Remote Sensing Retrieval of Daily Evapotranspirationover the Heihe River Basin
黑河流域日蒸散发遥感估算研究

The estimation of evapotranspiration(ET) over heterogeneous land surface of arid and semi-arid regions is quite complicated and significant. NOAA/AVHRR remote sensing,NCEP reanalysis grid and meteorological station data are used to estimate daily ET over the Heihe River basin based on the integrating surface energy algorithm for land model and the Penman method. As for clear days,Remote sensing model is used to retrieval the instantaneous ET to daily ET. FAO-17 Penman method is also used to estimate the sam...
