Air Quality in a Subarctic Community

ABSTRACT. Expanding population centred around Fairbanks has brought concern that air pollution in the area may become intolerable. The atmosphere of the lower Chena River Valley is extremely stable during much of the year. Temperature inversions are believed to be among the steepest in the world. In...
