Numerical Testing of an Altimeter Reduction Method
Abstract
Tests are reported for a method of recovering improved gravity anomaly information in a local area of the ocean using altimeter-derived geoid height information in the local area. The tests were conducted to investigate the accuracy with which the gravity field can be recovered with altimeter data of 1 to 2 meter accuracy, the level of accuracy of the GEOS-C altimeter. Computation of detailed geoid heights from satellite data is outlined, and tests made with the GEM 4 satellite are described. It is shown that recovery of a more detailed gravity field than that provided by satellite gravity data is possible with the proposed method.
