AbstractInfrared temperatures at varied spatial resolution could be obtatined efficiently and accurately, and therefore, it is important to address its usefulness in estimation of regional evapotranspiration. A comparison of ground measured and satellites determined surface temperatures has been performed in the 1987 summer. The ground measurements were located over nearly homogeneous water and arable crops surfaces to determine the variation of surface temperature. A method has recently been developed to deduce the latent heat flux over active surface from remote sensed temperature. We calculated the evapotranspiration using the energy balance equation substituting the infrared temperatures.
