Amtis and aster images were scaled up using pixel aggregation algorithm to find scaling error of surface flux estimation. the results show that the largest error appears at the interface of different coverage types, and the error show much complexity because of the discontinuity of algorithms at these boundaries. additionally, the contamination of building, highway and other ground information also add some error in the estimation of land surface e vapotranspiration
將amtis和aster圖像降低解析度后計算通量，檢驗其尺度誤差，結果表明，在不同覆蓋類型的交界處通量誤差比較明顯，由於演算法本身的不連續性，其誤差規律較為復雜，另外，道路、建築等對通量計算無用的信息也是造成大像元尺度誤差的原因之一。
