We propose to extend and enhance the Juno mission's scientific output by taking high-resolution images of Jupiter that will supplement the spatial and spectral coverage provided by the mission’s instruments. We will use NIRI to take AO-stabilized images over a range of methane and molecular-hydrogen absorption features at 1.59-2.28 µm, which together probe the cloud distribution in the ~0.06-0.8 bar pressure region. The observations will be made at key times that coincide with the closest approach of the Juno spacecraft to Jupiter (the perijoves), and the global maps produced by NIRI will allow the observations from the Juno spacecraft to be placed into context. This is especially important for the microwave (MWR) and CCD (JunoCam) instruments, which are restricted to narrow longitudinal swaths, and the near-infrared instrument (JIRAM), which is now restricted to high latitudes.
