Mar 01, 2020· 1. Introduction. Evaporation acts as an exchange function for soil moisture and air water vapor at the land–atmosphere interface (Monteith 1965; Yan and Chen 1990; Ali et al. 2008), and consumes more than half the solar energy absorbed by the land (Kiehl and Trenberth 1997).It is a critical component when measuring the underlying surface water balance and …
