Retrieved with the combined data from multiple satellites, the GlobAlbedo provides the global land surface albedo (LSA) product, and it is delivered by the European Space Agency (ESA). To evaluate the accuracy of the GlobAlbedo and advance its application in the study of the earth-atmosphere interaction over the Qinghai-Xizang Plateau, the ground-observed solar shortwave radiation data from BJ and XDT stations, located over the Northern Qinghai-Xizang Plateau, were used to make comparison with the GlobAlbedo. Besides, the comparison was also made between the GlobAlbedo and the Moderate Resolution Imaging Spectroradiometer LSA product MCD43B3. Results revealed that: The shortwave band (0.3~5.0 μm) land surface albedos from the GlobAlbedo in 1 km resolution were totally in rather well agreement with the ground-observed land surface albedo, but their accuracy were significantly influenced by the snow fraction (SF). The root-mean-square errors (RMSEs) between the actual land surface albedos from GlobAlbedo and the high-quality ground-observed land surface albedos fell in between 0.0100 and 0.0218 when the SF was less than 0.1, and the accuracy of GlobAlbedo could meet the requirements of the land surface process and climate models. Otherwise, they fell in between 0.0252 and 0.1461 and there were some uncertainty in the accuracy of GlobAlbedo. When compared with MCD43B3, the GlobAlbedo has a slightly better accuracy than MCD43B3. The RMSEs between the actual land surface albedos from GlobAlbedo and the high-quality ground-observed land surface albedos fell in between 0.0195 and 0.0959, while those between the actual land surface albedos from MCD43B3 and the high-quality ground-observed albedos fell in between 0.0273 and 0.1269.
