Abstract
A point mass model is used to predict oceanic gravity anomalies from simulated altimeter data. Gravity anomalies from land areas are also combined with altimetry as hybrid data inputs to the mathematical model. The geocentric radii of the point mass anomaly sets are determined by use of the ‘best r‐formula’ of Hardy and Göpfert. Test control data, consisting of 1° × 1° mean free air gravity anomalies in a 30 × 30 block, are recovered with a standard deviation of about 20 mGal., using the hybrid data observations as well as altimeter observations alone. Highly significant computational advantages are evident in comparison with other methods.Keywords
