UNDER PROGRAM NNX15AJ41G UNIVERSITY OF CALIFORNIA AND NASA GSFC PROPOSED TO ACQUIRE NEW INFRARED OBSERVATIONS OF JUPITER AT HIGH SPECTRAL AND SPATIAL RESOLUTION TO ANSWER THE FOLLOWING FUNDAMENTAL SCIENTIFIC QUESTIONS: 1. WHAT IS THE VERTICAL STRUCTURE AND HORIZONTAL DISTRIBUTION OF WATER CLOUDS ON JUPITER? 2. WHAT IS THE ABUNDANCE AND VERTICAL PROFILE OF GASEOUS H2O NH3 AND PH3 IN JUPITER'S TROPOSPHERE? THE TEAM HAS USED INFRARED SPECTROMETERS ON NASA S INFRARED TELESCOPE FACILITY (IRTF/CSHELL AND IRTF/ISHELL) AND AT THE KECK OBSERVATORY (KECK/NIRSPEC). THESE GROUND-BASED OBSERVATIONS DIRECTLY SUPPORT THE JOVIAN INFRARED AURORAL MAPPER (JIRAM) ON THE JUNO SPACECRAFT AND ARE COMPLEMENTARY TO THE MICROWAVE RADIOMETER (MWR) ON JUNO. THE OBSERVATIONS PERMIT COMPARISONS OF NH3 AND H2O DERIVED FROM RADIO OBSERVATIONS USING THE EXPANDED VERY LARGE ARRAY (EVLA) AS WELL AS WITH IN-SITU MEASUREMENTS OF THE GALILEO PROBE ENTRY SITE. ADDITIONAL IMAGING OBSERVATIONS HAVE BEEN ACQUIRED SIMULTANEOUSLY WITH THE SPECTRAL OBSERVATIONS PROPOSED FOR NNX15AJ41G SO THIS PROPOSAL SEEKS FUNDING TO ANALYZE AND PUBLISH THESE ADDITIONAL IMAGING DATA. INCLUSION OF THE IMAGING DATA ACQUIRED AT A WAVELENGTH OF 4.7 MICRONS USING THE NIRI INSTRUMENT AT GEMINI NORTH WILL BENEFIT NNX15AJ41G BY PROVIDING CONTEXT FOR LONG-SLIT SPECTROSCOPY BY IMPROVING NAVIGATION OF SPECTRAL TRACES AND BY ENABLING COMPARISON BETWEEN THERMAL INFRARED AND OTHER REMOTE SENSING DATASETS OBTAINED DURING THE JUNO MISSION. THE PROPOSED EFFORT INCLUDES ACQUISITION OF NEW INFRARED IMAGING DATASETS OVER THE REMAINDER OF THE JUNO MISSION (JUNO IS PLANNED TO DEORBIT ON 30 JULY 2021).
