[Wrf-users] WRF Evapotranspiration, SFCEVP vs LH vs ECAN+EDIR+ETRAN

[Stephanie A. Spera]

Hi all,


I'm interested in differences in total evapotranspiration across my simulations, and I'm a little lost as to which variables I should be looking at, especially as I tried to compare across ET related variables.


There is latent heat (LH); evaporation of intercepted water, ground surface evaporation and transpiration rate (ECAN + EDIR + ETRAN); and accumulated surface evaporation (SFCEVP), all of which I can convert to mm/day. However, when I do the (hopefully) correct math, and compare across variables, each provides a different ET amount. Any ideas as to why this would be, or which set of variables I should rely on?


Thanks,

Stephanie
