Air Quality Monitoring Data

Air quality monitoring networks operate in urban and rural areas throughout Arizona so citizens may know local air quality conditions and to help ADEQ and local air quality control districts identify the causes of air pollution. The networks are composed of individual monitoring sites that collect ambient air quality data in a variety of representative settings. These data help determine air pollution sources and allow scientists to assess the effects of pollution on public health and welfare effects. The networks also monitor the nature and causes of visibility impairment.

Numerous agencies, companies, individuals and organizations collect the ambient air quality monitoring data, which ADEQ annually publishes in a report on the state's air quality conditions.
