The uwsfbcvm velocity model describes 3D seismic P- and S-wave velocities from a tomographic inversion for crustal structure in the San Francisco Bay region. The inversion used a modified version of the code by Fang et al. (JGR, 2016), which inverts both body-wave arrival times and surface-wave dispersion measurements for 3D P- and S-wave velocity structure simultaneously with determining earthquake locations.
