Fig. 9From: Comparison of non-tidal loading data for application in a secular terrestrial reference frameGeocentre motion contributions as computed for the combined loading of both GCTI20 (NTAL + NTOL + HYDL, red) and ESMGFZ (NTAL + NTOL + HYDL + SLEL, blue). For comparison, also the geocentre motion estimated by SLR is shown (grey). The time-series for GCTI20 and SLR have been shifted by 10 and 20 mm, respectivelyBack to article page
