How to run an Irrigation Simulation in WRF-CTSM?

[Xiao.zh]

Hi all, I am wondering how to run an irrigation simulation in WRF-CTSM.
In Clm5, irrigation simulation could be done by:
# Note here we do a CLMSP simulation as that is what has been validated
> cd scripts
> ./create_newcase -case IRRIG -res f19_g17_gl4 -compset I1850Clm50BgcCrop
> cd IRRIG
# Append "-irrig on" to CLM_BLDNML_OPTS in env_run.xml (you could also use an editor)
> ./xmlchange CLM_BLDNML_OPTS="-irrig on" -append
> ./case.setup
# Now build and run normally
> ./case.build
> ./case.submit
In WRF, by setting parameters like sf_surf_irr_scheme.

How to change settings like irrigation, MOSART in WRF-CTSM.
I just compiled the WRF-CTSM and am not familiar with it. I will be grateful if anyone could help me out. Thanks a lot.

Do I need to change the variables in 'runtime_inputs/lnd_in' ？

I'm not certain, but I think you have the right idea:
Copy all the irrigation settings from the lnd_in of your Clm5 case to the lnd_in of your WRF-CTSM case. In a Clm case you would place these settings in the user_nl_clm file. I would do the same in the WRF-CTSM case, if you have a user_nl_clm file.
