英文摘要 | During the first perijove passage of the Juno mission, the Jovian InfraRed Auroral Mapper (JIRAM) observed a line of closely spaced oval features in Jupiter's southern hemisphere, between 30 degrees S and 45 degrees S. In this work, we focused on the longitudinal region covering the three ovals having higher contrast at 5m, i.e., between 120 degrees W and 60 degrees W in System III coordinates. We used the JIRAM's full spectral capability in the range 2.4-3m together with a Bayesian data inversion approach to retrieve maps of column densities and altitudes for an NH3 cloud and an N2H4 haze. The deep (under the saturation level) volume mixing ratio and the relative humidity for gaseous ammonia were also retrieved. Our results suggest different vortex activity for the three ovals. Updraft and downdraft together with considerations about the ammonia condensation could explain our maps providing evidences of cyclonic and anticyclonic structures. |
