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 and Air Quality Monitoring Stations
- 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.
Below is a list of current air monitoring stations in Spokane County. Select a station to get more information.
- Augusta Avenue & Fiske Street, measures fine particles (PM2.5) and coarse particles (PM10)
- Broadway Avenue near University, measures PM2.5
- Colbert, measures PM2.5
- Greenbluff, Ecology operated site, measures ozone (O3) during ozone season (May-Sept)
- Monroe Street & Wellesley Avenue, Ecology-operated site, measures PM2.5
- Turnbull National Wildlife Refuge, measures O3 (May-Sept) and PM
Personal Air Sensors for Citizen Scientists, Researchers and Developers
Air sensors are lower-cost, portable devices that measure the quality of the air we breathe. These sensors are available to anyone and typically cost between $100 and $2,500 – a fraction of the cost of our regulatory air monitors.
Air sensors can estimate a variety of pollutants including: dust, fine particulate matter, carbon dioxide, carbon monoxide, ozone, nitrogen oxide, and many others.
Although air sensors are less expensive than a regulatory air monitor, they are also less accurate. The monitors that report to our website are built and operated according to rigorous air monitoring regulations determined by the Environmental Protection Agency (EPA), and they provide high-quality data.
But air sensors can be very useful and may help answer questions about air quality, such as:
- How does the air quality during my commute compare to my air quality at home?
- How does air quality near my home compare to other neighborhoods and areas?
- Is air quality in my neighborhood better during the summer or winter? Day or night?
The U.S. EPA has a website that provides information for citizen scientists and others on how to select and use low-cost, portable air sensor technology and understand results from monitoring activities. The information can help the public learn more about air quality in their communities.
