Juno ingress and egress occultations will provide temperature profiles at northern [60-70N] and southern [25-50S] latitudes with excellent vertical resolution, but lacking in spatial and temporal context. Inversions of MIRSI multi-wavelength global imaging will provide good spatial context for occultation locations, but lacks good vertical resolution. Such an opportunity to combine these methods may not arise again until the 2030s with the JUICE mission. In addition, MIRSI thermal maps will be used to test theories that [i] microwave contrasts detected by Juno in the weather layer are largely driven by temperatures; and [ii] extend the long-term record of belt/zone variability on this archetypal giant.
