The study on evapotranspiration´s parameter retrieval from RS data and it´s validation-with Zhelin basin as a example

It is common to retrieve some evapotranspiration parameters from the remote sensing data, with the development of information technology. Under this background, this study selects Zhelin basin located in north of China as a typical area. In the study area, the paper retrieved the Evapotranspiration and the potential evapotranspiration on the basis of remote sensing data with the energy-balance method which was programmed into the CEWBMS model by the Netherland colleagues. After that, the paper analyzed the distribution of those retrieval data and validated the accuracy.
