Overview
Starkey is an IMPROVE air monitoring station in Union County, Oregon, operated by the National Park Service. It tracks visibility and particulate matter to support regional air quality assessments.
Starkey is an air monitoring station located in Union County, Oregon, within the United States. It is part of the Interagency Monitoring of Protected Visual Environments (IMPROVE) network, a collaborative program focused on measuring visibility and fine particulate matter in areas of scenic and ecological importance. The station operates under the oversight of the National Park Service, contributing to long-term atmospheric monitoring in the Pacific Northwest. The station's technical scope aligns with the IMPROVE network's standard protocols, which include sampling for PM2.5, light extinction, and aerosol speciation. These measurements support compliance with the US EPA's Air Quality System (AQS) framework and the Regional Haze Rule, which mandates visibility improvement in federal Class I areas. The station's rural siting in northeastern Oregon provides representative data for regional background conditions, away from major urban emission sources. Environmental monitoring at Starkey plays a key role in understanding air quality trends in the Blue Mountain ecoregion. Data from this station help assess the impact of wildfires, agricultural activities, and long-range transport of pollutants on visibility and public health. The station's continuous operation since its establishment ensures a valuable long-term record for atmospheric science and regulatory decision-making.
Environmental context
The Starkey station operates in a rural setting within the Blue Mountain region of northeastern Oregon, an area characterized by mixed conifer forests, grasslands, and agricultural lands. The IMPROVE network's focus on visibility and fine particulate matter is particularly relevant here, as the region experiences seasonal wildfire smoke and occasional dust events. The station's data contribute to understanding regional haze patterns and support the EPA's Regional Haze Rule, which aims to restore natural visibility conditions in protected areas. Siting representativeness is a key consideration, with the station placed to capture background conditions rather than local source impacts.
