Near-Infrared atmospheric modelling of Jupiter's South Equatorial Belt (SEB) observed with AAT/IRIS2

Abstract

Near-Infrared spectra of Jupiter's South Equatorial Belt (SEB) with AAT/IRIS2 in H and K bands at a resolving power of R~2400 have been obtained. By creating line-by-line radiative transfer models with the latest improved spectral line data for ammonia and methane (HITRAN2016), we derive best models of cloud/haze parameters in Jupiter's South Equatorial Belt. The modelled spectra fit the observations well except for small, isolated discrepancies in the trough region of H2-H2 collision-induced-absorption around 2.08 {\mu}m and the methane absorption level between 2.16 and 2.19 {\mu}m in K band and at the high pressure methane window between 1.596 to 1.618 {\mu}m in H band.
