N2 - The present paper outlines and tests a method for satellite mapping of evapotranspiration based on the canopy resistance theory. The dataset used for the analysis was obtained during a campaign conducted in an agricultural region east of Jutland, April to August /990. Scale between /ow-resolution NOAA satellite images and ground truth values were tested with a single high-resolution Landsat satellite The results are found to be in accordance with field In accordance with canopy resistance theory, a simple algorithm was found effective for evapotranspiration using satellite data. This approach also produced beuer differences between. fields than a model based on net radiation. air temperature. and satellite-derived surface temperature.
