haze - an atmospheric condition marked by a slight reduction in atmospheric visibility, resulting from the formation of photochemical smog, radiation of heat from the ground surface on hot days, or the development of a thin mist.
Haze - An atmospheric aerosol of sufficient concentration to be visible. The particles are so small that they cannot be seen individually but are still effective in visual range restriction.
Haze (Hazy): A phenomenon that results in reduced visibility due to the scattering of light caused by aerosols. Haze is caused in large part by man-made air pollutants.
Regional Haze - The haze produced by a multitude of sources and activities, which emit fine particles and their precursors across a broad geographic area. The U.S.

Coefficient of Haze (COH)- A measurement of visibility interference in the atmosphere.
Cogeneration- The consecutive generation of useful thermal and electric energy from the same fuel source.
Arctic haze A persistent winter diffuse layer in the Arctic atmosphere whose origin may be related to long-range transport of midlatitude continental man-made pollutants.
Coefficient of Haze (COH) - a measurement of the quantity of dust and smoke in the atmosphere in a theoretical 1000 linear feet of air. A COH of less than 1 is considered clean air and more than 3 is considered dirty air ...
The brown haze sometimes seen over cities is mainly nitrogen oxides. These gases are also partly responsible for the generation of ozone, which is produced when nitrogen oxides react with other chemicals in the presence of sunlight.
Smog (photochemical smog): Literally a contraction of "smoke" and "fog"; the colloquial term used for photochemical fog, which includes ozone and numerous other contaminants. Smog is usually adds a brownish haze to the atmosphere.
Air pollution can threaten the well-being of humans, trees, lakes, crops, and animals, as well as damage the ozone layer and buildings. Air pollution also can cause haze, reducing visibility in national parks and wilderness areas.
