Problems regarding WRF-Hydro output variable

[Lise-Li]

Hi, WRF-Hdyro Team:
I am trying to figure out the relationships among the various variables related to runoff in the WRF-Hydro output. As shown in wrf-hydro user guide, the SFCRNOFF and UGDRNOFF represent Accumulated surface runoff and Accumulated underground runoff, represtively. The sum of SFCRNOFF and UGDRNOFF is the total runoff. I want to know how can I seperate the total runoff into rainfall-runoff, snowmelt and baseflow through variables in LDASOUT_DOMAIN file? Is the variable ACSNOM can represent the snowmelt?
In addition, I want to know how can I seperate the components (e.g., rainfall, snowmelt etc.) in streamflow output?
Thanks for your attention! I'm looking forward to your reply!
Best regards,
