Fig. 8From: The influence of Antarctic ice loss on polar motion: an assessment based on GRACE and multi-mission satellite altimetryPolar motion excitation functions for the entire AIS (black) and for the subregions WAIS (blue), EAIS (green) and APIS (red) derived from gravimetry and altimetry solutions via least squares adjustment. The corresponding piecewise linear trends of the time spans 2003-2005, 2006-2008, 2009-2012 and 2013-2015 are providedBack to article page
