| Abstract: | It is a new method to estimate land surface evapotranspiration of large region by using remote sensing. This paper analyzes several remote sensing models of land surface evapotranspiration such as Land Surface Energy Balance, Complementary Relationship of Land Surface Evapotranspiration, Penman Montieth and Climatology Method of Regional Evapotranspiration. Methods to derive land surface parameters from remote sensing data are given. The paper meteres include Albedo, NDVI, Surface temperature and Emissivity, which are used widely at home and abroad. The relationship among them are delineated. |
