Arctic Haze and Air Pollution
Arctic haze is the phenomenon of large-scale industrial air pollution found all through the arctic air mass. Vertical profiles of air concentrations, obtained during several aircraft measurement programs in the Arctic, have offered the following explanation of arctic haze origin. Very long range, ep...

Arctic haze is the phenomenon of large-scale industrial air pollution found all through the arctic air mass. Vertical profiles of air concentrations, obtained during several aircraft measurement programs in the Arctic, have offered the following explanation of arctic haze origin.

Polluted air masses, carrying a mixture of anthropogenic and natural pollutants from a variety of sources in different geographical areas have been identified in the arctic atmosphere at altitudes from 2 to 4 or 5 km. The layers of polluted air at altitudes below 2.5 km can be traced to episodic transport of air masses from anthropogenic sources situated closer to the Arctic.
