GAMAP tips and tricks

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

Overview

GAMAP

• 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.
