Venus gravity anomalies and their correlations with topography

Abstract

This report provides a summary of the high‐resolution gravity data obtained from the Pioneer Venus Orbiter radio tracking data. Gravity maps, covering a 70° latitude band through 360° of longitude, are displayed as line‐of‐sight and vertical gravity. Topography converted to gravity and Bouguer gravity maps are also shown in both systems. Topography to gravity ratios are made over several regions of the planet. There are markedly different ratios for the Aphrodite area as compared to the Beta and Atla areas.
