Abstract
We have combined die most recent Pioneer Venus Orbiter (PVO) and Magel lan (MGN) data with the earlier 1978-1982 PVO data set to obtain a new 60th degree and order spherical harmonic gravity model and a 120th de gree and order spherical harmonic topography model. Free-air gravity m aps are shown over regions where the most marked improvement has been obtained (Ishtar-Terra, Alpha, Bell and Artemis). Gravity versus topog raphy relationships are presented as correlations per degree and axes orientation.
