Air Quality Monitoring

Measuring the ambient air is done using a network of monitoring stations located throughout Spokane County. We monitor for the criteria air pollutants that are most prevalent in Spokane's airshed, which includes ozone, fine particles (PM2.5) and coarse particles (PM10). Ozone is only monitored during ozone season (May - September).

Monitoring air quality and weather patterns enables us to:

• Forecast daily air quality conditions and significant events
• Report current air quality in our communities
• Issue burn bans on indoor wood heating and outdoor burning
• Help people use data to make clean air choices
   

Monitoring Data

• Current air quality levels are reported on the agency's "Current Air Quality" web page.
• Monthly summaries of air quality data are found here: Monthly summaries.
