Résumé
Evapotranspiration (ET), which is a fundamental variable of the hydrological cycle, is still not know with precision over forested area in Mediterranean areas. Remote sensing data, that inform on vegetation coverage and meteorological reanalysis can be used to improve our knowledge on the distribution of ET in space and time.A simple model using remote sensed fraction cover, meteorological data and soil AWC from various source is presented. When considering spatially available information, uncertainties in model inputs (fcover, ETo, precipitation and soil information) strongly impact the simulation of evapotranspiration
