1995/02/01 [Preliminary Marine Geoid](/missions/ers-2/sea-level-analysis/ers-1-preliminary-marine-geoid/) computed using four first months of the first ERS-1 repeat cycle. A significant improvement in the [altimeter residuals](/missions/ers-2/precise-orbit-determination/altimetry-processing/) can be observed: below 14 cm instead of 20 cm obtained using OSU-91A geoid. A jump of 40 cm can be observed in the ERS-1 [altimeter bias](/missions/ers-2/precise-orbit-determination/altimetry-processing/) due to the different reference ellipsoid associated with the new model
