Wong PROGRAM_INV3 Tilak Hewagama PROGRAM_INV4 Charles Goullaud PROGRAM_INV5 Glenn Orton PROGRAM_SCICAT major planets / satellites PROGRAM_ABSTRACT_BEG We propose to address two science questions: 1] Which cloud layers are responsible for the dramatic change in appearance in Jupiter's North Equatorial Belt [NEB] in the past 4 years; 2] what is the gas composition and cloud structure of Jupiter along the ground-track of the Juno microwave radiometer [MWR]? We plan to use iSHELL to measure gaseous H2O, NH3, and water clouds in the NEB, the northern hemisphere, and the Great Red Spot. One iSHELL wavelength setting will cover Jupiter's entire 5-micron window. PROGRAM_ABSTRACT_END
