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...

Abstract Accurate spatio-temporal estimation of evapotranspiration (ET) and surface energy fluxes is crucial for many agro-environmental applications, including the determination water balance, irrigation scheduling, agro-ecological zoning, simulation global changes in land use forecasting crop yields. Remote sensing based balance models are presently most suitable estimating ET at both tempora...
