Raffinement des modèles géophysiques globaux de la Terre par assimilation de données gravimétriques satellitaires

Abstract : Today satellite-measured data have been increasingly using to understand the internal structure of the Earth. Moreover, the comparison between the gravitational effect measured by the gravimetric satellite GOCE and which computed from global earth models, enables the refinement of these latter. In this study, we conceive new geophysical models from these existing, whose gravitational effect is similar to the one measured. The analyses of differences between the Gravity Gradient Tensor components evaluated by satellites and these which are computed from our models, as regard the accuracy of satellite measurement precision, allow some modifications to take into account in our model’s conception. In other words, it means to refine these latter by gravimetric satellite data assimilation.
