Portland - SE 13th Ave & SE Carlton St Air Monitoring Station, Oregon

Portland - SE 13th Ave & SE Carlton St is an operational air monitoring station located at 6139 SE 13th Street 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 provides standardized air quality data across the United States. As an air monitoring station, it typically measures criteria pollutants such as ozone, particulate matter (PM2.5 and PM10), carbon monoxide, sulfur dioxide, and nitrogen dioxide, in accordance with the National Ambient Air Quality Standards (NAAQS). The station's siting follows EPA guidelines to ensure representativeness of local air quality, often placed in urban or suburban settings to capture population exposure. The station contributes to Oregon's air quality management efforts, supporting regulatory compliance and public health advisories. Data from this station helps track trends, inform emission reduction strategies, and provide communities with real-time air quality information through platforms like AirNow.

Portland's air quality is influenced by a mix of urban emissions, including vehicle traffic, industrial activities, and wood smoke from residential heating. The region's geography, with the Columbia River Gorge channeling winds, can affect pollutant dispersion. Monitoring stations like this one are critical for tracking compliance with NAAQS and identifying pollution episodes, such as during wildfire seasons when particulate matter levels can spike.
