We discuss preliminary results of a study of the dynamics of the solar atmosphere including a first space based investigation of k-omega phase difference spectra between velocity and intensity perturbations. The data, including simultaneous line shift, line depth, and continuum intensity measurements at disk center, have been obtained from a MDI time series in its high resolution mode. Line depth and continuum intensity are used to calculate the line intensity which is the more frequently used parameter in phase difference studies. We compare the results to ground based observations.
