The deuterium abundance in Jupiter and Saturn from ISO-SWS observations
Observations with the Short Wavelength Spectrometer (SWS) onboard the Infrared Space Observatory (ISO) are used to determine the D/H ratio in Jupiter's and Saturn's atmospheres. The D/H ratio isExpand
Photochemistry of Saturn's Atmosphere: I. Hydrocarbon Chemistry and Comparisons with ISO Observations
To investigate the details of hydrocarbon photochemistry on Saturn, we have developed a one-dimensional diurnally averaged model that couples hydrocarbon and oxygen photochemistry, molecular and eddyExpand
Titan's atmosphere from Voyager infrared observations
Abstract We have studied the 900–1200 cm−1 range in three different selections of ∼30 Voyager 1 IRIS spectra recorded in Titan's equatorial region. In particular, we have reanalyzed the 8.6-μmExpand
External supply of oxygen to the atmospheres of the giant planets
The detection of gaseous H2O in the upper atmospheres of Saturn, Uranus and Neptune is reported by infrared spectroscopy and may help to constrain the injection rate and possible activity of distant icy objects in the Solar System. Expand
Photochemistry and diffusion in Jupiter's stratosphere: Constraints from ISO observations and comparisons with other giant planets
[1] We have developed a one-dimensional, diurnally averaged, photochemical model for Jupiter's stratosphere that couples photodissociation, chemical kinetics, vertical diffusion, and radiativeExpand
Rain, winds and haze during the Huygens probe's descent to Titan's surface
Spectra and high-resolution images obtained by the Huygens Probe Descent Imager/Spectral Radiometer instrument in Titan's atmosphere reveal the traces of once flowing liquid, and like Earth, the brighter highland regions show complex systems draining into flat, dark lowlands. Expand
Near-infrared light from Venus' nightside - A spectroscopic analysis
Abstract We have simulated near-infrared spectra of the emission from Venus' nightside with a radiative transfer program that allows for emission, absorption, and scattering by atmospheric gases andExpand
Carbon Monoxide on Jupiter: Evidence for Both Internal and External Sources
Abstract Thirteen lines of the CO band near 4.7 μm have been observed on a jovian hot spot at a resolution of 0.045 cm−1. The measured line profiles indicate that the CO mole fraction is 1.0±0.2 ppbExpand
A time-dependent radiative model of HD 209458b
We present a time-dependent radiative model of the atmosphere of HD 209458b and investigate its thermal structure and chemical composition. In a first step, the stellar heating profile and radiativeExpand
Titan's Atmosphere from Voyager Infrared Observations: IV. Latitudinal Variations of Temperature and Composition
Abstract We have analyzed nine Voyager 1 infrared spectral averages covering Titan's disk from 53°S to 70°N. By use of radiative transfer modeling we have determined the thermal profiles and meanExpand
