High Spatial Resolution of GRACE-Derived Ice Mass Change Reveals Glacier-Scale Mass Loss in Greenland Ice Sheet

Zhuoya Shi, Zemin Wang, Baojun Zhang, Manman Luo et autres

The Gravity Recovery and Climate Experiment (GRACE) and its follower GRACE-Follow On (GRACE-FO) act as a reliable tool to detect the Earth's surface mass change. However, its discontinuity between GRACE and GRACE-FO limits its applicability for long term analysis. Its coarse spatial …
