TY - Data T1 - Daily snow density data set in China (2013-2020) A1 - None DO - 10.12072/ncdc.isnow.db2711.2023 PY - 2023 DA - 2023-01-25 PB - National Cryosphere Desert Data Center AB - This data set is the daily 25km snow density data of China's land area, covering the period from 2013 to 2020, and the geographical range is 71.97 ° - 136.74 ° E, 16.31 ° - 54.31 ° N. It is the grid data in TIF format, including 2186 TIF files. The snow density data set is based on the ground survey data and snow cover station observation data from 2017-2019 obtained by the national science and technology basic resources survey project "China Snow Cover Characteristics and Distribution Survey", as well as the observation data from China Meteorological Station from 2013-2020, combined with the meteorological elements provided by satellite remote sensing snow cover product data, terrain elements and reanalysis data, It is produced by using the spatiotemporal simulation model of snow density combined with spatiotemporal weighting and machine learning. This data set reflects the spatiotemporal distribution information of large-scale snow cover density in China's land area, and is applicable to the research and application of snow cover characteristics, snow water resources, snow cover disasters, etc. DB - NCDC UR - http://www.ncdc.ac.cn/portal/metadata/121b0f6b-0c76-4869-bd6f-f96ea452ba0e ER -
