Monthly glacier mass changes from CryoSat-2 radar altimetry

We generate a record of ice loss across glaciers globally for the first time from CryoSat-2 swath interferometric radar altimetry. CryoSat-2’s orbital sub-cycle of 30 days allows us to resolve changes at high temporal resolution for Alaska, Arctic Canada North and South, Greenland periphery glaciers, Iceland, Svalbard, Franz Josef Land, Novaya Zemlya, Severnaya Zemlya, High Mountain Asia, Southern Andes and Antarctic periphery glaciers between 2010 and 2020.本研究首次基于CryoSat-2条带干涉雷达测高数据（swath interferometric radar altimetry）构建了全球冰川冰量损失记录。CryoSat-2的30天轨道亚周期，使得我们能够以高时间分辨率解析2010至2020年间阿拉斯加、加拿大北极南北区域、格陵兰周边冰川、冰岛、斯瓦尔巴群岛、法兰士约瑟夫地群岛、新地群岛、北地群岛、高亚洲（High Mountain Asia）、安第斯山脉南部以及南极周边冰川的冰量变化。
