CCSM(Coupled Model) Releases Each release includes the complete collection of component model source code, documentation, input data. Model output data is available Release Date Description CCSM3.0 June 2004 Notable improvements. Numerous multi-century control runs have been conducted at low, medium, and high resolutions and are available to the general public for examination and analysis CCSM 2.0. 1 Oct 2002 Provides an incremental improvement over CCSM20 A number of minor problem were fixed, forcing datasets were updated, and a lower-resolution paleo version(t31/gx3v4)of the model was included CCSM 2.0 May 2002 All components have been upgraded. Target architectures were IBM SP, SGI Origin 2000, and Compaq/alpha. A multi-century control run was presented at the annual CCSM Workshop in June 2002 CSM 1. 4 July 2000 This version introduces further improvements to the code, build procedures, and run scripts. This code distribution will run on Cray machines and SGl Origin 2000 machines CSM 1.0 June 1996 This was the first public release of the CCSM software. This code and corresponding control runs were presented at the firest CSM Workshop in May 1996 Information on component models or stand-alone components Component Models Description Atmosphere(CAM) The Community Atmosphere Model( CAM)is the latest in a series of global atmosphere models developed at NCAR for the weather and climate research communities. While a version CAM serves as an atmospheric component in the CCSm framework(a coupled system), this is an alternate version that runs as a"stand alone"(uncoupled)model Sea Ice CsiM The Community Sea Ice Model(CSIM) serves as the sea ice component of CCSM. It is the esult of a community effort to develop a portable, efficient sea ice model that can be run coupled in a global climate model or uncoupled as a stand-alone ice model. It is a dynamic-thermodynamic model that includes a subgrid-scale ice thickness distribution, energy conserving thermodynamics, and elastic-viscous-plastic(EVP)dynamics
