Overview
Joanna Bald is an air monitoring station in Graham County, North Carolina, operated by the North Carolina Dept of Environmental Quality. It provides ambient air quality data as part of the state's monitoring network.
Joanna Bald is an air monitoring station located in the remote forested area of Graham County, North Carolina, along Forest Road 423 Spur. It is operated by the North Carolina Department of Environmental Quality and contributes to the state's ambient air quality monitoring network. The station is part of a broader effort to track criteria pollutants and support compliance with the US EPA's National Ambient Air Quality Standards (NAAQS). The station operates under the regulatory framework of the US EPA's Air Quality System (AQS), which standardizes data collection and reporting across the country. While specific parameters measured at this site are not detailed, typical rural monitoring stations in North Carolina measure ozone, particulate matter (PM2.5 and PM10), and meteorological variables. The station's remote siting helps characterize background air quality and long-range transport of pollutants. Environmental monitoring at Joanna Bald supports understanding of air quality in the Appalachian region, which can be influenced by both local sources and regional transport. Data from this station aids in assessing compliance with health-based standards and informs public health advisories. The station's continued operation ensures long-term trend analysis for this ecologically sensitive area.
Environmental context
The Joanna Bald station is situated in a rural, forested area of the Appalachian Mountains, providing baseline air quality data away from major urban or industrial sources. This siting is valuable for understanding regional background pollution levels and the influence of transported emissions. The station's data contributes to the EPA's AQS network, supporting assessments of ozone and particulate matter trends in the southeastern United States.
