Ambient Air Monitoring
The Air Monitoring Section operates a statewide network of ambient (outdoor) air pollution monitors. These monitors serve three primary functions:
- To determine compliance with the Clean Air Act’s pollution standards
- To inform the public on the state of Oklahoma’s air quality
- To monitor areas of special or immediate concern
National Ambient Air Quality Standards (NAAQS)
NAAQS Table and Current Highs - a list of each standard and highest monitored values for the current year. These standards define the maximum permissible concentrations for common air pollutants, or criteria pollutants.

Informing the Public
Our primary methods of informing the public are:
- AQI (Air Quality Index), Ozone & PM Alerts, Health Advisories
- Current Air Quality & AQI Forecasts
