Data Services Products: EMC-SPani-Supplemental Supplemental information on Earth model SPani

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.
