The UVS instrument on the Juno mission records far-ultraviolet reflected sunlight from Jupiter. These spectra are sensitive to the abundances of chemical species in the upper atmosphere and to the distribution of the stratospheric haze layer. We combine observations from the first 30 perijoves of the mission in order to study the meridional distribution of acetylene (C2H2) in Jupiter’s stratosphere. We find that the abundance of C2H2 decreases towards the poles by a factor of 2–4, in agreement… Expand

Jupiter in the Ultraviolet: Acetylene and Ethane Abundances in the Stratosphere of Jupiter from Cassini Observations between 0.15 and 0.19 μm
At wavelengths between 0.15 and 0.19 $\mu$m, the far-ultraviolet spectrum of Jupiter is dominated by the scattered solar spectrum, attenuated by molecular absorptions primarily by acetylene andExpand
Photochemistry, mixing and transport in Jupiter’s stratosphere constrained by Cassini
Abstract In this work, we aim at constraining the diffusive and advective transport processes in Jupiter’s stratosphere, using Cassini/CIRS observations published by Nixon et al. (2007,2010). TheExpand
Jupiter’s auroral-related stratospheric heating and chemistry I: Analysis of Voyager-IRIS and Cassini-CIRS spectra
Abstract Auroral processes are evident in Jupiter’s polar atmosphere over a large range in wavelength (X-ray to radio). In particular, previous observations in the mid-infrared (5–15 µm) have shownExpand
Meridional Variations of C2H2 and C2H6 in Jupiter's Atmosphere from Cassini CIRS Infrared Spectra
Hydrocarbons such as acetylene (C2H2) and ethane (C2H6) are important tracers in Jupiter’s atmosphere, constraining our models of the chemical and dynamical processes. However, our knowledge of theExpand
