Stability of the Martian Atmosphere [PDF]
A detailed chemical dynamic model is presented for a moist martian atmosphere. Recombination of carbon dioxide is catalyzed by trace amounts of water. The abundances of carbon monoxide and molecular oxygen should vary in response to changes in atmospheric water and atmospheric mixing.

Clouds in the Martian Atmosphere [PDF]
Although resembling an extremely dry desert, planet Mars hosts clouds in its atmosphere. Every day somewhere on the planet a part of the tiny amount of water vapor held by the atmosphere can condense as ice crystals to form mainly cirrus-type clouds. The existence of water ice clouds has been known for a long time and they have been studied for decades,

A mesoscale model for the Martian atmosphere [PDF]
The Pennsylvania State University/National Center for Atmosphere Research Mesoscale Model Version 5 (MM5) has been converted for use on Mars. Modifications are based on schemes implemented in the Geophysical Fluid Dynamics Laboratory Mars General Circulation Model (GCM).

Impact sculpting of the early martian atmosphere. [PDF]
Intense bombardment of solar system planets in the immediate aftermath of protoplanetary disk dissipation has played a key role in their atmospheric evolution. During this epoch, energetic collisions will have removed substantial masses of gas from rocky planet atmospheres.

Observation of pressure variations in the Martian atmosphere [PDF]
Pressure waves in the Martian atmosphere could so far be observed only in the presence of clouds. Thanks to the Mars Global Surveyor/Mars Orbiter Laser Altimeter (MGS/MOLA), a direct observation is now possible, with the method presented here. Many more events are thus potentially observable. We compare altimetry measurements from MGS/MOLA and spectral

THE MARTIAN ATMOSPHERIC BOUNDARY LAYER [PDF]
The planetary boundary layer (PBL) represents the part of the atmosphere that is strongly influenced by the presence of the underlying surface and mediates the key interactions between the atmosphere and the surface. On Mars, this represents the lowest 10 km of the atmosphere during the daytime.

The value of returning a sample of the Martian atmosphere. [PDF]
The elemental and isotopic abundances of major species in the Martian atmosphere have been determined, but analyses often lack sufficient precision, and those of minor and trace species are frequently not well known. Many important questions about the evolution and current state of Mars require the kind of knowledge that can be gained from analysis of ...
