Current Ozone Data

The AQD Monitoring Section helps ensure the ambient air quality in the State of Wyoming is maintained in accordance with the National Ambient Air Quality Standards (NAAQS). To carry out this goal, AQD operates and maintains a network of ambient air quality monitors to determine compliance with the NAAQS. 

When areas, like the Upper Green River Basin, are not meeting the NAAQS, AQD also performs special monitoring studies such as the Upper Green Winter Ozone Study (UGWOS) to better understand ozone formation. 

AQD also participates in EPA's national program to inform the public of the current air quality index called AirNow.
