郴州市东江湖区段2015-2024地表水水质特征信息数据集

东江湖位于湖南省郴州市境内，是以发电、防洪、供水及旅游为主的国家重点水库。郴州市东江湖区段2015–2024年地表水水质特征信息数据集，基于Sentinel系列卫星影像反演获得，涵盖透明度、叶绿素a浓度、悬浮物浓度及浊度等关键水质参数。数据利用多时相Sentinel-2 MSI影像，经大气校正、云影去除、水体掩膜及反演模型计算生成，空间分辨率为10米，时间覆盖2015年至2024年。

Dongjiang Lake, located in Chenzhou City, Hunan Province, is a national key reservoir primarily serving power generation, flood control, water supply and tourism. The dataset of surface water quality characteristic information for the Dongjiang Lake section in Chenzhou City spanning 2015 to 2024 was derived via inversion of Sentinel series satellite images, covering key water quality parameters including transparency, chlorophyll-a concentration, suspended matter concentration and turbidity. This dataset was generated using multi-temporal Sentinel-2 MSI imagery through atmospheric correction, cloud shadow removal, water body masking and inversion model computation, with a spatial resolution of 10 meters and a temporal coverage from 2015 to 2024.
