CESM Models

CESM1.0 Public Release

About CESM 1.0

The Community Earth System Model (CESM) is a coupled climate model for simulating the earth's climate system. Composed of four separate models simultaneously simulating the earth's atmosphere, ocean, land surface and sea-ice, and one central coupler component, the CESM allows researchers to conduct fundamental research into the earth's past, present and future climate states. CCSM4.0 is a subset of CESM1.0. All CCSM4.0 compsets and resolutions are also found in CESM1.0.z.

Model Input Data

The input data necessary to run all supported component sets is made available from a public Subversion input data repository. Note that the inputdata repository has much more data in it than you need to run CESM1.0 ---- DO NOT attempt to svn checkout the whole input data repository. The CESM1.0 User's Guide explains how to obtain the subset of input data required for your needs.

Performance and Load Balancing Data

The CESM1 Timing Table provides performance data for machine hardware and input from the user community.

The CESM1.0.5 Timing Table provides performance data for yellowstone.
