Air Monitoring

The ambient air monitoring network is a key element in making sure the air we breathe in our communities is healthy and if we are in attainment with the National Ambient Air Quality Standards (NAAQS). Michigan’s network has over 40 locations across the state with over 100 air monitors.

The air quality monitoring network

The purpose of the monitors it to measure pollutant concentrations in the outdoor (ambient) air. Ambient air is the air that the public breathes where we live, work, and play. The purpose of the network is to measure air pollutants over long periods to:

  • ensure air quality standards are met,
  • identify pollution trends,
  • support air pollution forecasting,
  • provide real-time air quality information,
  • assess community exposure, and
  • be used in air quality models.

This network consists of meteorological, gaseous, particle and air toxics monitors mandated by the USEPA in 40 CFR, Part 58 as part of the Michigan State Implementation Plan (SIP). The network is not intended to tell us where pollutants come from or to be used as a tool to regulate a specific company or industry type.
