Antarctic Ice Mass Change (2003-2016) Jointly Estimated by Satellite Gravimetry and Altimetry
Accurate estimation of ongoing Antarctic ice mass change is important to predict future ice mass loss and subsequent sea level rise. Over the past two decades, Antarctic ice mass changes have been observed by the gravity recovery and climate experiment (GRACE) gravity mission, but the low spatial re...
