Catchment scale estimation of evapotranspiration from remote sensing data based on an energy balance approach: A validation study for the Rur catchment, Germany

Owing to its dependency on the amount and duration of incoming solar radiation and other meteorological parameters, changes in evapotranspiration (ET) may occur on short time scales (less than an hour). Therefore, monitoring the temporal and spatial anomalies in ET are very important. This study aims to estimate evapotranspiration on a regional scale, using an energy balance approach based on remote sensing data
