CESM Models

CAM 3.1 Download

 

Requirements

To run CAM 3.1 you will need to download:

  • a source code distribution,
  • the resolution indedependent datasets, and
  • at least one of the resolution specific datasets.

Please note that the single column model (SCAM) needs some T42 datasets, so you will need to download those to run SCAM. The only supported CAM resolutions are T31, T42, and T85 for the spectral dynamical cores, and 2x2.5 for the finite volume dynamical core. We provide datasets to facilitate experimenting with the model at other resolutions, but make no comment about the climate produced or even the ability to make long runs at unsupported resolutions.

Utilities and surface datasets

The following utilities are provided for consideration by users who wish to manipulate CAM input files. They are provided as is, with no support. There is virtually no chance that they will work 'out of the box', but the code may provide some insight into what needs to be done to prepare files for CAM.

CESM Project

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.

CESM is sponsored by the National Science Foundation (NSF) and the U.S. Department of Energy (DOE). Administration of the CESM is maintained by the Climate and Global Dynamics Division (CGD) at the National Center for Atmospheric Research (NCAR).
