Origin and role of water ice clouds in the Martian water cycle as inferred from a general circulation model

In this paper, we present the results obtained by the general circulation model developed at the Laboratoire de Meteorologie Dynamique which has been used to simulate the Martian hydrological cycle.…

The Mars Atmosphere and Volatile Evolution (MAVEN) Mission

The MAVEN spacecraft launched in November 2013, arrived at Mars in September 2014, and completed commissioning and began its one-Earth-year primary science mission in November 2014. The orbiter’s…

Recent formation and evolution of northern Martian polar layered deposits as inferred from a Global Climate Model

[1] We present a time-marching model which simulates the exchange of water ice between the Martian northern cap, the tropics, and a high-latitude surface reservoir. Net annual exchange rates of water…

Recent ice-rich deposits formed at high latitudes on Mars by sublimation of unstable equatorial ice during low obliquity

Using the ice accumulation rates estimated from global climate model simulations, it is shown that, over the past ten million years, large variations of Mars' obliquity have allowed the formation of such metres-thick, sedimentary layered deposits in high latitude and polar regions.

Density and temperatures of the upper Martian atmosphere measured by stellar occultations with Mars Express SPICAM

[1] We present 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…

Formation of Glaciers on Mars by Atmospheric Precipitation at High Obliquity

High-resolution climate simulations performed with a model designed to simulate the present-day Mars water cycle but assuming a 45° obliquity points to an atmospheric origin for the ice and reveals how precipitation could have formed glaciers on Mars.

The Latitudinal Distribution of Clouds on Titan

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.

Three-dimensional modeling of ozone on Mars

We present the first three-dimensional model simulations of ozone on Mars. The model couples a state-of-the-art gas-phase photochemical package to the general circulation model developed at…

Hyperspectral imaging of convective CO2 ice clouds in the equatorial mesosphere of Mars

[1] A unique feature of the Martian climate is the possibility for carbon dioxide, the main atmospheric constituent, to condense as ice. CO2 ice is usually detected as frost but is also known to…

Observations of the south seasonal cap of Mars during recession in 2004–2006 by the OMEGA visible/near‐infrared imaging spectrometer on board Mars Express

[1] The OMEGA visible/near-infrared imaging spectrometer on board Mars Express has observed the southern seasonal cap in late 2004 and 2005 and then in the summer of 2006. These observations extended…
