AB  - This dataset is the daily 25km snow density data of China's land area, covering the time range from 2013 to 2020, with a geographical range of 71.97 ° -136.74 ° E and 16.31 ° -54.31 ° N. It is a raster data in TIF format and contains a total of 2186 TIF files.The snow density dataset is based on the ground survey data and snow station observation data obtained from the "China Snow Characteristics and Distribution Survey" project of the National Science and Technology Basic Resources Survey from 2017 to 2019, as well as the observation data from the China Meteorological Station from 2013 to 2020. It combines satellite remote sensing snow product data, terrain elements, and meteorological elements provided by reanalysis data to produce a spatiotemporal simulation model of snow density that combines spatiotemporal weighting and machine learning. This dataset reflects the spatiotemporal distribution information of large-scale snow cover density in China's land area, and is suitable for research and application in snow cover characteristics, snow water resources, snow cover disasters, and other aspects.
