Dissipation of Planetary Atmospheres

Science, 1959
Escape-level density is approximately inversely proportional to gravity and with decreasing mass will tend toward that of interplanetary gas. When this value is reached, dissipation must cease. The minimum possible ground density of lunar air is calculated to be 10 –12 that of the air at normal temperature and ...

Planetary atmospheres

Reviews of Geophysics, 1983
The period from 1979 to 1982 has been characterized by extensive exploration of the Solar System. Pioneer and Voyager missions to Venus, Jupiter, and Saturn combined with ongoing analysis and data collection from the Viking‐Mars mission have contributed greatly to our understanding of planetary atmospheres.The Pioneer orbiter and the Pioneer multiprobe

Planetary atmospheres

Reviews of Geophysics, 1975
The past 4 years have been marked by tremendous observational advances in the field of planetary atmospheres. A great deal of new information has been obtained by unmanned spacecraft, notably the Mariner 9 mission to Mars, the Pioneer 10 mission to Jupiter, and the Mariner 10 mission to Venus, all sponsored by the National Aeronautics and Space ...

H3+ cooling in planetary atmospheres

Faraday Discussions, 2010
We review the role of H3+ in planetary atmospheres, with a particular emphasis on its effect in cooling and stabilising, an effect that has been termed the "H3+ thermostat" (see Miller et al., Philos. Trans. R. Soc. London, Ser. A, 2000, 58, 2485).

Planetary atmospheres

2021
The emphasis of this book is on comparative aspects of planetary atmospheres, generally meaning comparison with the Earth, including atmospheric composition, thermal structure, cloud properties, dynamics, weather and climate, and aeronomy. The goal is to look for common processes at work under different boundary conditions in order to reach a ...
