The National Wildfire Coordinating Group’s Smoke Committee with assistance from The Nature Conservancy, held a webinar focused on the emerging world of low-cost air quality sensors. Air quality sensors are a rapidly expanding segment of the air pollutant monitoring world. There are now low-cost and easily deployable air quality monitors becoming readily available to individuals and communities to better understand the state of their air quality. New technological advances are transforming and revolutionizing the understanding of air quality. These sensors are changing the way air quality is measured and reported around the world. Low-cost and portable air quality sensors are now in the hands of citizens who want to investigate air quality in their neighborhoods and communities. They are a method to monitor nearby sources of air pollutants, including roadways, rail yards, ports, industry and perhaps wildland fire smoke impacts. These sensors are quickly becoming extensive community networks with data available on-line and used by air quality regulatory agencies to understand the movement and extent of air pollution impacts. Although these sensors are not up to the standard of EPA Federal Reference Method or Federal Equivalence Method monitors, they are providing rapid air quality information that can play a role in understanding and avoiding high pollution periods which is beneficial to reducing public exposure and protecting health. These new monitoring tools are also helping assist air quality managers with implementing the nation’s air quality standards.
