Estimation of daily evapotranspiration using a two‐layer remote sensing model

A two‐layer remote sensing model for estimating daily evapotranspiration over a large area was developed. The model followed an energy balance approach, where evapotranspiration is estimated as a residual when net radiation, sensible heat flux and ground flux are known. The accuracy of the model outputs was determined using harmonized surface conditions derived from measurements from ground stations. An accurate agreement (r 2 = 0.844, n = 48) between estimates and ground‐based measurement was obtained.
