Research direction

Start by reviewing issue #34, then inspect the cesm3_0_beta04 sandbox and the listed CESM case directory. Apply the specified hybrid-run, CAM, and MOM settings, and use the linked diagnostics and permanent output paths to verify that the 1 percent CO2 experiment completed and its results were saved.

Written by the indexing model from the issue text.

Description

Purpose:

1 percent co2 to assess TCR in 121 configuration

Description:

Same as #34 except:

Start from b.e30_beta04.BLTHIST.ne30_t232_wgx3.121 at yr 125

./xmlchange RUN_REFCASE=b.e30_beta04.BLT1850.ne30_t232_wgx3.121
./xmlchange RUN_REFDATE=0125-01-01
./xmlchange  RUN_TYPE=hybrid
./xmlchange  GET_REFCASE=true
./xmlchange  RUN_REFDIR=cesm2_init

4xco2 flbc in user_nl_cam

 flbc_cycle_yr          = -1
 flbc_file              = '/glade/campaign/cesm/cesmdata/cseg/inputdata/atm/waccm/lb/LBC_CMIP6_1pctCO2ramp_y1-165_0p5degLat_c180930.nc'

turn off CHECK_BAD_SURFACE_VALS in user_nl_mom
This prevents crashes.

CHECK_BAD_SURFACE_VALS = FALSE
