Through resampling, splicing and other processing, the annual average snow cover rate data of Qaidam Basin from 2000 to 2018 is obtained. Through regression analysis of each pixel, the 1km resolution snow change rate data of Qaidam region from 2000 to 2018 is obtained. Through the establishment of 100 km fishing nets in ArcGIS, the snow change rate in each fishing net is processed to obtain the 100 km resolution snow change rate. This data set is mainly applied to the scientific research of Cryosphere.
