AJ Air Monitoring Station, Rhode Island | US EPA Network

AJ is an air monitoring station located at the W. Alton Jones Campus of URI in Parkerfield, Rhode Island, United States. It is part of the national air quality monitoring network and is operated under the US EPA National Exposure Research Lab. The station is situated in Kent County, Rhode Island, and serves to track ambient air pollutants in a rural setting. The station operates under the US EPA Air Quality System (AQS) framework, which sets standards for criteria pollutants such as ozone, particulate matter, carbon monoxide, sulfur dioxide, and nitrogen dioxide. While specific parameters measured at AJ are not detailed, typical rural monitoring stations in the US measure ozone and fine particulate matter to assess background air quality and regional transport of pollutants. As an operational station, AJ provides valuable data for understanding air quality trends in Rhode Island. Its location on a university campus supports research and public health monitoring. The data collected helps inform regulatory compliance and community awareness of air quality conditions.

The station is located in a rural area of Rhode Island, which is influenced by regional air pollution transport from urban and industrial sources. Monitoring at this site helps characterize background ozone and particulate levels, which are important for assessing compliance with National Ambient Air Quality Standards (NAAQS). The US EPA AQS network ensures consistent data collection and reporting for air quality management.
