MOM6-examples using CESM

[paulhall]

Is it possible to run the test cases from MOM6-examples under CESM, or are there some funadmental differences in the way scenarios are set up under CESM that prevents this?

I have been trying to run some of the ocean-only test cases (e.g., double-gyre, CVmix_SCM_tests) under CESM 2.2 w/MOM6 by turning off everything but the ocean (i.e., ./create_newcase --run-unsupported --res T62_t061 --compset 2000_DATM%NYF_SLND_SICE_MOM6_SROF_SGLC_SWAV) and using diag_table, MOM_input, and MOM_override from the examples, but I haven't been able to make it work. Is there an inherent incompatibility (possibly due to conflicts in how the grids are defined in CESM vs in the examples)? Any advice/pointers would be appreciated.

Thanks!
Paul

Technically, it is possible to run the ocean-only cases in MOM6-examples using CESM. However, this would require creating and configuring new compsets, which is a lot of work. If you plan on running idealized test cases (e.g., double-gyre, CVmix_SCM_tests), I strongly recommend that you follow this approach instead.

Thanks Gustavo. I have run the test cases using MOM6 as a stand alone application. I was hoping to use the test cases as a starting point to create a coupled ocean-atmosphere "pencil" model in CESM. I take it from your response that the way forward for this is ultimately to create a new compset? Do you have any recommendations for documentation or tutorials on creating compsets in CESM?

Yes, you want to create a new compset for that. This notebook that Alper Altuntas created a few years ago might help you. It provides instructions on how to create a compset for global MOM6 applications using the MCT coupler and infrastructure.

Thanks! I will take a look at the notebook.
