Zusammenfassung:	Systems, methods, and media for modeling and filtering noise in seismic surveys are disclosed. Methods, systems, and computer program products in accordance with the present disclosure perform operations including obtaining seismic information of a region resulting from a source waveform applied to the region. The operations also include obtaining an estimate of visco-elastic properties of a near-surface of the region. The operations further include determining an estimate of propagation of guided waves in the region based on the estimate of visco-elastic properties of a near-surface of the region. Additionally, the operations include determining a model of the guided waves in the near-surface of the region using the estimate of propagation of the guided waves and an estimate of the source waveform. Moreover the operations include determining a filtered output of the seismic information by removing the model of the guided waves from the seismic information.
