Planetary Atmospheres

2015
The essentials of planetary atmospheres of the solar system are concisely reviewed, including their thermodynamics, radiation, chemistry, and dynamics. First, the diversity of atmospheric composition and basic physical properties is described, including the vertical structure.

Planetary Atmospheres and Aurorae

1987
The observation of planetary atmospheres in the ultraviolet range provides specific advantages. A number of strong emissions from atoms and diatomic molecules appear in this spectral region; also a number of molecules have both continuumlike and narrow-band absorptions.

The composition of planetary atmospheres

Journal of Quantitative Spectroscopy and Radiative Transfer, 1971
Abstract The present status of research on the composition of planetary atmospheres is reviewed. It is shown that CO 2 is the major constituent in the atmospheres of Venus and Mars, and that H 2 is almost certainly the dominant constituent for the outer planets Jupiter, Saturn, Uranus, and Neptune. Ground based i.r.

The Photochemistry of Planetary Atmospheres

1988
Recent theoretical and observational investigations of photochemical processes in the atmospheres of the planets and their satellites are reviewed. Particular attention is given to the CO2-dominated atmospheres of Mars and Venus, the hydrogen-dominated atmospheres of the Jovian planets, the SO2 atmosphere of Io, and the massive atmospheres of Titan and

Isotopic ratios in planetary atmospheres

Advances in Space Research, 1995
Recent progress on measurements of isotopic ratios in planetary or satellite atmospheres include measurements of the D/H ratio in the methane of Uranus, Neptune and Titan and in the water of Mars and Venus. Implications of these measurements on our understanding of the formation and evolution of the planets and satellite are discussed.

Planetary Atmospheric Microprobes

1999
ABSTRACT Microprobes can be used as research tools allowing dedicated measurements in regions near planets or moons usually not accessible for orbiting spacecraft. Here, we mainly discuss the investigation of the near environment of Jupiter's Galilean moon lo.

Ultraviolet Measurements in Planetary Atmospheres

Applied Optics, 1967
The impact of the latest optical and electronic component developments on far uv rocket spectrophotometry is discussed. Results of some recent experiments studying earth airglow and aurorae are reviewed. It is shown that weaker spectral features can he measured in the region 1100 A to 3000 A than at any longer wavelength.

Escape of Planetary Atmospheres

2012
The extreme radiation and plasma environments during the period of the young active Sun/Stars have important implications for the evolution of planetary atmospheres and may be responsible that planets with a low gravity like early Mars most likely could never build up a dense atmosphere during the first few 100 Myr after their origin. On the other hand
