Summary
S362ANI, Kustowski, Ekstrom and Dziewonski (2008) , has its radial anisotropy confined to the uppermost mantle (that is, since the anisotropy is parameterized with only the four uppermost splines, it becomes very small below a depth of 250 km, and vanishes at 410 km). The 1-D reference model is “STW105”../../referencemodels/emc-stw05 .
