On this page we list information about GAMAP, the Global Atmospheric Model Analysis Package.



  • is a self-contained, consistent, and user-friendly software package for reading and visualizing output from chemical tracer models (CTM's)
  • consists of a suite of routines written in IDL (Interactive Data Language)
  • makes extensive use of IDL's powerful plotting features
  • can produce line plots, 2D plots, 2D animations, or 3D isocontour surface plots
  • can read 2D, 3D or 4D data blocks
  • can read output from the GEOS–Chem, GISS and FSU model families
  • can be easily customized to keep pace with ongoing model development
  • can be installed on any platform that supports IDL, thus ensuring a high degree of portability
  • can be coupled with the ION (IDL on the Net) interface to create interactive plots which can be served to a web page
  • can read data from ASCII, binary, netCDF (including COARDS conventions!), and HDF–EOS file formats
  • contains helper routines to read from / write to various file formats

The main GAMAP program contains a user-friendly, menu-driven interface; however, users may also call GAMAP subroutines independently of the main program. This makes it possible to embed GAMAP routines within existing IDL code.
