The purpose of this research is to estimate evapotranspiration in urban areas using satellite remote sensing data and a surface heat balance model. In this research, we proposed an estimation method to determine surface parameters, and to simulate surface heat-balance in urban areas. As a result, characteristics of latent heat fluxes in built-up areas, green areas and residential areas were well represented by this method in conjunction with the conventional method using vegetation index data.
