Photochemical Assessment Monitoring Station
From Wikipedia, the free encyclopedia
Photochemical Assessment Monitoring Stations are ambient air monitoring sites mandated by the 1990 Clean Air Act amendments. Placed in areas of high ozone, they monitor volatile organic compounds, nitrogen oxides, ozone and meteorological parameters. The data is used by the Environmental Protection Agency to understand the causes of ozone pollution and monitor improvement.
