A joint inversion of P-wave first arrivals, surface wave dispersion curves and reflectivity image along picked horizons is proposed for estimating a high resolution P-wave (and S-wave) velocity model of the near-surface. The three inversion datasets are combined in a stochastic optimization process through normalization of cost function terms accounting for different data domains. The resulting velocity model is geologically consistent and reconciles P and S-wave velocities and shallow reflectivity as well.
