Estimation of evapotranspiration and its partition based on an extended three-temperature model and MODIS products.

Highlights: [•] We successfully estimated ET and separated it into evaporation and transpiration. [•] The modeled absolute error was 0.08mm/d, and with a relative error of 10.67%. [•] Forest has the highest ET, followed by grassland, farmland, and desert. [•] ET rendered a decrease from the upper reaches to Gobi desert of the lower reaches. [•] About 38–72% soil water returned to the atmosphere in the form of evaporation. [ABSTRACT FROM AUTHOR]
