Abstract

We investigate the smoothing effect of the topographical correction applied to various types of the gravity anomalies commonly used in gravimetric geoid modelling. In particular, we compare the correlation of gravity anomalies with respect to the elevation of observation points, and the contribution of the local and regional topography on the roughness of gravity anomalies. The numerical experiment is conducted using the observed free-air gravity anomalies over the regional area of study which comprises a rough part of the American Rocky Mountains. The comparison is done for various types of the Bouguer gravity anomalies and the no-topography gravity anomalies. Results reveal that the smoothing effect of the topographical corrections on the high-frequency signal of gravity anomalies is very similar, despite the magnitudes of the topographical corrections vary significantly.
