This page provides links to several self-contained, downloadable software products and tools which 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 AOM-GR
FORTRAN source and documentation for the 1999 and 2004 versions of
the GISS Atmosphere-Ocean Model (GR).

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