What grids and model resolutions are scientifically validated in CCSM2?
The CCSM2.0 release officially supported only one resolution, referred to as “T42_gx1v3”, and one configuration, fully active (B) with respect to scientific results. This combination was used in the CCSM2.0 Control Run and is the default configuration in the test.a1 case. The CCSM2.0.1 release supports a second, coarser resolution, “T31_gx3v4” version of the fully active coupled model. “T31” and “T42” are short-hand references to the resolution of the atmosphere and land models; “gx1v3” and “gx3v4” are short-hand references to the resolution of the ocean and ice models. In addition to these two scientifically validated configurations, a number of other configurations are available for scientific testing and research.
