CCSM Research Tools: CCSM1.4 Public Release

Documentation, Source Code, and Input Data

The Climate System Model (CSM) software is based on a framework that divides the complete climate system into component models connected by a coupler. Individual component models, atmosphere, land, ocean, and sea-ice, can be exchanged for alternate models, thus allowing different configurations appropriate for different applications.

CSM 1.4, released July 11, 2000, is the fourth major release of the CSM, a comprehensive coupled model of the Earth's climate system. Both active and data models are available. Standard resolutions are T31 & T42 for the atmosphere and land components, and a nominal 3x3 and 2x2 degree resolution for the sea-ice and ocean components. Other resolutions are also possible.

Download Source Code, Input Data, and Run Scripts

Directions for downloading and building CSM1.4 can be found on the CSM1.4 download page. This collection of code is meant to be compiled and run on either a Cray or a SGI Origin 2000 machine.
