Evaporation estimation for Lake Nasser based on remote sensing technology

Evaporation rate obtained from this method is instantaneous since it is estimated during the satellite overpass over the lake. However, evaporative fraction method is used to estimate the daily rate from the instantaneous one. The surface energy balance combined with remote sensing data proves promising to estimate evaporation rates for large water bodies. These could lead to more accurate monitoring of evaporation rates in the lake area without being dependent on field observations, which are sometimes unavailable or uncertain for these types of studies.
