AB: We present three-dimensional plasma simulations of the interaction of Saturn's magnetosphere with the gas plumes originating near Enceladus' south pole. The pronounced north-south asymmetry of Enceladus' gas environment drives an electric current system which couples both the northern and southern hemispheres of Enceladus. We updated our model to numerically include this feature. In our presentation we will compare our model results with the magnetic field and neutral gas observations of Cassini's flybys at Enceladus to further constrain properties of Enceladus' gas plumes.
