NOTE: As of March 2021, the Unidata Program Center is transitioning away from in-house support of GEMPAK. We are encouraging interested individuals to organize a community-based maintenance team. Details about the history of and rationale behind this decision can be found in this post:

A Proposal for Community Support of GEMPAK

GEMPAK/NAWIPSGEMPAK 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). A source code tarball is available for builds on other systems.
