Resum

The aim of this study is to monitor daily actual evapotranspiration (AETd) in Pinus sylvestris forest stands using a simplified methodology. To compute AETd we have followed the B-method, which is based on the energy budget, using a series of TERRA/AQUA MODIS and Landsat-5 TM as Remote Sensing data from 2003 to 2004. We have compared Remote Sensing AETd estimates with sap flux measurements obtaining a RMSE of 0.78 mm in the case of Landsat data, 0.93 mm in the case of TERRA MODIS and 0.91 mm in the case of TERRA AQUA using a variable B parameter in AETd modeling.
