St. Martinville Air Monitoring Station | PAMS Network, Louisiana

St. Martinville is an air monitoring station located at the ULL Cade Research and Experimental Farm in St. Martinville, Louisiana, United States. It is part of the Photochemical Assessment Monitoring Stations (PAMS) network, which focuses on measuring ozone precursors and other pollutants to support air quality management. The station is operated under the State of Louisiana reporting agency. The station operates within the US EPA Air Quality System (AQS) framework, which sets standards for criteria pollutants such as ozone, particulate matter, and nitrogen oxides. PAMS stations are specifically designed to collect detailed data on volatile organic compounds and nitrogen oxides, which are key precursors to ozone formation. The station's location in a rural agricultural area provides representative background measurements for the region. This monitoring station contributes to the broader environmental monitoring infrastructure in Louisiana, supporting the state's efforts to meet National Ambient Air Quality Standards (NAAQS). The data collected helps inform local air quality forecasts and public health advisories, particularly during ozone season. Its long-term operation ensures continuity in tracking air quality trends in the region.

St. Martinville is situated in a rural agricultural area of Louisiana, where air quality is influenced by both local emissions from farming activities and regional transport of pollutants from industrial sources along the Mississippi River corridor. The PAMS network focuses on ozone precursor monitoring, which is critical for understanding photochemical smog formation. The station's siting at a research farm provides representative background conditions, complementing urban monitors in nearby cities like Lafayette and Baton Rouge.
