CLM5.0 history field problem with "WF"

[frriquelme]

Hello,

I am working with an F compset (1850_CAM60_CLM50%SP_CICE%PRES_DOCN%DOM_RTM_SGLC_SWAV) to make a sensitivity test. I am keeping some CAM variables and I want to register only one CLM5.0 varible: WF (soil water as frac. of whc for top 0.05 m). However, the model gives me an error in the beginning of the run:

htapes_fieldlist ERROR: WF in fincl( 2 ) for history tape
1 not found
).

WF appears in CTSM History Fields but I realize that in the last column it specified that this variable is no Active.

So, here some questions:
- It is possible to active this variable?
- My problem is related to my compset? (I am using RTM instead of MOSART)
- If it is not possible to use WF is other way to calculate the water fraction over the superficial layer of soil?

Hope you can help me.

Best,
Fabian.

In components/clm/src/biogeophys/WaterStateType.F90 I see:

if (use_cn) then
this%wf_col(begc:endc) = spval
call hist_addfld1d (fname='WF', units='proportion', &
avgflag='A', long_name='soil water as frac. of whc for top 0.05 m', &
ptr_col=this%wf_col, default='inactive')
end if

So that variable is only available if "use_cn" is true. You would need CLM50%BGC or CLM50%BGC-Crop instead of CLM50%SP.
You could try commenting out the if statement but the wf_col variable may not be calculated/available in SP mode.

Thanks for your answer!

I will try to do something to get what I nedd.

Thanks again,
Fabian.
