Comparison of General Circulation Models of the Venus upper atmosphere
Antoine Martinez, Hiroki Karyu, Amanda Brecht +7
In the context of future Venusian missions, it is crucial to improve our understanding of Venus upper atmosphere through 3D modeling, notably for spacecraft orbit computation. This…
The effect of near-surface winds on surface temperature and dust transport on Venus
Maxence Lefèvre, Sébastien Lebonnois, Aymeric Spiga +1
The knowledge of the Venus near-surface atmosphere is sparse. Few spacecrafts landed on the surface and measured winds with amplitudes below 1 m/s. The diurnal cycle of the wind am…
Evaluation of new radio occultation observations among small satellites at Venus by data assimilation
Yukiko Fujisawa, Norihiko Sugimoto, Chi Ao +5
We conducted observing system simulation experiments (OSSEs) for radio occultation measurements (RO) among small satellites, which are expected to be useful for future Venus missio…
Latitudinal Variation of Clouds' Structure Responsible for Venus' Cold Collar
I. Garate-Lopez, Sébastien Lebonnois
Global Climate Models (GCM) are very useful tools to study theoretically the general dynamics and specific phenomena in planetary atmospheres. In the case of Venus, several GCMs su…
Validation of the IPSL Venus GCM Thermal Structure with Venus Express Data
Pietro Scarica, Itziar Garate-Lopez, Sebastien Lebonnois +4
General circulation models (GCMs) are valuable instruments to understand the most peculiar features in the atmospheres of planets and the mechanisms behind their dynamics. Venus ma…
3D Global climate model of an exo-Venus: a modern Venus-like atmosphere for the nearby super-Earth LP 890-9 c
Diogo Quirino, Gabriella Gilli, Lisa Kaltenegger +6
The recently discovered super-Earth LP 890-9 c is an intriguing target for atmospheric studies as it transits a nearby, low-activity late-type M-dwarf star at the inner edge of the…
Revealing the Mysteries of Venus: The DAVINCI Mission
James B. Garvin, Stephanie A. Getty, Giada N. Arney +36
The Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging (DAVINCI) mission described herein has been selected for flight to Venus as part of the NASA Discover…
Gravitational atmospheric tides as a probe of Titan's interior: Application to Dragonfly
Benjamin Charnay, Gabriel Tobie, Sébastien Lebonnois +1
Context: Saturn's massive gravity is expected to causes a tide in Titan's atmosphere, producing a surface pressure variation through the orbit of Titan and tidal winds in the tropo…
Characterising atmospheric gravity waves on the nightside lower clouds of Venus: a systematic analysis
J. E. Silva, P. Machado, J. Peralta +3
We present the detection and characterisation of mesoscale waves on the lower clouds of Venus using images from the Visible Infrared Thermal Imaging Spectrometer onboard the Europe…
Ariel: Enabling planetary science across light-years
Giovanna Tinetti, Paul Eccleston, Carole Haswell +313
Ariel, the Atmospheric Remote-sensing Infrared Exoplanet Large-survey, was adopted as the fourth medium-class mission in ESA's Cosmic Vision programme to be launched in 2029. Durin…
Venus upper atmosphere revealed by a GCM: II. Model validation with temperature and density measurements
Gabriella Gilli, Thomas Navarro, Sebastien Lebonnois +5
An improved high-resolution ground-to-thermosphere version of the Institut Pierre-Simon Laplace (IPSL) Venus General Circulation Model (VGCM), including non-orographic gravity wave…
Seasonal changes in the middle atmosphere of Titan from Cassini/CIRS observations: temperature and trace species abundance profiles from 2004 to 2017
Christophe Mathé, Sandrine Vinatier, Bruno Bézard +6
The Cassini/Composite InfraRed Spectrometer (CIRS) instrument has been observing the middle atmosphere of Titan over almost half a Saturnian year. We used the CIRS dataset processe…
The Physical Origin of the Venus Low Atmosphere Chemical Gradient
Daniel Cordier, David A. Bonhommeau, Sara Port +3
Venus shares many similarities with the Earth, but concomitantly, some of its features are extremely original. This is especially true for its atmosphere, where high pressures and…
Long-term variations of Venus' 365-nm albedo observed by Venus Express, Akatsuki, MESSENGER, and Hubble Space Telescope
Yeon Joo Lee, Kandis-Lea Jessup, Santiago Perez-Hoyos +16
An unknown absorber near the cloud top level of Venus generates a broad absorption feature from the ultraviolet (UV) to visible, peaking around 360 nm, and therefore plays a critic…
Seasonal evolution of temperatures in Titan's lower stratosphere
M. Sylvestre, N. A. Teanby, J. Vatant d'Ollone +4
The Cassini mission offered us the opportunity to monitor the seasonal evolution of Titan's atmosphere from 2004 to 2017, i.e. half a Titan year. The lower part of the stratosphere…
Mesoscale modeling of Venus' bow-shape waves
Maxence Lefèvre, Aymeric Spiga, Sébastien Lebonnois
The Akatsuki instrument LIR measured an unprecedented wave feature at the top of Venusian cloud layer. Stationary bow-shape waves of thousands of kilometers large lasting several E…
Global climate modeling of Saturn's atmosphere. Part II: multi-annual high-resolution dynamical simulations
Aymeric Spiga, Sandrine Guerlet, Ehouarn Millour +9
The Cassini mission unveiled the intense and diverse activity in Saturn's atmosphere: banded jets, waves, vortices, equatorial oscillations. To set the path towards a better unders…
Titan's lakes chemical composition: sources of uncertainties and variability
