Add diag_mode to default diagnostics #462

Closed mnlevy1981 closed 6 months ago

mnlevy1981 commented 6 months ago

Introduce new diag_mode option to MARBL_generate_diagnostics_file.py; when diag_mode = 'none', output diagnostic file should be 'never_{op}' for all variables. When diag_mode = 'minimal', only variables with diag_mode = 'minimal' in diagnostics_latest.json have non-never output frequencies. When diag_mode is 'full', variables with diag_mode = 'minimal' or 'full' will have non-never output frequencies.

Just to have this recorded somewhere, I tested this PR in CESM with ocean-only (MOM6) cases. Each was run for a single month.

MARBL_DIAG_MODE Size of RUNDIR
none 18 GB
minimal 19 GB
full 29 GB
test_suite 45 GB

Notes

  1. test_suite is only defined in MOM_interface; it writes monthly means of every diagnostic MARBL provides. For all the other values, MARBL_DIAG_MODE is used for diag_mode as defined in this PR
  2. MOM6 writes all output in single precision, with one exception: when diag_mode = test_suite, the MARBL diagnostics (as well as the MARBL tracer-specific diagnostics computed in MOM6) are written in double precision
