Data Services Products: EMC-TX2011 A global shear-wave tomography model

Summary

TX2011 provides shear velocity perturbations with respect to the TX2011_ref reference model with the mean from the individual layers removed. The grid is not representative of the block size used in the inversion. The model assumes the crustal thickness is given by the Mooney, Laske and Masters crustal model, Mooney et al. (1998) , and thus velocity deviations in the upper most layer are with respect to a variable crustal thickness model.
