Illustration of steps in our method to convert dynamic models into seismic velocity models and account for the parameterization and resolution of S40RTS. a Dynamic model, where δ lnρ=3.8%, showing temperature and composition fields. b Predicted seismic wavespeed model showing δ lnVs variations with respect to the radial average. c Reparameterized model of δ lnVs on the basis of S40RTS. d Recovered δ lnVs after accounting for damping and uneven sampling of S40RTS. The geographic location of depth slice is provided in by the black vertical line through the globe
