Abstract

Ground—based and Earth-orbiting observations of planetary objects can give significant additional knowledge which complements the results derived from spacecraft in situ and remote sensing investigations. Studies of the Io plasma torus provide excellent examples of this synergy. For a variety of reasons, Voyager measurements left several contradictions or uncertainties. Over the past years, particularly since the founding of the International Jupiter Watch in 1986, observers have chipped away at these contradictions to give a clearer picture of the composition, structure and variability of the torus. We provide a review of the most recent observations (concentrating on areas where ground-based measurements have contributed the most) and show that revisions to several commonly accepted paradigms must now be considered.
