Paper Abstract

The use of remote sensing technology to estimate regional evapotranspiration has been carried out for many years. Recently, with the advancements in quantification of remote sensing and the access of MODIS data, more scientists have been using MODIS data to monitoring regional evapotranspiration (ET) instead of the NOAA/AVHRR data. The surface energy balance algorithm for land (SEBAL) model combined with NOAA/AVHRR and MODIS data separately is applied to estimate the 24-hour regional evapotranspiration in a semi-arid agricultural area of northern China. And the SEBAL regional evapotranspiration model calculated results from MODIS and NOAA/AVHRR data are compared with the in-situ measured ground surface evaporation. The analysis shows that in estimating regional evapotranspiration of the satellite based application, MODIS data is more appropriate than NOAA/AVHRR data.
