Description: Research note
Abstract: After a review of related work, a first order connection between a spherical harmonics presentation of the disturbing potential at a height of 9 km above sea level and the anomalous potential at the earth's physical surface based on the theories of Pellinen, Moritz, and the author is facilitated. This is achieved by a topographic correction term applied to the potential at 9 km above sea level, which permits an analytical continuation between the thus modified potential and that expressed by F'aye anomalies at the earth's physical surface. In this way, the problem of analytical continuation of free air gravity anomalies is avoided. Furthermore, it is possible to reduce the remaining potential or gravity anomaly variance at 9 km above sea level, associated with higher order harmonics, by corresponding topographic corrections.
