総称して、すべての炭化の水素メタン以外。メタンは、雰囲気の中でかなり長命は、大規模な比較的一定の混合比、対流圏で。他の炭化水素 30–30 000 回メタン、従って大いにより大きい可変性を示すより短い有効期間要因、ソースでローカライズされたより傾向があります。以来、このようなソースは、しばしば自然の中で人為的、Nmhc 濃度は気団の汚染度の指標としてよく使用されます。

Colorless, inflammable gas of formula CH<sub>4</sub>; the simplest hydrocarbon. Methane enters the atmosphere as a result of the anaerobic decay of organic matter in, for example, swamps and rice paddies, and is also produced in large quantities by cattle and termites. It is formed along with coal and oil in fossil fuel deposits, and released to the atmosphere on mining. Methane is itself burned as a fuel, being the major constituent of natural gas. The atmospheric mixing ratio of methane is currently about 1. 7 parts per million and has been rising gradually since the industrial era began. The atmospheric lifetime of methane is about eight years. As well as influencing the chemistry of the atmosphere, methane is a strong greenhouse gas and an important source of stratospheric water vapor, and it contributes to global warming.
Industry:Weather
A part of meteorology that deals with observations and processes in the smallest scales of time and space, approximately smaller than 1 km and less than a day (i. E. , local processes). Micrometeorological processes are limited to shallow layers of frictional influence (slightly larger-scale phenomena like convective thermals are not part of micrometeorology). Therefore, the subject of micrometeorology is the bottom of the atmospheric boundary layer; namely, the surface layer. Exchange processes of energy, gases, etc. , between the atmosphere and the surface (water, land, plants) are important topics. Therefore, micrometeorology is closely connected with most of the human activities in the atmosphere. Microclimatology describes time averaged (long- term) micrometeorological processes, and micrometeorologists are interested in their fluctuations. Compare mesometeorology, macrometeorology.
