Vincennes Air Monitoring Station – Southwest Purdue Agricultural Center, Indiana

Vincennes is an air monitoring station located at the Southwest Purdue Agricultural Center in Vincennes, Indiana, United States. It is part of the Clean Air Status and Trends Network (CASTNET), a national network designed to assess the effectiveness of emission reduction programs under the Clean Air Act. The station monitors criteria pollutants and atmospheric deposition, contributing to the US EPA's Air Quality System (AQS) database. As a CASTNET site, Vincennes employs standardized monitoring protocols to measure ozone, sulfur dioxide, nitrogen compounds, and particulate matter, along with meteorological parameters. The network emphasizes siting representativeness, with stations typically placed in rural or agricultural areas to capture regional background conditions. The reporting agency, Mactec, Inc., ensures data quality and continuity, with the most recent sample collected in December 2024. The Vincennes station supports environmental research and regulatory compliance by providing baseline air quality data for the Midwest region. Its agricultural setting helps differentiate local agricultural emissions from transported pollutants, aiding in the development of effective air quality management strategies. The data also contributes to the WMO Global Atmosphere Watch program for understanding hemispheric air pollution trends.

The Vincennes station is situated in an agricultural region of southwestern Indiana, where air quality is influenced by both local farming activities and regional transport from industrial and urban sources. CASTNET's focus on rural sites like Vincennes provides critical data on background ozone and nitrogen deposition, which are key for assessing ecosystem impacts such as eutrophication and crop damage. The station's parameter coverage includes criteria pollutants and meteorological variables, ensuring comprehensive monitoring for regulatory compliance and scientific research.
