Questions about CLM5's TWS component

[junho-kim]

Hello

I ran CLM5 for TWS simulation, and I got the results.

Additionally, I wanted to know the components of the TWS, so I looked up the TWS components in the CLM5 document (https://www2.cesm.ucar.edu/models/cesm2/land/CLM50_Tech_Note.pdf).

However, I found no information related to the components of the TWS (as such, TWS = soil moisture + Snow water + ...).

Therefore, my question is:

First, can I know the TWS component of CLM5?

Second, Is there any material or references related to the TWS component of CLM5?

Thanks

Total water storage is the sum of canopy water, snow water, surface water, plant stored water, water in the soil, and water in the rivers.
For details, you can grep in the code for TWS:

call hist_addfld1d (fname='TWS', units='mm', &
avgflag='A', long_name='total water storage', &
ptr_lnd=this%tws_grc)

and then trace where tws_grc is calculated in the code.
