a, Backscattered energy (D−1.5) as a function of correlation length (a) and root-mean-square velocity perturbation (ε). Stars mark the (a, ε) pairs used in generating synthetic envelopes shown in b. b, Synthetic envelopes from scattering models with the same diffusivity D but different (a, ε) pairs marked as stars in a.
