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. 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). 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. The offline chemical transport model has been described as 'very efficient'.
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.

Famous quotes containing the words community, climate, system and/or model:
“What I wanted was to create thoughtful citizens—people who believed they could live interesting lives and be productive and socially useful. So I tried to create a community of children and adults where the adults shared and respected the children’s lives.”
—Deborah Meier (b. 1931)
“Then climate is a great impediment to idle persons; we often resolve to give up the care of the weather, but still we regard the clouds and the rain.”
—Ralph Waldo Emerson (1803–1882)
“As long as learning is connected with earning, as long as certain jobs can only be reached through exams, so long must we take this examination system seriously. If another ladder to employment was contrived, much so-called education would disappear, and no one would be a penny the stupider.”
—E.M. (Edward Morgan)
“When you model yourself on people, you should try to resemble their good sides.”
—Molière [Jean Baptiste Poquelin] (1622–1673)
