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. A complete list of CESM scientifically validated configurations is available for users needing to run the model in one of these configurations.
This table lists the most current supported CESM release versions.
|Supported CESM Release Versions|
includes: What's New - Science, What's New - Software, Answer-Changing Features, Supported Machines, and Known Problems
|CESM 1.1.z||Notable Improvements|
|CESM 1.0.z||Notable Improvements|
CESM X.Y.Z - CESM model release versions include three numbers separated by a dot (.) where:
Each release includes the complete collection of component model source code, documentation, and input data. For model output data, see the Experiments and Output Data section of this website.
Users should read the CESM Data Management & Distribution Plan which documents the procedures for the storage and distribution of data associated with the CESM project.
Scientific validation of the 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.
CESM 1.2.0 is in the process of adding scientically validated configurations and these will be posted on the web site as they become available.
Component sets and resolutions are backward compatible with all CESM releases. However, newer releases of the 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.
