As of , this is done by modifying namelist_scream.xml either by hand or by using the atm-config-chg atmchange function which now comes bundled when you create a case. Explore namelist_scream.xml for variables you might want to change (but you shouldn’t have to change anything to run).

  • if you want to run with non-hydrostatic dycore:

    • Change to tstep_type=9 (or run ./atm-config-chg atmchange tstep_type=9 in case directory)

    • Change to theta_hydrostatic_mode=False (or run ./atm-config-chg atmchange theta_hydrostatic_mode=False)

  • To modify what output gets written, change ./data/scream_output.yaml file under the run/data/ directory

  • Some bugs are affected by chunk length for vectorization, which is handled by “pack” size in v1. Pack size can be tweaked by editing the cmake machine file for the current machine (components/scream/cmake/machine-files/$machine.cmake).
