As for use_case, I used aquaplanet_cam4.xml. CESM version 2.0.1 (the original public-release version of CESM2, and scientifically identical to public version 2.1.0) was run on a nominal 1-degree finite-volume horizontal grid for 30 years to assess the model's ability to represent atmospheric rivers (extreme precipitation events) and their related weather patterns. Modifying namelist settings ¶ Once the code is running, you may want to change namelist or configuration variables. However, to change the CPP variables, one needs to add these to the CICE_CONFIG_OPTS variable in the env_build.xml file. I was planning to run time slices 2045-2055.
