By following the trajectories of a large number of particles we capture the seasonal variations of the density and spatial distributions of dust in Saturn's E‐ring. We have used an optimized set of parameters from our earlier azimuthally symmetric ring model [ Juhász and Horányi , 2002] to match remote sensing, and in situ observations as well. The model will be tested by the upcoming Cosmic Dust Analyzer (CDA) measurements onboard Cassini . It will be useful to find regions in the E‐ring where the source moon of the detected dust grains can be identified. In these regions CDA measurements of the chemical composition of the dust particles will enable us to learn about the surface properties of their moon of origin.
