Titan's surface and atmosphere from Cassini/VIMS data with updated methane opacity

2013

International audience; We present an analysis of Titan data acquired by the Cassini Visual and Infrared Mapping Spectrometer (VIMS), making use of recent improvements in methane spectroscopic parameters in the region 1.3-5.2 μm. We first analyzed VIMS spectra covering a 8 × 10-km2 area near the Huygens landing site in order to constrain the single scattering albedo (ω0) of the aerosols over all of the VIMS spectral range. Our aerosol model agrees with that derived from Huygens Probe Descent Imager/Spectral Radiometer (DISR) in situ measurements below 1.6 μm. At longer wavelengths, ω0 steadily decreases from 0.92 at 1.6 μm to about 0.70 at 2.5 μm and abruptly drops to about 0.50 near 2.6 μm…

Methane in Titan's atmosphere: from fundamental spectroscopy to planetology

2009

The methane molecule (CH4) is relatively abundant in the Universe and in particular in our Solar System. On Earth, it is the main compound of natural gas and is also the second greenhouse gas of anthropic origin. On Saturn's satellite Titan it plays a role similar to water on Earth and leads to a complex chemistry.

Le méthane dans l’atmosphère de Titan - De la spectroscopie fondamentale à la planétologie

2008

Le methane (CH4) joue sur Tian, le plus gros satellite de Saturne, un role similaire a celui de l'eau sur Terre. Il y est de plus a l'origine d'une chimie organique complexe. La spectroscopie etant la technique privilegiee pour mesurer le CH4 dans les atmospheres planetaires, des modeles precis de l'absorption de la lumiere par cette molecule doivent etre developpes. Les resultats recents obtenus dans ce domaine a l'Institut Carnot de Bourgogne, en collaboration etroite avec des planetologues, permettent notamment de contribuer a l'interpretation des resultats de la mission Cassini-Huygens.
