Software Tools

This page provides links to various 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 a 2004 version of the new GISS series of coupled atmosphere-ocean models. It includes a complete rewrite of the GISS Model II' physics with greater flexibility and more options, such as better representations of the stratosphere, tracer components and various ocean models.

GISS GCM - Model AOM-GR
FORTRAN source and documentation for the 1999 and 2004 versions of the GISS Atmosphere-Ocean Model (GR).
+ Go to Website

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.

Planetary Science

Mars24
Cross-platform Java applet and application which calculate the solar and mean time for any location on the planet Mars, presenting the data as digital readouts and in "sunclock" format.
