Hasager, Charlotte Bay: Satellite remote sensing as a tool for spatial evapotranspiration estimation in vegetated areas. Geografisk Tidsskrift 93:56–62. Copenhagen 1993. 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 field campaign conducted in an agricultural region east of Viborg, Jutland, April to August 1990. Scale between low-resolution NOAA satellite images and ground truth values were tested with a single high-resolution Landsat satellite image. The results are found to be in accordance with field observations. In accordance with canopy resistance theory, a simple empirical algorithm was found effective for evapotranspiration estimation using satellite data. This approach also produced better defined differences between fields than a model based on net radiation, air temperature, and satellite-derived surface temperature
