全球冰湖编目数据集

气候变化加速了冰川的大范围退缩，导致冰湖广泛发育。掌握全球冰湖空间分布的整体情况，是监测其溃决灾害的重要基础。本数据采用半自动制图方法并实施严格质量控制，对全球范围内（不含南极和格陵兰冰盖/冰原）面积≥0.01 km2的冰湖进行编目，共识别出 117352 个冰...

Climate change has accelerated large-scale glacier retreat, leading to the widespread formation of glacial lakes. Obtaining a comprehensive overview of the global spatial distribution of glacial lakes is a critical foundation for monitoring glacial lake outburst disasters. This dataset adopts semi-automatic mapping methods and implements strict quality control to inventory glacial lakes with an area ≥0.01 km² across the globe (excluding the Antarctic and Greenland ice sheets/ice caps), and a total of 117,352 glacial lakes have been identified...
