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:

Monitoring Data and Air Quality Monitoring Stations

Below is a list of current air monitoring stations in Spokane County. Select a station to get more information.

Personal Air Sensors for Citizen Scientists, Researchers and Developers

Air sensors are lower-cost, portable devices that can estimate a variety of pollutants including: dust, fine particulate matter, carbon dioxide, carbon monoxide, ozone, nitrogen oxide, and many others. These sensors are available to anyone and  typically cost between $100 and $2,500 – a fraction of the cost of our regulatory air monitors.

Although air sensors are less expensive than a regulatory air monitor, they are also less accurate. The instruments that federal, state and local air quality agencies use to measure air pollutants are built, tested, sited, operated and maintained according to rigorous air monitoring regulations set by the Environmental Protection Agency (EPA). They provide high-quality data.

Air sensors can be very useful and may help answer questions about air quality, such as:

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.
