全球10km²以上自然湖泊水位-水量变化数据集（2003-2020年）

该数据集联合激光测高卫星ICESat及其第二代卫星ICESat-2形成长时序高程观测资料，结合全球水体面积数据对全球10 km2以上的自然湖泊水位-水量在近二十年（2003-2020）变化特征开展了定量研究，完善了湖泊水体范围、历年平均面积、研究时段水位-水量变化以及被ICESat/ICESat-2观测次数等信息，形成了完整可靠的全球10 km²以上湖泊在2003-2020年水位-水量变化的空间分布数据。包含了1个shapefile文件，为矢量数据。

This dataset combines long-term elevation observation data derived from the laser altimetry satellites ICESat and its second-generation successor ICESat-2, paired with global water area datasets to conduct a quantitative analysis of the water level and storage variation characteristics of global natural lakes with an area exceeding 10 km² over the past two decades (2003–2020). It supplements key information including lake water extents, annual average lake areas, water level and storage changes during the study period, and the number of observation records obtained by ICESat/ICESat-2, ultimately producing complete and reliable spatially distributed data on water level and storage changes of global natural lakes larger than 10 km² from 2003 to 2020. The dataset includes one shapefile, which is vector geospatial data.
