Estimation of Mediterranean crops evapotranspiration by means of remote-sensing based models
2009
Abstract. Actual evapotranspiration from typical Mediterranean crops has been assessed in a Sicilian study area by using Surface Energy Balance and Agro-Hydrological models. Both modelling approaches require remotely sensed data to estimate evapotranspiration fluxes in a spatially distributed way. The first approach exploits visible (VIS), near-infrared (NIR) and thermal (TIR) observations to solve the surface energy balance equation. To this end two different schemes have been tested: the two-sources TSEB model, where soil and vegetation components of the surface energy balance are treated separately, and the widely used one-source SEBAL model, where soil and vegetation are considered as a…
Estimation of actual evapotranspiration of Mediterranean perennial crops by means of remote-sensing based surface energy balance models
2009
Abstract. Actual evapotranspiration from typical Mediterranean crops has been assessed in a Sicilian study area by using surface energy balance (SEB) and soil-water balance models. Both modelling approaches use remotely sensed data to estimate evapotranspiration fluxes in a spatially distributed way. The first approach exploits visible (VIS), near-infrared (NIR) and thermal (TIR) observations to solve the surface energy balance equation whereas the soil-water balance model uses only VIS-NIR data to detect the spatial variability of crop parameters. Considering that the study area is characterized by typical spatially sparse Mediterranean vegetation, i.e. olive, citrus and vineyards, alterna…
Estimación de flujos de energía utilizando un modelo micrometeorológico e imágenes de satélite
2008
El creciente interés de las comunidades científicas meteorológicas, climáticas e hidrológicas por los distintos componentes del balance energético de superficie, y especialmente por la evapotranspiración, ha fomentado el desarrollo de distintos modelos micrometeorológicos para evaluar los flujos de energía de superficie a escala local. Los recientes avances en las técnicas de teledetección satelitaria podrían permitir el seguimiento de estos flujos de energía de superficie sobre zonas extensas. Sin embargo, la mayoría de los modelos actuales requieren calibraje in situ o parámetros derivados empíricamente, cosa que limita su aplicación operacional a gran escala. El objetivo de este trabajo …
