CESM Models

CESM Models: CLM4.0 Offline Model Forcing Data


CLM Post Processing Utilities

The CLM diagnostics package can be accessed from the release code repository . The CLM post-processing utilities are currently provided only as a service to the community. Informal community support is provided via the CCSM bulletin board. General questions should be submitted to this bulletin board; however, any bugs found in the packages should be reported to the appropriate working group liaison.

Once approval is granted for access to the release repository, users may freely download the diagnostic packages. Users are urged to 'export' the packages from the repository rather than checking them out. For example:

  • svn export https://svn-ccsm-release.cgd.ucar.edu/model_diagnostics/lnd/clm/lnd_diag4.1.20/

will result in the user obtaining the post processing utilities "lnd_diag" verion 4.1.20. For more details on utilizing the release repository, please see the section on Downloading CCSM in the User's Guide


Other Post-Processing Utilities

  • NCL (NCAR Command Language)
  • NCO (NetCDF Operators)
