The results show just what fraction of the radiation reaches a planet's surface, as a function of the intensity and energy of the source and the thickness of the planetary atmosphere
Ionospheres act as a boundary between planetary atmospheres
and space, containing weakly ionized plasmas that are strongly coupled to their neutral atmospheres, but also influenced by the conditions in the space environment.
Current instruments are incapable of providing the kind of information necessary to study planetary atmospheres
By blocking the light of the host star, the Coronagraph Instrument will enable detailed measurements of the chemical makeup of planetary atmospheres
We think this huge thunderstorm is driving these cloud particles upward, sort of like a volcano bringing up material from the depths and making it visible from outside the atmosphere," explains Sromovsky, a senior scientist at UW-Madison and an expert on planetary atmospheres
Clouds often play key roles in planetary atmospheres
Accurate descriptions of planetary atmospheres
might also help shed light on how the evolution of the solar system left the outer planets with a high percentage of volatiles, but not the inner planets.
IN SEPTEMBER I attended ExoClimes 2010, at the University of Exeter, a workshop about the diversity of planetary atmospheres
within our solar system and beyond.
