The Community Climate System Model (CCSM) is a coupled Global Climate Model developed by the University Corporation for Atmospheric Research (UCAR) with funding from the National Science Foundation, Department of Energy, and NASA.[1] The coupled components include an atmospheric model (Community Atmosphere Model), a land-surface model (Community Land Model), an ocean model (Parallel Ocean Program), and a sea ice model (Community Sea Ice Model).[2] CCSM is maintained by the National Center for Atmospheric Research.

The software design of CCSM is based around the notion of a physical/dynamical component of the climate system, and as a freely available community model is designed to work on a variety of machine architectures powerful enough to run the model.[3] The offline chemical transport model has been described as 'very efficient'.[4]

The model itself is divided into four component models (land, sea-ice, ocean and atmosphere) connected by a coupler, which exchanges information with each of the component models. It has been suggested by NCAR themselves that because of this, CCSM cannot be considered a single climate model, but rather a framework for building and testing various climate models.[5]
