The purpose of this project is to establish the climate record of four versions of the National Center for Atmospheric Research (NCAR) Community Climate Model (CCM). Since the public release of the initial version of the CCM (CCM0) in 1982, advances in our modeling of the climate system have led to the release of CCM1 in 1987 and CCM2 in 1992. Several other versions of the CCM have also been developed at NCAR, two examples of which are the Global Environmental and Ecological Simulation of Interactive Systems (GENESIS) model and the Climate Sensitivity and Carbon Dioxide (CSCO2) model. This study documents and compares the mean January and July climates of CSCO2, GENESIS, and standard versions of CCM1 and CCM2. Each model was integrated for 10 years with a horizontal spectral resolution of rhomboidal 15 (R15), including a low-resolution R15 version of CCM2.
