CESM Models

CCSM Research Tools: CCSM2.0.1 updates relative to CCSM2.0


Grids and Model Resolutions

New Coarse-Resolution "Paleo" Resolution Supported in CCSM2.0.1

The CCSM2.0 release officially supported only one resolution, referred to as "T42_gx1v3," which was used in the CCSM2.0 Control Run. The CCSM2.0.1 release supports a second, coarser resolution, "T31_gx3v4," which has been validated in a paleo control run. A sample setup for the paleo run can be found in the CCSM2.0.1 release, in the scripts/test.a2 directory. [Return to Contents]

Obsolete Grid Eliminated from CCSM2.0.1

All references to the older, unsupported coarse resolution, T31_gx3, which was never scientifically validated, have been eliminated from CCSM2.0.1

Description of Supported Grid Resolutions

Please refer to the CCSM2.0.1 FAQ page for a discussion on the specifics of the various model grids and resolutions.

Data Models
