Stability of the Martian Atmosphere [PDF]
Science, 1972 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.

What Is the Radiation Impact of Extreme Solar Energetic Particle Events on Mars?
Space Weather, 2023 Solar Energetic Particles (SEP) are one of the major sources of the Martian radiation environment. It is important to understand the SEP‐induced Martian radiation environment for future human habitats on Mars.

Thermospheric density responses to Martian dust storm in autumn based on MAVEN data
Geodesy and Geodynamics, 2022 The unique seasonal surface dust storms on Mars have a significant impact on the Martian atmosphere. However, due to the lack of observations, semi-empirical models are difficult to simulate the density changes in the thermosphere with the existence of ...

Mie scattering and the Martian atmosphere [PDF]
Symposium - International Astronomical Union, 1971 It has been suggested that the discrepancy between radio occultation determinations of the Martian atmospheric surface pressure (3.8 to 7 mb) and those deduced from optical polarization measurements and a simple Rayleigh atmosphere model (about 10 mb) are the results of sub-micron sized aerosols in the Martian atmosphere.

The Planetary Science Journal, 2023 The isotopic signature of atmospheric carbon offers a unique tracer for the history of the Martian atmosphere and the origin of organic matter on Mars. The photolysis of CO _2 is known to induce strong isotopic fractionation of the carbon between CO _2 ...

THE MARTIAN ATMOSPHERIC BOUNDARY LAYER [PDF]
Reviews of Geophysics, 2011 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.

Clouds in the Martian Atmosphere [PDF]
, 2021 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,

Optimal Technology Allocation of in the Life Support Subsystem with Maximum Reliability [PDF]
فناوری در مهندسی هوافضا, 2023 The atmosphere of the Red Planet or Mars contains 95% of carbon dioxide, 3% of nitrogen, 1.6% of argon and only a small amount of oxygen, and in terms of concentration is about one percent of the planet's atmosphere, which makes it virtually impossible ...
