Gravity anomaly map.

The gravity anomaly maps presented here (Bouguer, isostatic and surface free-air) are derived from available Earth gravity models (EGM2008, DTU10) and include high resolution terrain corrections that consider the contribution of most surface masses (atmosphere, land, oceans, inland seas, lakes, ice caps and ice shelves).Gravity anomaly grids for the conterminous US Measurements of the gravitational field vary slightly from place to place due to the composition and structure of Earth's crust. These digital grids describe the isostatic residual and Bouguer anomaly for the conterminous US.The colors on this complete Bouguer gravity anomaly map (Bankey and others, 1995) represent gravity variations resulting from lateral density variations in the Earth.

This last term describes how fast the "vertical rate of change in gravity" is changing. However the success of this process depends upon adequate data spacing.

The higher-resolution of Mars gravity anomalies enabled us to refine the global map of the Martian crustal thickness. Assuming a bulk density of 2900 kg/m 3 for the crust, we were able to compute the Bouguer anomaly by subtracting the gravity predicted from topography from the GMM-3 solution.
