Photochemistry and stability of the atmosphere of Mars

Advances in Space Research, 1995
An understanding of the composition, structure, transport and photochemical processes of the present atmosphere of Mars is essential for addressing such fundamental questions as the stability, evolution and the origin of the Martian atmosphere. This paper discusses our current knowledge of the photochemistry and stability of the Martian atmosphere ...

Stability of an oxygen atmosphere on ganymede

Icarus, 1977
Photolysis of water and subsequent escape of hydrogen can give rise to an oxygen atmosphere on Ganymede. Growth of the atmosphere may be limited by escape of fast oxygen atoms formed by photodissociation of O_2. Escape of oxygen and hydrogen in an equilibrium configuration should balance net evaporation of water from the satellite's surface and the ...

The stability of benzene in planetary atmospheres

2022
<p>Benzene is the simplest organic compound with a 6-carbon aromatic ring. As such, it was used as a first order representative of aromatic compounds in planetary atmospheres. These compounds can be brought by asteroid impacts into rocky planetary atmospheres, where they can serve as precursors for further synthesis.

Spectral Measurements and Atmospheric Stability

Journal of the Atmospheric Sciences, 1969
Abstract The influence of atmospheric stability on the vertical spectra of refractive index and air velocity is studied. Spectra of refractive index and air velocity are deduced from beam-swinging experiments in the area between Norway and Denmark where a height interval from some 400 m to some 12 km is involved.

The stability of an SO2 atmosphere on Io

Nature, 1979
Active volcanism observed on Io could provide a continuous source of gases from Io's interior. Only a small fraction of what is coming out of Io's volcanoes is escaping; the bulk of it is being recycled. There must be an atmospheric reservoir which maintains the gases until they have had a chance to recycle.

Atmospheric Thermodynamics and Vertical Stability

1980
From the thermodynamical point of view, a system is any body of a given mass and composition under study. All the rest of the bodies with which the system may eventually interact are called its surroundings.

The History and Stability of Atmospheric Oxygen

Science, 1971
There are three processes weakly concentration-dependent that keep changes in concentration of atmospheric pressure from being a random walk—inhibition of net photosynthesis by oxygen, the passage of hydrogen through the oxidizing part of the atmosphere before it escapes from the earth, and burial of reduced carbon in anaerobic water.

The Stabilization of CO2 Level in the Atmosphere

SAE Technical Paper Series, 1992
<div class="htmlview paragraph">Twenty strategies to stabilize atmospheric CO₂ level are examined. Controlling the rate of CO₂ emissions first, by modest conservation and increased use of methane, is feasible; it costs little and provides a stable base for other action.

Chemical stability of the atmosphere and ocean

Palaeogeography, Palaeoclimatology, Palaeoecology, 1989
Abstract The Earth system processes most of the chemical components of its atmosphere and oceans in geologically short periods of time. It does this in a regulated way, one that maintains a remarkably constant surface environment. This we know primarily from the fossil record of uninterrupted, complex life on Earth that extends over the last billion ...
