The coupled GRACE/GIA evaluation of the Antarctic ice mass loss is unreliable
GRACE does not measure any ice sheet thickness but only gravity. Similarly to the computation of the global mean sea level (GMSL), the computation of the ice sheet thickness, follows a large number of assumptions. As a result, the actual inaccuracy of the Antarctic ice sheet thickness computation is...
