We present a new generation of dynamic model atmospheres for pulsating AGB stars based on a combined solution of hydrodynamics, frequency-dependent radiative transfer, and time-dependent dust formation. At present, we are performing a systematic study of the dependence of atmospheric structure, observable properties and mass loss on stellar parameters and pulsation properties. Preliminary results show a good agreement with observations and a considerable improvement compared to existing grey dynamical models.
