Portland - SW Kelly Ave & SW Curry St Air Monitoring Station | Oregon DEQ

Portland - SW Kelly Ave & SW Curry St is an air monitoring station located at 330 SW Curry St in Portland, Multnomah County, Oregon. Operated by the Oregon Department of Environmental Quality, this station is part of the broader US EPA Air Quality System (AQS) network, which monitors criteria pollutants and other atmospheric parameters across the United States. The station operates under the regulatory framework of the Clean Air Act and EPA ambient air quality standards. While specific parameters measured are not detailed, typical urban monitoring stations in Oregon track pollutants such as ozone, particulate matter (PM2.5 and PM10), nitrogen dioxide, sulfur dioxide, carbon monoxide, and lead. The station's location in a mixed residential-commercial area provides representative data for Portland's urban air quality. This monitoring station supports public health by providing data used for air quality index (AQI) reporting and regulatory compliance. Its continuous operation helps track long-term trends and informs local air quality management decisions. The station is part of Oregon's network that ensures the state meets National Ambient Air Quality Standards (NAAQS).

Portland's air quality is influenced by urban emissions, including vehicle traffic, industrial activities, and wood smoke from residential heating. The station's location near a major intersection provides data on near-roadway pollution exposure. Monitoring in this area helps assess compliance with EPA standards and supports public health advisories during wildfire events, which increasingly affect the Pacific Northwest.
