In this contribution, we provide updated results from our method and present further sensitivity tests to assess the performance of the technique. We extend our analysis in time for Jason-2 mission, and provide results for the candidate RGDR data for the TOPEX mission. We investigate strategies for minimising residual noise between the offshore altimeter comparison point and the coastal tide gauge sites, as well as assess the influence of applying the new ULR6 GPS based estimates of vertical land motion. We conclude with an assessment of the influence of the estimated bias drift corrections on the inferred rate of GMSL rise and its variation over the ~23 year record.
