An exercise of combining tide gauge and GPS results to derive trends in sea level G. Wöppelmann, B. Martín, M-N. Bouin, Z. Altamimi • Considering the major advances recently made in • Absolute antenna phase centre corrections for both GPS satellites and receivers • (IGSMAIL-5272, Gendt 2005) • Troposphere VMF or GMF mapping function (Boehm et al. 2005) • Atmospheric pressure loading corrections (Tregoning and van Dam 2005) • RF network extension to 92 IGb00 RF stations (IGSSTATION-352, Ferland 2005) • New ITRF2005 datum (Altamimi) • Approach of time series combination of coordinates solutions (Altamimi et al 2002) • we started to reprocess backwards GPS data (from 2005.7 to 2001.4) • and • we carried out an exercise of combining TG and GPS results • to derive GPS-corrected TG trends
