Abstract
Application of a remote sensing technique for estimating regional evapotranspiration requires extrapolation of instantaneous values to periods on the order of 1 day or more to be of practical use. A method for developing an extrapolation coefficient based on earth-sun geometry is presented. The validity of the method and applicability of the concept is evaluated using year-long regional values of measured Penman evapotranspiration. The results demonstrate that the use of an extrapolation coefficient for long-term regional evapotranspiration estimation has a potential for future use.
