Short summary
We present an empirical method to retrieve actual evapotranspiration (ET) at a spatial resolution of 250m for the eastern Mediterranean based on observed relationships between satellite vegetation indices and eddy covariance ET. Our model was successfully evaluated against two physically based models and calculated ET from water catchment balances along rainfall gradient. In the absence of high-resolution models, our model is expected to contribute to the ecohydrological study of this region.
