The Composite Infrared Spectrometer observed Jupiter in the thermal infrared during the swing-by of the Cassini spacecraft. Results include the detection of two new stratospheric species, the methyl radical and diacetylene, gaseous species present in the north and south auroral infrared hot spots; determination of the variations with latitude of acetylene and ethane, the latter a tracer of atmospheric motion; observations of unexpected spatial distributions of carbon dioxide and hydrogen… Expand
Mid-infrared mapping of Jupiter’s temperatures, aerosol opacity and chemical distributions with IRTF/TEXES
Abstract Global maps of Jupiter’s atmospheric temperatures, gaseous composition and aerosol opacity are derived from a programme of 5–20 µm mid-infrared spectroscopic observations using the TexasExpand
The composition of Titan's stratosphere from Cassini/CIRS mid-infrared spectra
Abstract We have analyzed data recorded by the Composite Infrared Spectrometer (CIRS) aboard the Cassini spacecraft during the Titan flybys T0–T10 (July 2004–January 2006). The spectra characterizeExpand
Meridional Variations of C 2 H 2 in Jupiter's Stratosphere From Juno UVS Observations
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 theExpand
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
Aerosol influence on energy balance of the middle atmosphere of Jupiter
It is shown, based on observations from the NASA spacecraft Voyager and Cassini, that gases alone cannot maintain the global energy balance in the middle atmosphere of Jupiter, and a thick aerosol layer consisting of fluffy, fractal aggregate particles dominates the stratospheric radiative heating at middle and high latitudes.

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
Is the Stormy Weather of Jupiter is Comparable to Earth
The atmosphere of Jupiter is mainly made of molecular hydrogen and helium. The cloud pattern as found at different Jupiter belts and the vertical structure of its atmosphere are examined indicatingExpand
Composite infrared spectrometer (CIRS) on Cassini.
The Cassini spacecraft orbiting Saturn carries the composite infrared spectrometer (CIRS) designed to study thermal emission from Saturn and its rings and moons, an indispensable part of the payload providing unique measurements and important synergies with the other instruments. Expand
Chemical and Dynamical Processes in the Atmospheres of I. Ancient and Present-Day Earth II. Jupiter and Galilean Satellites III. Extrasolar \Hot Jupiters"
When exposed to stellar UV radiation, chemical processes will be governed not only by temperature/pressure but also the spectrum of the incoming dissociative photon flux; the system will approachExpand
Modelling the near-infrared spectra of Jupiter using line-by-line methods
We have obtained long-slit, infrared spectra of Jupiter with the Anglo-Australian Telescope in the K and H bands at a resolving power of 2260. Using a line-by-line, radiative transfer model with theExpand


Infrared Observations of the Jovian System from Voyager 1
The infrared spectroscopy and radiometry investigation has obtained spectra of Jupiter and its satellites between approximately 180 and 2500 cm–1 with a spectral resolution of 4.3 cm–1. The JupiterExpand
Cassini Imaging of Jupiter's Atmosphere, Satellites, and Rings
Findings on Jupiter's zonal winds, convective storms, low-latitude upper troposphere, polar stratosphere, and northern aurora are reported, including previously unseen emissions arising from Io and Europa in eclipse, and a giant volcanic plume over Io's north pole are described. Expand
Thermal profiles in the auroral regions of Jupiter
The temperature structure within the northern auroral region of Jupiter is studied by reanalyzing the Voyager 1/infrared interferometer and radiometer spectrometer (IRIS) spectra. The total measuredExpand
Images of Excited H3+ at the Foot of the lo Flux Tube in Jupiter's Atmosphere
The electrodynamic interaction between lo and the Jovian magnetosphere drives currents to and from the planet's ionosphere, where H3+ emission is excited, and data favor the unipolar inductor model of the lo interaction and provide insight into the source location and generation ofJovian decameter radio emission.

Possible infrared aurorae on Jupiter
Abstract We have observed infrared brightenings near the poles of Jupiter at 8 μm in early 1980. We suspect they are nonthermal in origin. These brightenings are apparently related to the auroralExpand
A pulsating auroral X-ray hot spot on Jupiter
High-spatial-resolution observations demonstrate that most of Jupiter's northern auroral X-rays come from a ‘hot spot’ located significantly poleward of the latitudes connected to the inner magnetosphere, invalidate the idea that jovian auroralX-ray emissions are mainly excited by steady precipitation of energetic heavy ions from the inner Magnetosphere.

An intense stratospheric jet on Jupiter
Maps of temperatures and winds with high spatial resolution, obtained from spacecraft measurements of infrared spectra of Jupiter's stratosphere, find an intense, high-altitude equatorial jet with a speed of ∼140 m s-1, whose spatial structure resembles that of a quasi-quadrennial oscillation.
