Continuity of ice sheet mass loss in Greenland and Antarctica from the GRACE and GRACE Follow-Onmissions
Abstract We examine data continuity between the GRACE and GRACE-FO missions over Greenland and Antarctica using independent data from the mass budget method (MBM) which calculates the difference between ice sheet surface mass balance and ice discharge at the periphery. For both ice sheets, we find c...

A cumulative mass gain of 980 Gigatonnes in Queen Maud Land since 2009, however, led to a pause in the acceleration in mass loss from Antarctica after 2016.
