The Air Quality Monitoring Section ensures the ambient air quality in Wyoming is maintained in accordance with the National Ambient Air Quality Standards. To carry out this goal, we operate and maintain a network of ambient air quality monitors and require industrial pollution sources to conduct source specific ambient air monitoring.
All ambient air quality data collected by the AQD is loaded into the U.S. Environmental Protection Agency’s Air Quality System database. Data is typically available within 90 days of the end of each calendar year’s quarter.
Gaseous Pollutant and Scenic Monitoring
Gaseous pollutant, meteorological, and scenic monitoring information can be viewed on the Wyoming Air Quality Monitoring Network. Quarterly and annual monitoring station reports can be accessed via the AQD’s Open Air Web Resource. Visitors to WyVisNet can access daily summary graphs of station data from the Historical Data Concentration located at the bottom of the webpage for each monitoring station. Validated data can be requested by submitting a records request.
