Saturn's auroral emission from the main oval is the signature of the interaction between the planetary magnetosphere and the solar wind. However, widespread IR and dim UV auroral emissions exist at lower latitudes that map to Saturn's inner and middle magnetosphere. These emissions are the signature of the field-aligned current system which couples the planet's upper atmosphere to its magnetosphere. We present a time-independent model of the current system driven by the radial transport of Enceladusgenic plasma in Saturn's magnetosphere based on torque balance and conservation of angular momentum. The model self-consistently includes the effects of field-aligned potentials using a currentvoltage relation that accounts for the centrifugal confinement of the magnetospheric plasma and a variable ionospheric Pedersen conductance. The ionospheric conductances are derived from an ionospheric model coupled to an energy deposition module. The predicted field-aligned currents and auroral emission locations and intensities will be compared with Cassini and ground-based observations. We will then compare the current systems driven by radial transport at Saturn and Jupiter.
