The analysis of surface waves can be a powerful tool for characterising the near-surface down to penetration depth. In this framework, the surface wave analysis is part of the data processing workflow, and the surface waves are considered signal and not noise. After having extracted the information the surface waves carry, they become unwanted signal to be removed. The resulting near-surface model can be used for short- to long-wavelength statics and perturbation corrections, for velocity model building, and for better filter design which can take into account the complexity of near-surface phenomena.
