Special data set of snow disaster in pastoral areas of Qinghai Tibet Plateau

This data set uses the daily snow observation data of 109 ground meteorological stations in the Qinghai Tibet Plateau, and according to the classification criteria of snow disasters in the Meteorological Disaster Classification Index (DB63/T372-2018), counts the days of mild, moderate, severe and extra severe snow disasters in the Qinghai Tibet Plateau in the past 20 years. The snow disaster data set formed can provide data support for snow disaster risk assessment, risk early warning and snow disaster risk zoning in the Qinghai Tibet Plateau. The dataset contains four data files, named Mild Snowstorm. shp, Severe Snowstorm. shp, Severe Snowstorm. shp, and Extra Severe Snowstorm. shp. In the file attribute table, FID is the site number, and SUM is the number of days of snow disaster occurrence.

本数据集采用青藏高原109个地面气象站的逐日积雪观测数据，依据《气象灾害分级指标》（DB63/T372-2018）中的雪灾分级标准，统计了近20年来青藏高原轻度、中度、重度及特重度雪灾的发生日数。所构建的雪灾数据集可为青藏高原雪灾风险评估、风险预警以及雪灾风险区划提供数据支撑。本数据集包含四个SHP矢量文件（Shapefile），分别命名为Mild Snowstorm.shp、Moderate Snowstorm.shp、Severe Snowstorm.shp以及Extra Severe Snowstorm.shp。在文件属性表中，FID为站点编号，SUM为雪灾发生日数。
