Flora-Flora Airport is an air monitoring station located at the Flora Airport in Carroll County, Indiana, United States. The station is operated by the Indiana Department of Environmental Management's Office of Air Quality and is part of the national ambient air quality monitoring network. As a fixed-site monitor, it provides data on criteria pollutants to assess compliance with National Ambient Air Quality Standards (NAAQS). The station operates under the regulatory framework of the US EPA Air Quality System (AQS), which sets standards for monitoring methods, siting, and quality assurance. Typical air monitoring stations in Indiana measure pollutants such as ozone, particulate matter (PM2.5 and PM10), sulfur dioxide, nitrogen dioxide, carbon monoxide, and lead. The station's last reported sample date was September 30, 2025, indicating recent data collection. Environmental monitoring at this location supports public health protection by tracking air quality in a rural area influenced by agricultural activities and transportation. Data from the station helps inform local air quality forecasts and regulatory decisions. The station's location at an airport also provides context for potential emissions from aviation activities.

The station is situated in a rural area of Carroll County, Indiana, where air quality is influenced by agricultural emissions, including ammonia from fertilizers and particulate matter from tilling, as well as vehicle traffic and occasional aviation activity. Monitoring criteria pollutants here helps assess regional background air quality and potential transport of pollutants from nearby urban centers. The station's siting is representative of rural conditions, providing valuable data for understanding non-urban air quality trends.
