The validation of MODIS daily snow-cover products after cloud removal in Tibet Autonomous Region

In this paper, the method of cloud removal applied to MODIS/TERRA and AQUA snow products was validated in Tibet Autonomous Region, the leakage measurement error L (%), more measurement error M (%), overall accuracy O (%) and kappa coefficient (Khat) was chosen as evaluation index; cloud removal of c...

description In this paper, the method of cloud removal applied to MODIS/TERRA and AQUA snow products was validated in Tibet Autonomous Region, the leakage measurement error L (%), more measurement error M (%), overall accuracy O (%) and kappa coefficient (Khat) was chosen as evaluation index; cloud removal of combination of TERRA and AQUA products (I), cloud removal of combination of snow products for three days (II) and Snowl cloud removal based on DEM (III) were the three methods of cloud removal work. In addition, five typical regions of Tibet were chosen to be researching places, so as to make the study more convincing. The results show that Methods (I) and (II) are suitable to use in this research areas for cloud removal, and there are many uncertainties in Method (III). After cloud removal by the three methods, for the five regions, it is found that the overall accuracy O rising to 60%-98%, the snow classification precision S rising to 60%-95%, and the Kappa coefficient ranging from 0.10 to 0.56 in general.
