Model Releases

View all of the releases for the models we offer below or you can view the current releases.

Community Earth System Model (CESM)

The Community Earth System Model (CESM) is a fully-coupled, global climate model that provides state-of-the-art computer simulations of the Earth's past, present, and future climate states.

The supported CESM development release is CESM 2.2.2 and the supported CESM production release is CESM 2.1.5

Note: The CESM2.2.z release is not a scientifically supported version; that is, we do not have any long simulations with this model version yet. In most cases, users should continue to use the CESM2.1.z series for their science and especially for CMIP6-related simulations.

Community Atmosphere Model (CAM)

The Community Atmosphere Model (CAM) is the latest in a series of global atmosphere models developed primarily at the National Center for Atmospheric Research (NCAR)

Community Land Model (CLM)

The Community Land Model is the land model for the Community Earth System Model (CESM)
