Dear help,

What is the quantity of SFCEVP when I choose sf_surface_physics = 2 which is NOAH LSM?

Is it total transpiration (tree + grass + soil ... )? or potential evaptranspiration?

SFCEVP is total moisture flux at the surface, equivalent to evapotranspiration.

QFX is calculated in phys/module_sf_noahdrv.F, which is then used to calculate SFCEVP

in phys/module_surface_driver.F


in phys/module_sf_noahdrv.F, you can track how QFX is calculated.

It is hard to describe the details and codes here. please read the code and relevant paper to better understand this issue.
