  Jupiter's banded appearance may appear unchanging to the casual observer, but
closer inspection reveals a dynamic, ever-changing system of belts and zones
with distinct cycles of activity. Identification of these long-term cycles
requires access to datasets spanning multiple jovian years, but explaining them
requires multi-spectral characterization of the thermal, chemical, and aerosol
changes associated with visible color variations. The Earth-based support
campaign for Juno's exploration of Jupiter has already characterized two
upheaval events in the equatorial and temperate belts that are part of
long-term jovian cycles, whose underlying sources could be revealed by Juno's
exploration of Jupiter's deep atmosphere.
