UPWIND MONITOR FROM DOMINANT WIND DIRECTION - Air Monitoring Station in Bristol, Tennessee

UPWIND MONITOR FROM DOMINANT WIND DIRECTION is an air monitoring station located at 364 Exide Dr. in Bristol, Sullivan County, Tennessee, United States. The station is operational and serves as part of the local air quality monitoring network, focusing on upwind conditions relative to the dominant wind direction. The facility operates under the regulatory framework of the U.S. EPA Air Quality System (AQS), which sets standards for criteria pollutants such as ozone, particulate matter, carbon monoxide, sulfur dioxide, and nitrogen dioxide. As an upwind monitor, it helps establish background pollutant levels, which are essential for assessing the impact of local emission sources. The station is reported by Exide Corporation, indicating industrial oversight. This monitoring station plays a key role in understanding air quality dynamics in the Bristol area, particularly in relation to industrial activities. Its data supports compliance with National Ambient Air Quality Standards (NAAQS) and informs public health advisories. The station contributes to the broader Tennessee air monitoring network, aiding in regional environmental management.

The Bristol area is situated in the Appalachian region, where topography can influence pollutant dispersion. The upwind monitor provides baseline data crucial for distinguishing between local and transported pollution. Parameter coverage typically includes criteria pollutants, though speciation may be limited. Siting representativeness is important for capturing regional background levels, and reporting continuity through the AQS ensures data comparability.
