The time period between 280-345 Myr BP of Earth's geologic history. Characterized by glacial onsets and melting and massive migration and extinctions of species during this period.

The relationship between wavelength and temperature in relation to blackbody radiation. The wavelength decreases as the temperature increases. The common formula to determine this relationship is Plank's Formula.
Industry:Chemistry; Weather
The wavelengths of light absorbed by ozone in the visible region, approximately 380 to 750 nm. Compare to ozone's ultraviolet absorption region, the Hartley-Huggins band.

This type of transport involves air pollutants in the atmosphere. If the pollutants are light enough---such as gases or low density particles---or are propelled high enough in the atmosphere, they may be picked up in horizontal winds and transported long distances. If the air pollutants travel within the moving air mass greater than 100 kilometers, than this is considered long range transport. In the spring of 2011, after the nuclear accident following the March 2011 9. 0 magnitude earthquake off the Japanese coast, radioactive particles released from the Tokyo Electric Power nuclear reactor complex in the Fukushima Prefecture, Japan were detected on the east coast of the United States at levels that were slightly above background.

This is defined as the way heat from the sun is absorbed, scattered, returned, or deposited around the earth and can be expressed as some radiation arrival rate per the unit of area of the surface. The radiation flux can be the total amount of radiation that the earth collects, emits, and disperses.

This manmade VOC is highly reactive in the atmosphere. It is a gas at room temperature and when released, it readily reacts with oxidizing agents, most quickly with hydroxyl radical, half life.

This compound, also called perchloroethylene, is used for dry cleaning purposes; often it is recycled by the cleaners for reuse.

Water present in the atmosphere in gaseous form; the source of all forms of condensation and precipitation. Water vapor, clouds, and carbon dioxide are the main atmospheric components in the exchange of terrestrial radiation in the troposphere, serving as a regulator of planetary temperatures via the greenhouse effect. Approximately 50 percent of the atmosphere's moisture lies within about 1. 84 km of the earth's surface, and only a minute fraction of the total occurs above the tropopause.

Those atmospheric components that absorb strongly in the infrared region of the spectrum. Infrared radiation is reflected and emitted by the earth's surface as heat and causes a fairly large warming effect when trapped by these gases in the atmosphere. In order of abundance and importance as greenhouse gases are water vapor, carbon dioxide, ozone, nitrous oxide, methane, and chlorofluorocarbons (CFCs). Absorption by water vapor, the most common greenhouse gas, explains why many humid or cloudy days feel much hotter than dry, clear days of the same air temperature. Because of these gases, only about 5% of the radiation escapes from the atmosphere while more than 90% is radiated back to the surface of the earth.
Industry:Chemistry; Weather
The scientific study of the relationships and interactions of the substances in the gases around the earth. Examples would be determination of the concentrations, sources, and sinks of ozone in the troposphere and stratosphere and the greenhouse gases that surround earth. This includes all reactions of and sources and sinks on the surface of the earth of particles released in the air.
