GEMPAK Download

GEMPAK is an analysis, display, and product generation package for meteorological data. It is used at National Centers for producing operational forecast and analysis products. GEMPAK consists of a large compilation of individual programs which provide data access, computation and display capabilities.

GEMPAK can be built from source for a number of operating systems and with different sets of C and Fortran compilers. Open Motif and a host of X libraries are required in order to build from source. See the GEMPAK Installation page for the source code build walk-through and library requirements.

Latest Release: GEMPAK 7.3.2

  • dcgrib(1) support for NOAAport NAM212.

Binary RPMs are provided for three common systems (x86_64 linux64, i386 linux, Solaris 5.10 x86). RPMs have package requirements similar to the libraries needed by a source code build (such as libXp, libXt, libXext, etc.).
