摘要：
Because of similar reflective characteristics of snow and cloud,the weather status seriously affects snow monitoring using optical remote sensing data.Cloud amount analysis during 2010 to 2011 snow seasons shows that cloud cover is the major limitation for snow cover monitoring using MOD10A1 and MYD10A1.By use of MODIS daily snow cover products and AMSR-E snow water equivalent products(SWE),several cloud elimination methods were integrated to produce a new daily cloud free snow cover product,and information of snow depth from 85 climate stations in Tibetan Plateau area(TP)were used to validate the accuracy of the new composite snow cover product.The results indicate that snow classification accuracy of the new daily snow cover product reaches 91.7% when snow depth is over 3 cm.This suggests that the new daily snow cover mapping algorithm is suitable for monitoring snow cover dynamic changes in TP.
