Configuration setting for compsets

Change CAM_CONFIG_OPTS

You may have to run ./xmlchange --append CAM_CONFIG_OPTS=### in a few scenarios.

• To select a 32 or 58 level you should use the appropriate -nlev=###. 32 is the default for many compsets. You will need to set this for 58 levels
• FHS94, FKESSLER, and QPC6 use analytic initial conditions with the MPAS-A dycore. You may have to add this option yourself.

E.g. to request 58 levels and ensure analytic initial conditions are used run the following after running ./case.setup: ./xmlchange --append CAM_CONFIG_OPTS= -nlev=32 -analytic_ic

Additional Configuration Changes

Use the following commands to set the configurations for your runs (These commands includes the configuration change to CAM_CONFIG_OPTS). These changes are specific to Cheyenne and the paths need to be updated accordingly for other machines. The CIME infrastructure downloads the necessary files at runtime at lower resolutions. But the user needs to manually specify the path in the user namelist at a higher resolution (see EarthWorks Inputdata).

FHS94

No additional commands are needed for FHS94

FKESSLER

See Known Issues for a note about FKESSLER. Otherwise no extra commands are needed for FKESSLER
