Abstract

In order to obtain improved estimates of spatial-temporal evapotranspiration (ET) and to study the related effects of land and near-surface atmosphere interactions, different soil vegetation atmosphere transfer models (SVAT) are coupled with a water balance model of vegetation root zone using data assimilation techniques to update soil moisture. Within this context we developed the Spatial EvpoTranspiration Modelling Interface (SETMI) in which three different thermal remote sensing-based models are included: the one layer model (OLEM), the two source model (TSM), and the Surface Energy Balance (SEBAL) to provide estimates of surface energy fluxes and daily ET. The water balance model of the root zone is the one proposed in the FAO Paper 56 which was included to provide daily and seasonal estimates of ET and was modified to use the reflectance-based basal crop coefficient (Kcbrf) obtained from remote sensing. SETMI can also be combined with simple soil water dynamics models to provide multilayer root zone soil moisture estimates.
