英文摘要	Glacier melt in High Mountain Asia (HMA) is an indicator of climate change and has a major impact on the regional hydrology and freshwater supply. We determined the recent status of HMA glaciers based on the first analysis of Ice, Cloud, and Land Elevation Satellite-2 (ICESat-2) data. We used the Gravity Recovery and Climate Experiment (GRACE) and GRACE Follow-On (FO) data to complement ICESat-1,2 data and validate them independently. We find a good agreement between ICESat-1,2 and GRACE/GRACE-FO data, which demonstrates the high reliability of results. Based on our results, the continuous glacier mass change from 2003 to 2019 is −28 ± 6 Gt yr−1, which is more negative than stereo imagery-based studies. The regional variability of the glaciers ranges from −1.07 ± 0.10 m yr−1 in southeastern Nyaingentanglha to +0.16 ± 0.10 m yr−1 in West Kunlun. ICESat-2 data enable new insight into the continuous measurement of HMA glacier elevation change. © 2020. American Geophysical Union. All Rights Reserved.
