A seismic data processing method for predicting and removing unwanted near-surface noise, e.g. refracted waves and surface waves, from composite seismograms acquired with multiple, encoded seismic sources in which the time records from the different sources overlap or interfere. Surface-consistent properties are determined (403) for the near-surface noise and used to predict the noise waveforms (404) for the composite simultaneous-source seismograms, and the waveforms are then subtracted or adaptively subtracted (406) from the seismograms.
