AB: We explore the possibility of electron acceleration by inertial Alfven waves in Jupiter's upper ionosphere. We discuss our results in the light of the results from Crary [1997] who investigated electron acceleration at the Io torus boundary. We show that electron acceleration by Alfven waves is possible in both regions and improve upon Crary's results by incorporating a more accurate plasma model along the Jupiter-Io flux tube. Furthermore, we suggest that resonant eigenmodes in Jupiter's ionosphere (~30 Hz) may of the source of modulation of S-bursts. Since the Alfven wave eigenmode phenomena and electron acceleration are seen on Earth, we rely heavily on analogy with earth-based observations to advance our models.
