Mass change of the Antarctic ice sheet inferred from ICESat and CryoSat-2
This study examined the mass change of the Antarctic ice sheet (AIS) based on ICESat and CryoSat-2 observations. We estimated the AIS exhibited mass losses of −101±15 Gt·a−1 during the ICESat period (Sept–Nov 2003 to Sept–Oct 2009) and −186±55 Gt·a−1 during the CryoSat-2 period (Jan 2011 to Dec 2015...

We estimated the AIS exhibited mass losses of −101±15 Gt·a−1 during the ICESat period (Sept–Nov 2003 to Sept–Oct 2009) and −186±55 Gt·a−1 during the CryoSat-2 period (Jan 2011 to Dec 2015).
