Summary

A mathematical model of isostatic anomaly potential of the earth is presented. These anomalies must provide an accurate index of subsurface anomalous mass distribution in the earth. It is demonstrated that the isostatic reduction is not critical for low-degree spherical harmonic solutions of satellite-determined geopotential. The correction does become important, however, for higher-degree harmonic solutions of geopotential, more so for those derived from low-altitude orbits.
