We have created (i) a new radially anisotropic reference Earth model, (ii) a new global model of the anisotropic shear-wave velocity in the mantle, and (iii) a shear-wave velocity model of the upper mantle beneath Eurasia. The data used in the inversions comprise surface-wave phase anomalies, long-period waveforms, and travel times of teleseismic body waves.
