:summary = "The WUS-CAMH-2015 shear velocity model combines spatially interpolated/smoothed receiver functions, surface-wave dispersion and gravity observations through a 3D simultaneous inversion to image the subsurface S-wave velocity structure of the western U.S. region. Data include 3608 interpolated P-wave receiver functions, 900 Rayleigh-wave group velocity dispersion curves, and wavenumber filtered Bouguer gravity observations. Constrained by simplified receiver functions and multiple geophysical observations, the velocity model is a reliable starting point for more detailed seismic investigations." ;
