CCSM1.0 Public Release
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.
CSM1.0, release June 6, 1996, is the first generation of the Climate System Model, a comprehensive coupled model of the Earth's climate system. In this first release, the atmosphere & land models (CCM3.0 & LSM 1.0) are designed to be run at T42 resolution and the ocean & ice models (NCOM 1.1 & CSIM 0.9) are designed to be run at a nominal 2x2 degree resolution. This initial release is only intended to be run on the NCAR CSL Crays (antero, aztec or piaute). Future releases will have more flexibility with respect to the choice of models, grid resolution, and machine portability.
This model and the resulting science are documented in a special issue of the Journal of Climate, June 1998.

CESM Project
The Community Earth System Model (CESM) is a fully-coupled, global climate model that provides state-of-the-art computer simulations of the Earth's past, present, and future climate states.
CESM is sponsored by the National Science Foundation (NSF) and the U.S. Department of Energy (DOE). Administration of the CESM is maintained by the Climate and Global Dynamics Laboratory (CGD) at the National Center for Atmospheric Research (NCAR).
