 This paper presents a novel approach for estimating global evaporation using satellite data. It combines microwave-derived soil moisture, land-surface temperature, and vegetation density with rainfall interception loss to develop a simplified version of the Priestly-Taylor-PT evaporation model. The model was tested on one year of eddy covariance measurements from 43 sites around the world and showed strong correlations between the estimated evaporation and the measured values are equal 0.80. Additionally, the model performed well in different climates and vegetation types with an average correlation coefficient of are equal 0.83. Finally, the authors produced the first global map of annual evaporation based on their methodology. This article was authored by D. G. Morales, T. R. H. Holmes, R. A. M. Dejeu, and others.
