The China Historical Snow Cover Dataset (2008-2016) is compiled from historical field survey data of snow cover contributed by snow cover research teams from multiple institutions, including the Northwest Institute of Eco-Environment and Resources of the Chinese Academy of Sciences, the National Satellite Meteorological Center of the China Meteorological Administration, meteorological bureaus of Xinjiang Uygur Autonomous Region, Qinghai Province, Heilongjiang Province, and Inner Mongolia Autonomous Region, the Northeast Institute of Geography and Agroecology of the Chinese Academy of Sciences, Nanjing University, Beijing Normal University, and other relevant units. This dataset was collected primarily via manual observations supplemented by automatic observations, driven by project requirements, operational and scientific research needs, and personal interests. Following this consolidation effort, the dataset has been standardized uniformly, and missing digitized data has been supplemented.
It is specifically divided into 14 sub-datasets: 1. Dataset of Snow Spectral Reflectance with Different Particle Sizes in Northern Xinjiang (2010); 2. Observation Dataset of Snow Cover Properties in Heilongjiang Province (2016); 3. Observation Dataset of Snow Cover Freeze-thaw Cycle Process at Huailai Remote Sensing Comprehensive Test Station (2012); 4. Snow Cover Microwave Radiation Observation Dataset in Songyuan City, Jilin Province (2010); 5. Snow Cover Observation Dataset in Xilinhot Grassland, Inner Mongolia Autonomous Region (2018-2020); 6. Automatic Observation Dataset of Snow Cover Parameters and Soil Parameters on the Qinghai-Tibet Plateau (2015-2016); 7. Snow Cover Properties and Albedo Dataset in Qilian, Qinghai Province (2008); 8. Daily Snow Cover Characteristics Dataset at National Standard Climatic Station of Altay, Xinjiang Uygur Autonomous Region (2015-2016); 9. Snow Cover Characteristics Survey Dataset in Altay, Xinjiang (2016); 10. Snow Depth and BRDF Observation Dataset in Altay, Xinjiang (2015); 11. Snow Cover Characteristics Survey Dataset in Manas River Basin, Xinjiang (2013-2014); 12. Dense Automatic Observation Dataset of Surface Snow Cover in Typical Snow Cover Areas of China (2013-2019); 13. Snow Cover Route Observation Dataset in Xiaoxing'an Mountains and Changbai Mountains Area of China (2012-2013); 14. Station Observation Dataset of Snow Cover Parameters in Manas River Basin, Xinjiang, China (2012-2017).
This dataset includes parameters such as snow depth, moisture, density, particle size, layering, classification, specific snow surface area, spectral reflectance, BRDF, albedo, microwave radiation brightness temperature, layered density, temperature, moisture, particle size, dielectric constant of snow profiles, snow cover environment photos, air temperature, soil temperature, soil volumetric water content, soil electrical conductivity, and soil complex dielectric constant. Spatially, it covers the three typical snow cover regions in China: Northeast China-Inner Mongolia, Xinjiang, and the Qinghai-Tibet Plateau, with a temporal coverage of 2008-2020. The observation elements cover the full range of snow-related and environmental parameters detailed above. The dataset contains 36 folders and 857 files in multiple formats including xls, txt, doc, jpg, png, etc., with a total size of 327 MB.
