Air Quality Monitoring in Tacoma

Air quality affects all community members, however some neighborhoods experience burdens based on proximity to industry, the built environment, or different housing types. The City plans to use data gathered from air quality sensors to prioritize infrastructure funding and program efforts to address climate change – such as mitigating heat islands, assessing impacts of heat and smoke events, and identifying tree planting priorities.  


PurpleAir: Existing Air Quality Monitors

There are currently dozens of PurpleAir sensors installed in the Tacoma area which monitor air quality in real-time. Most of these sensors are owned and operated by private residents and/or organizations, and are not maintained by the City of Tacoma. The data collected using PurpleAir sensors is intended to be educational and non-regulatory, meaning air quality levels reported cannot be used for permitting, compliance, policy, or interpretation of health effects.
