Glittery clouds in exoplanetary atmospheres?

International Journal of Astrobiology, 2009
AbstractCloud formation modelling has entered astrophysics as a new field of research for planetary and brown dwarf atmospheres. Clouds are a chemically and physically very active component of an atmosphere since they determine the remaining gas phase and change the object's albedo depending on their material composition.

Red clouds in reducing atmospheres

Icarus, 1973
A dark reddish-brown high-molecular weight polymer is produced by long wavelength ultraviolet irradiation of abundant gases in reducing planetary atmospheres. The polymer is examined by paper chromatography, mass spectrometry, and infrared, visible, and ultraviolet spectroscopy. High carbon-number straight-chain alkanes with NH2 and, probably, OH and C

Multiple scattering in atmospheric clouds: lidar observations

Applied Optics, 1976
The contribution of multiple scattering in lidar backscattering from clouds has been investigated using a ruby laser at 694 nm. The depolarization of an incident linearly polarized signal is measured with a multichannel lidar receiver. An analysis is presented whereby this information can be utilized to measure the multiple scattering in clouds in ...

Clouds in Planetary Atmospheres

2004
In the terrestrial atmosphere clouds are familiar as vast collections of small water drops or ice cyrstals suspended in the air. The study of clouds touches on many facets of armospheric science. The chemistry of clouds is tied to the chemistry of the surrounding atmosphere.

Interstellar Cloud Material: Contribution to Planetary Atmospheres

Science, 1978
A statistical analysis of the properties of dense interstellar clouds indicates that the solar system has encountered at least a dozen clouds of sufficient density to cause planets to accumulate nonnegligible amounts of some isotopes. The effect is most pronounced for neon. This mechanism could be responsible for much of the neon in Earth's atmosphere.

Engineering cloud nine [atmospheric instruments]

IEEE Spectrum, 2003
This article describes the career of Tommy Thompson who builds instruments that let atmospheric scientists dissect the weather. His early interest in building crystal radio sets and telephone systems is described. His current work on the cloud research program in Florida is also described.

Infrared Signatures from Atmospheric Clouds

1980
Abstract : Clouds are an important source of variations in the IR background radiation was detected by satellite surveillance systems, because clouds absorb and scatter solar radiation and have a blackbody temperature different from that of the earth's surface.
