This paper presents results of surface temperatures for a part of the Godavari and Tapi Basins, India. Thermal infrared remote sensing proved its capability in monitoring temperature field. Landsat data of the study area have been used for the surface temperature estimation and analysis. The method used to extract surface radiance from the digital number (DN) values is based on USGS, 2001. Landsat 7 Science Data User’s Handbook. The surface temperature is then extracted from the surface radiance. Based on Landsat image, average temperature of the study area is 25 C, minimum temperature as 15oC, maximum temperature as 35oC respectively, are inferred. The results have been compared with data obtained by India Meteorological Department data. The comparison of observed temperatures has shown a good correlation, with a difference of 2-2.5 C.
