Paper Abstract

Mixed pixels constitute AVHRR image. Evapotranspiration (ET) calculated from AVHRR image certainly includes some mistake information of ground objects which have no meaning as far as ET is concerned. Registration of AVHRR image and high spatial resolution image is carried out. A meteorology-RS combination model is used to calculate the ET of the AVHRR image and of the cropping area of the corresponding high resolution image respectively and the difference of these two ETs is given. The error is analyzed and a corresponding statistical calibration method adaptable to test region is given.
