Abstract:
We compare Jupiter observations made around 27 August 2016 by Juno's JunoCam, Jovian
Infrared Auroral Mapper (JIRAM), MicroWave Radiometer (MWR) instruments, and NASA's Infrared
Telescope Facility. Visibly dark regions are highly correlated with bright areas at 5 ?m, a wavelength
sensitive to gaseous NH3 gas and particulate opacity at p <=5 bars. A general correlation between 5-?m
and microwave radiances arises from a similar dependence on NH3 opacity. Significant exceptions are
present and probably arise from additional particulate opacity at 5 ?m. JIRAM spectroscopy and the MWR
derive consistent 5-bar NH3 abundances that are within the lower bounds of Galileo measurement
uncertainties. Vigorous upward vertical transport near the equator is likely responsible for high NH3
abundances and with enhanced abundances of some disequilibrium species used as indirect indicators of
vertical motions.
