CESM Models

CESM1.0: Scientifically Supported Model Configurations


CESM1 has the flexibility to create "out-of-the-box" cases with many different combinations of component models, grids, and model settings. Although not all combinations have been validated scientifically, they are provided with the CESM1 release in order to benefit the CESM community. A CESM1 component set ("compset") has been scientifically validated for a given model resolution only after it has undergone a climate validation. The climate-validation process consists of a multi-decadal model run of the given compset, at the given resolution, followed by the scientific review of the model output diagnostics. All scientifically supported component sets are also accompanied by diagnostic and model output data.

To obtain a listing of all supported out-of-the-box component sets and resolution combinations, regardless of whether they have been scientifically validated, issue the create_newcase command with the option "-list". For more information regarding alternative component configurations, please refer to the individual component web pages at http://www.cesm.ucar.edu/models/cesm1.0.
