摘要：
Evapotranspiration is one of the important component in hydrological cycle and plays a major role in water balance studies of tropical and subtropical areas. Estimation of actual evapotranspiration using remote sensing is a step towards the real time spatial mapping of evapotranspiration. However, this estimation being a tedious process requires determination of heat and radiation fluxes with the help of field observations. Real time spatio-temporal mapping of ET will go a long way in solving problems of water use, land use and water allocation. In this paper we used Surface Energy Balance Algorithm for Land (SEBAL) estimating the actual evapotranspiration (ET) for upper Tapi basin (India). Study emphasises on the methodology of the model and energy flux components it operates on.
