Abstract

In this paper we present results from modeling the Earth’s gravitational field over the northern part of South-America using spherical wavelets. We have applied our analysis to potential data that we derived from CHAMP using the energy balance method, and to terrestrial gravity anomalies. Our approach provides a regional correction to the EGM96 reference gravity field, expressed in various detail levels, which are partly determined by the satellite data and partly by the terrestrial data.
