In this work, we focused on the longitudinal region covering the three ovals having higher contrast at 5 μm, i.e., between 120°W and 60°W in System III coordinates. We used the JIRAM's full spectral capability in the range 2.4-3 μm together with a Bayesian data inversion approach to retrieve maps of column densities and altitudes for an NH<SUB>3</SUB> cloud and an N<SUB>2</SUB>H<SUB>4</SUB> 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. <P /> | URI: | http://hdl.handle.net/20.500.12386/26859 | URL: | https://agupubs.onlinelibrary.wiley.com/doi/full/10.1002/2017GL072940 | ISSN: | 0094-8276 | DOI: | 10.1002/2017GL072940 | Bibcode ADS: | 2017GeoRL..44.4660S | Fulltext: | embargo_21200713 |
