CESM Models | CESM Supported Releases
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
scientifically validated configurations is available
for users needing to run the model in one of these
CESM X.Y.Z - CESM model release versions include three numbers separated by a dot (.) where:
- X - corresponds to the major release number indicating significant science changes.
- Y - corresponds to the addition of new infrastructure and new science capabilities for targeted components.
- Z - corresponds to release bug fixes and machine updates.
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
Data Management & Distribution Plan which
documents the procedures for the storage and
distribution of data associated with the CESM
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
CESM 2.0 is in the process of adding scientically
validated configurations and these will be posted on the
web site as they become available.
