[S21-4-05] Integrating seismological and satellite gravity data for consistent 3D Earth models
Satellite data are an ideal tool for global modelling due to their spatial and temporal resolution. For example, the characteristics of satellite gravity gradients allow in combination with seismological models to study the lithosphere in a consistent manner with great detail, which is one of the aims of the ESA STSE “3D Earth".
In the integration of seismological models and satellite observation towards a consistent image of the crust and upper mantle in 3D certain challenges arise. For example, the consistency in resolution and accuracy of seismological and density models is often not provided. The spectral content of the models does not necessarily agree and there is a need for establishing common frames for joint analysis.
We discuss the limitations and sensitivities of different geophysical methods in the context of their imaging capability and in combination for forward and inverse modelling of the Earth's internal structure. Such analysis is the first step to assess the role and feedback of isostatic (lithospheric) and dynamic (deep Earth) effects in shaping the surface of the Earth.
