Several recent altimeter data reprocessing/re-calibration analyses have been completed for both the current Sentinel-6 Michael Frielich (F08 version) mission, and the historical TOPEX/Jason time series including TOPEX/Poseidon retracking and radiometer re-calibrations for Jason-2 and Jason-3. The GSFC orbit standard std2006 has also been revised to include updated time variable gravity forward modeling. In this presentation we re-estimate Global Mean Sea Level (GMSL) and assess the accuracy of the revised 30+ year sea surface height time series via tide gauge comparisons and ocean mass budget analyses.
