The oceanographic community has access to near 14 years of altimetric data ranging fi om GEOSAT in 1985-1989 to the current TOPEX/Poseidon and ERS-2 missions. For sealevel change studies careful validation is required to avoid contamination of the results by spurious non-oceanographic effects. In this study we first utilise in situ tide gauge data to monitor stability of the TOPEX/Poseidon data base. This series is linked to both ERS satellites by dual satellite crossovers. The analysis is then extended to incorporate GEOSAT ERM data through tide gauge enhanced dual satellite crossovers with TOPEX. Results of the stability analysis are used to consider global mean sea-level change over the period 1986-1998.
