CLM 4.1 Running with the prognostic crop model on - erika72/clm-docs GitHub Wiki
The prognostic crop model is setup to work with CLM4.5-BGC or CLM4.0-CN (with or without DV) for present day conditions and we have surface and initial condition datasets at f19 resolution. In order to use the initial condition file, we need to set the RUN_TYPE to startup rather than hybrid since the compset for f19 sets up to use an initial condition file without crop active. To activate the crop model you can choose a compset that has "CROP" in the name such as "ICRUCLM45BGCCROP" or simply add "-crop on" to CLM_CONFIG_OPTS.
> cd scripts
> ./create_newcase -case CROP -res f19_g16 -compset I1850CRUCLM45BGC -mach yellowstone_intel
> cd CROP
# Append "-crop on" to CLM_CONFIG_OPTS in env_build.xml (you could also use an editor)
> ./xmlchange CLM_CONFIG_OPTS="-crop on" -append
# Change to startup type so uses spunup initial conditions file for crop if it exists
# By default the model will do a hybrid startup with an initial condition file
# incompatible with the crop surface dataset.
> ./xmlchange RUN_TYPE=startup
> ./cesm_setup
# Now build and run normally
