Summary
SPani (Tesoniero et al., 2015) is a joint model of radially anisotropic P- and S-velocity variation of the whole mantle based on the inversion of fundamental Rayleigh and Love surface waves up to the sixth overtone and major P- and S-body wave phases. P- and S-sensitive data are coupled in the inversion by Rayleigh wave data and a mineral physics based regularization term on the relationship between S- and P-velocity variation. This page contains supplemental information on this model’s resolution.
