This page provides links to several self-contained, downloadable software products that have been developed by GISS personnel, either for specific research purposes or for more general analytic use.
Climate Modeling
GISS GCM - Model E
Fortran 90 source and documentation for the GISS ModelE series of coupled atmosphere-ocean models. These models have been used for our contribution to the CMIP3 and CMIP5 archives of model simulation results.

GISS GCM - Model II
Fortran source and documentation for the 1980s version of the GISS global climate model, used in the NASA GISS global warming simulations described in 1988. The code is maintained and distributed by the Columbia University EdGCM project.

Exoplanets & Planetary Science
GISS GCM - ROCKE-3D
Fortran 90 source and documentation for a version of GISS modelE GCM specially adapted for planetary (non-modern-Earth) simulations.
