Journal ArticleDOI
Superrotation of Venus' atmosphere analyzed with a full general circulation model
Sébastien Lebonnois,Frédéric Hourdin,Vincent Eymet,Audrey Crespin,Richard Fournier,François Forget +5 more
TL;DR: In this article, a general circulation model (GCM) was developed for the Venus atmosphere, from the surface up to 100 km altitude, based on the GCM developed for Earth at their laboratory.
Journal ArticleDOI
Density and temperatures of the upper Martian atmosphere measured by stellar occultations with Mars Express SPICAM
François Forget,Franck Montmessin,Jean-Loup Bertaux,Francisco Gonzalez-Galindo,Sébastien Lebonnois,Eric Quémerais,Aurélie Reberac,Emmanuel Dimarellis,Miguel Lopez-Valverde +8 more
TL;DR: In this paper, the authors presented one Martian year of observations of the density and temperature in the upper atmosphere of Mars (between 60 and 130 km) obtained by the Mars Express ultraviolet spectrometer Spectroscopy for Investigation of Characteristics of the Atmosphere of Mars.
Journal ArticleDOI
Three-dimensional modeling of ozone on Mars
TL;DR: In this paper, the first three-dimensional model simulations of ozone on Mars were presented, which showed significant deviations from the classical picture of a global anticorrelation between ozone and water vapor columns, related to substantial orbital variations in the O3 vertical distribution.
Journal ArticleDOI
The Latitudinal Distribution of Clouds on Titan
Pascal Rannou,Pascal Rannou,Franck Montmessin,Franck Montmessin,Frédéric Hourdin,Frédéric Hourdin,Sébastien Lebonnois,Sébastien Lebonnois +7 more
TL;DR: A general circulation model of Titan is developed that identifies and explains the formation of several types of ethane and methane clouds, including south polar clouds and sporadic clouds in temperate regions and especially at 40° in the summer hemisphere.
Journal ArticleDOI
