Different methods have been developed to estimate evapotranspiration from remote sensing data. Among them direct methods based upon the energy balance equation and using thermal infrared (TIR) data like the simplified relationship. This method has been applied for various situations: from small spatial scale using airborne TIR images to continental scale with NOAA data. More recently indirect e...

This paper compares evapotranspiration estimates from two complementary satellite sensors - NASA's Moderate Resolution Imaging Spectroradiometer (MODIS) and ESA's ENVISAT Advanced Along-Track Scanning Radiometer (AATSR) over the savannah area of the Volta basin in West Africa. This was achieved through solving for evapotranspiration on the basis of the regional energy balance equation, which wa...

A study on evapotranspiration for wheat was conducted in the two-year Rabi season crop from November, 2017 to April, 2018 and April 2019 at Gaya District, Bihar. Spatio-temporal information actual (ETa) helps users better understand evaporative depletion establish links between land use, water allocation, use. The Surface Energy Balance Algorithm Land (SEBAL) adopted employing essential adaptat...
