dc.description.abstractAbstract: The objective of this paper is to contribute to improve ETa estimation in semiarid environments by proposing two variations to the TDMT model. These variations are based on the use of MODIS products from TERRA or AQUA satellites and on the use of NDVI instead of EVI, to estimate the fraction of vegetation cover. The proposed changes were validated with the original methodology for the 2012-2014 period with data obtained from two flux towers (ES-LJu and ES-Amo). The best results were obtained when using the alternative methodology (RMSE of 0.64-0.67 mm in ES-Lju and of 0.97-1.02 mm in ES-Amo). Additionally, a correction of the temporal systematic errors of the model based on Random Forest is proposed. With this correction, RMSE of 0.31-0.35 mm in ES-Lju and 0.30-0.34 mm in ES-Amo were obtained. The spatial distribution obtained with this corrected model is the most consistent with the characteristics of the study areaes
