Level of support

Tier 1 NSC has at least one application expert on staff with knowledge about this software, and we will try to help you with any problems. We have also ran some internal tests to make sure that the program is working as intended. NSC also commits to installing updates to this program as they become available.

Please see the page describing our software support categories for more information.
You can also contact support@nsc.liu.se for further information.

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 Earths 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).

CESM at NSC is generally supported by Hamish Struthers (struthers@nsc.liu.se). See the CESM webpages for detailed documentation, examples, wiki, user forums, issue tracking and bug reporting. See also SNIC CESM documentation page.

How to build and run

In general, there are no system installs of CESM at NSC. Instead, the model can be built from the unmodified source code once registration is completed. Instructions for downloading the source code, building and running the model can be found on SNIC knowledge base: Building CESM on the NSC triolith system

If you are going to run one of the CESM models on triolith, you should join the ‘cesm1’ unix group on triolith. This is not absolutely necessary but being a member allows access to shared storage space on /nobackup/global/proj/cesm1 where pre-downloaded initial data and ancillary files are stored. Email support@nsc.liu.se to request membership to the cesm1 unix group. Please note: Files that you copy to the shared /nobackup/global/proj/cesm1 will be charged to your space allocation on triolith.

Running CESM batch jobs

Please see the User Guide for more information on how to submit and check the result of your batch jobs.
