Based on Snow Cover Survey Data of Accuracy Verification and Analysis of Passive Microwave Snow Cover Remote Sensing Products in Northeast China
Snow cover products can provide temporal and spatial information on snow cover distribution,which is an important data source for snow monitoring. The accuracy validation and contrastive analysis of the remote sensing products are helpful to the further development and application of snow cover data products. the survey project of snow cover characteristics and distribution in China are taken for validating the applicability of snow cover products in Northeast China,The inversion accuracy of FY-3B snow depth product, AMSR-2 snow depth product and GlobSnow snow equivalent product under two underlying surface of Broadleaf Forests and Croplands were verified by using the 25 km typical quadrats and snow path survey data in Northeast China. The results show that the precision of GlobSnow snow water equivalent product has the highest accuracy and the maximum deviation and root mean square error without distinguishing the underlying surface are respectively 10.87 cm and 12.53 cm.The inversion accuracy between GlobSnow snow equivalent product and FY-3B snow depth product under two underlying surfaces is very little and the difference of deviation and root mean square error between two products is respectively smaller than that of 2.11 cm and 3.46 cm.The inversion accuracy of AMSR-2 products under two kinds of underlying surfaces is significant different and the difference of deviation and root mean square error between the two underlying surfaces is greater than that of 9.94 cm and 7.19 cm. For the three snow products, The inversion accuracy of snow depth on the underlying surface of croplands is higher than that of broadleaf forests on the underlying surface.
