Overview
Portland - Lincoln High School (PLH) is an operational air monitoring station in Portland, Oregon, operated by the Oregon Department of Environmental Quality. It contributes to the US EPA Air Quality System (AQS) network.
Portland - Lincoln High School (PLH) is an air monitoring station located at 1600 SW Salmon Street in Portland, Multnomah County, Oregon. Operated by the Oregon Department of Environmental Quality, it is part of the broader US EPA Air Quality System (AQS) network, which monitors criteria pollutants and other atmospheric parameters across the United States. As an air monitoring station, PLH typically measures pollutants such as ozone, particulate matter (PM2.5 and PM10), nitrogen dioxide, sulfur dioxide, carbon monoxide, and lead, in accordance with National Ambient Air Quality Standards (NAAQS). The station may also track meteorological parameters like wind speed and direction, temperature, and humidity to support air quality modeling and forecasting. The station serves the Portland metropolitan area, providing critical data for public health advisories, regulatory compliance, and research on urban air pollution. Its location at a high school allows for community-relevant monitoring, supporting local environmental awareness and policy decisions. The data collected helps assess long-term trends and the effectiveness of emission reduction strategies.
Environmental context
Portland's air quality is influenced by a mix of urban emissions, including transportation, industrial activities, and residential heating. The city's location in the Willamette Valley can lead to temperature inversions that trap pollutants. Monitoring stations like PLH are essential for tracking compliance with NAAQS and identifying pollution hotspots. The Oregon Department of Environmental Quality uses data from this station to inform air quality alerts and develop strategies to reduce exposure to harmful pollutants.
