Summary
The Earth’s gravity signal reflects the density and mass distribution as well as the rotation of the Earth. It is dominated by the so-called central term of the Earth and its flattening at the poles. Medium to high frequency spectral components are induced by density anomalies and topographical masses.
A wide range of gravity anomalies are calculated for the Baden-Württemberg area, based on high-resolution terrestrial data. While the Free-air anomalies and Faye anomalies are clearly influenced by the topography, the Bouguer anomalies show a smoothed behavior. After applying the isostatic reduction, the variation of the anomalies decreases significantly. A comparison with anomalies derived from gravity field satellite missions clearly shows that the latter have a lower spatial resolution.
