CESM2 Scientifically Validated Configurations

Important

You should use the most recent version of the model that is available unless you are trying to replicate previous results or create a branch run from a previous experiment.

Scientific validation of CESM consists of a multi-decadal model run of the given component set at the target resolution, followed by scientific review of the model output diagnostics. All scientifically supported component sets are also accompanied by diagnostic and model output data.

Component sets and resolutions are backward compatible with all CESM releases. However, newer releases of CESM allow for additional compsets, resolutions and machines.

The DiscussCESM Forums bulletin board can also provide specific recommendations from the CESM community regarding which release of the model to use for your specific requirements.
