STIMA DELL’EVAPOTRASPIRAZIONE EFFETTIVA MEDIANTE TELERILEVAMENTO AEREO IPERSPETTRALE

Abstract

The general aim of this paper is to demonstrate that remote sensing techniques may easily provide the information needed for the application, over large areas, of agro-hydrological models for the actual evapotranspiration estimation. The application of the SEBAL model has been investigated at field scale and at district scale using highresolution hyperspectral (VIS/NIR + TIR) airborne data acquired in a Sicilian test area. In a first phase, SEBAL has been validated by means of scintillometer flux measurements. Then an application over a district area using MIVIS airborne data has been performed. The procedure provides the actual daily evapotranspiration distribution for a set of irrigated arboreous crops, confirming the potential advantage of this approach as an operative future tool useful to improve the efficiency of irrigation systems.
