The Roadmap to 4D Earth model will be written with the outcomes of the various proposed sensitivity analysis done in the coming two years. Each study will analyze which type of modelling is best to connect to the large inversion methodology for the 3D Earth extension.
Moreover, we will have a thorough discussion on the best way to approach a consistent definition for the viscosity in all the different dynamic models. Special attention will be given on the vision about how to incorporate consistent uncertainty estimates of the model.
