Fig. 7From: The influence of Antarctic ice loss on polar motion: an assessment based on GRACE and multi-mission satellite altimetryDifferences of the combined solutions for polar motion excitation functions for AIS, APIS, WAIS and EAIS: arithmetic mean of the gravimetry solutions (blue), arithmetic mean of the altimetry solutions (green), aritmetic mean of the gravimetry and altimetry solutions (cyan), weighted adjustment of all gravimetry and altimetry solutions (red) with respect to the combined gravimetry solution LDCmgm90. Note the different ranges of the axis due to the different magnitudes of the signals in the different regionsBack to article page
