Abstract:
The global water abundance in Jupiter is pivotal in understanding Giant-Planet formation and the delivery of volatiles throughout the solar system. The Microwave Radiometer (MWR) on board Juno provides the first measurements of Jupiter's deep atmosphere, down to ~250 bars in pressure. Li et al. (2020) reported the initial results from MWR on water abundance near Jupiter’s equatorial region. The discovery by Juno that Jupiter’s atmosphere is not well mixed at depth and displays significant variability with latitude suggests that water may vary with latitude even at depth. We present current plans and status for Juno’s investigation of water beyond equatorial latitudes including observation plans for Juno’s extended mission that will be able to observe Jupiter’s north polar region at improved resolution.
