, etc.) in producing operational forecast and analysis products, UCAR's Unidata Program Center releases and support a non-operational version of GEMPAK for use in research and education.

GEMPAK is available as a pre-built binary for 64-bit Linux systems (Red Hat, CentOS, Fedora Core) and for Mac OS X. A source code tarball is available for builds on other systems.

GEMPAK Migration to AWIPS II

The National Weather Service (NWS) announced plans in 2007 to cease development of GEMPAK/NAWIPS in August 2008 and proceed with a migration of the functionality of that package to the new AWIPS II environment. Unidata has created a page to provide information to the Unidata community on the migration.
