Data Services Products: EMC-S2.9EA A global model with higher resolution in the upper mantle beneath Eurasia

Summary

S2.9EA, Kustowski, Ekstrom and Dziewonski (2008A) , laterally parametrize the upper-mantle structure beneath Eurasia using spherical splines with ˜2.9° spacing in Eurasia and ˜11.5° spacing elsewhere. The model is obtained from a combined data set of surface wave phase velocities, long-period waveforms and body-wave traveltimes. The 1-D reference model is STW105 .

Description

Name S2.9EA
Title A global model with higher resolution in the upper mantle beneath Eurasia calculated using STW105 as the 1-D reference model.

Sub Type Anisotropic (in the uppermost mantle) S velocities
Year 2008
Short Description   In this shear wave velocity model for the upper-mantle structure beneath Eurasia is parametrized laterally using spherical splines with ˜2.9° spacing in Eurasia and ˜11.5° spacing elsewhere. The model is obtained from a combined data set of surface wave phase velocities, long-period waveforms and body-wave traveltimes.
