Evapotranspiration is an important parameter to optimize water use, especially in non‐irrigated and arid or semiarid rangelands. A simplified method to derive the daily evapotranspiration using remote sensing images of high and low spatial resolution is presented in this paper. The method is based on the evaporative concept employed in the S‐SEBI (Simplified Surface Energy Balance Index) model, and it is applicable under the assumption of constant atmospheric conditions and sufficient wet and dry pixels over the image. The method, applied to DAIS and NOAA‐AVHRR images, has been tested using ET values measured over the agricultural area of Barrax (Castilla‐La Mancha, Spain), and an accuracy for the daily evapotranspiration lower than 1 mmd−1 has been obtained..
