The data contained in this layer file are representative of the current EGLE statewide air monitoring database. This monitoring network meets the United States Environmental Protection Agency's (USEPA) monitoring regulations. The layer contains location, site photographs, and defines the specific pollutants monitored for at that site. Overall the air monitoring network collects data for the six criteria pollutants outlined through the USEPA's National Ambient Air Quality Standards (i.e., carbon monoxide, lead, nitrogen dioxide, ozone, particulate pollution, and sulfur dioxide) along with several other pollutants, as relevant to each area.
