Ambient Air Monitoring

The Air Monitoring Section operates a statewide network of ambient (outdoor) air pollution monitors. These monitors serve three primary functions:

  1. To determine compliance with the Clean Air Act’s pollution standards
  2. To inform the public on the state of Oklahoma’s air quality
  3. To monitor areas of special or immediate concern
