中国北方GNSS气象观测业务站网积雪深度数据集(2013-2022)

本数据集提供我国北方52个GNSS地基站点历史积雪深度。数据集时间跨度为2013-2022年，空间范围覆盖25° ~ 55° N/70° ~ 140° E，时间分辨率为24小时、12小时和2小时（个别站点），空间分辨率代表站点周围约1000m2。数据集基于中国气象局气象探测中心建设的GNSS/MET业务站点原始观测数据研制。

This dataset provides historical snow depth data from 52 ground-based GNSS stations in northern China. The dataset spans the period from 2013 to 2022, with a spatial extent of 25°N–55°N and 70°E–140°E. The temporal resolutions are 24 hours, 12 hours, and 2 hours (for individual stations), and the spatial resolution corresponds to an area of approximately 1000 m² surrounding each station. This dataset was developed based on the original observational data from operational GNSS/MET stations constructed by the Meteorological Observation Center of the China Meteorological Administration.
