On the Pratt and Airy models of isostatic geoid undulations

Journal of Geodynamics, 1998
Abstract Usually the topographic-isostatic geoid undulation is derived by a downward continuation of the external potential to the geoid. Unfortunately, such an approach merely yields a fictitious potential at the continental geoid within the topographic masses.

Modifying Stokes' function to reduce the error of geoid undulation computations

Journal of Geophysical Research: Solid Earth, 1981
A comparison is made of the errors in determining the geoid undulation according to the conventional Molodenskii truncation theory and its modifications as suggested by Molodenskii (1958) and Meissl (1971). The undulation is assumed to be computed from gravity anomalies in a spherical cap and a finite set of harmonic potential coefficients (e.g., GEM 9

Ellipsoidal corrections for geoid undulation computations using gravity anomalies in a cap

Journal of Geophysical Research: Solid Earth, 1981
Ellipsoidal correction terms have been derived for geoid undulation computations when the Stokes equation using gravity anomalies in a cap is combined with potential coefficient information. The correction terms are long wavelength and depend on the cap size in which its gravity anomalies are given.

On the gravimetric undulations of the geoid and the deflections of the vertical

Geofisica pura e applicata, 1958
The author mentions the aims of the World-wide gravity project he established in the Ohio State University in Columbus, in 1950. He outlines the practical procedure of the gravimetric computations of the undulationsN and the vertical deflection components ξ and η and emphasizes that only by the global international cooperation and additional gravity ...
