Abstract
Geoid heights derived from GEOS‐3 radar altimeter measurements have been used to predict an ocean‐area gridded 1°×1° geoid height data base. These geoid heights are compared at 1°×1° grid intersections with similar values computed via spherical harmonic expansion, utilizing several different geo‐potential coefficient sets, and also with the Calibration Geoid which was computed using Stokes’ Integral and mean gravity anomalies. The gridded 1°×1° geoid height data base has been utilized to compute preliminary ocean‐area mean gravity anomalies. Comparisons are made between these preliminary 1°×1° mean gravity anomaly values and similar quantities computed from ship‐acquired gravity data.
