青藏高原 GLASS 地表反照率产品精度分析
An assessment on the accuracy of the GLASS albedo products over the Tibetan Plateau
摘要
Abstract
The accuracies of the GLASS (Global LAnd Surface Satellites)albedo products in 1 km resolution are assessed using the ground measurements of year 2003 at three stations over the Tibetan Plateau.The results show that the overall change trends of the GLASS black-sky and white-sky albedos are consistent with the ground-observed albedos,which could indicate the state of surface fair well;both the small fraction of snow cover and cloud cover have great effect on the accuracy of the GLASS albedo products and cloud cover might result in higher values of GLASS albedo products than ground measurements;the RM-SEs (root-mean-square errors)between the GLASS black-sky albedos,GLASS white-sky albedos and ground measurements are evidently decreased when eliminating the effect of snow and cloud cover,which are 0.0155 and 0.019,respectively.关键词
