Sand Mountain is an air monitoring station in Crossville, Alabama, operated under the CASTNET network. It provides long-term atmospheric data to assess air quality trends and ecosystem impacts.
Sand Mountain is an air monitoring station located at the Sand Mountain Alabama Agricultural Experiment Station in Crossville, DeKalb County, Alabama, United States. It is part of the Clean Air Status and Trends Network (CASTNET), a national network established by the US EPA to monitor ambient air quality and deposition. The station contributes to the assessment of regional air pollution and its effects on ecosystems. The station operates under the CASTNET framework, which measures criteria pollutants, atmospheric deposition, and meteorological parameters. The reporting agency is Mactec, Inc., and the most recent sample date recorded is December 24, 2024. CASTNET stations are typically equipped with filter packs, continuous analyzers, and meteorological sensors to provide comprehensive data on ozone, sulfur dioxide, nitrogen oxides, particulate matter, and acid deposition. As part of the US EPA's Air Quality System (AQS), Sand Mountain supports regulatory compliance and research on air quality trends. Its location in rural Alabama provides representative background conditions for the southeastern United States. The data collected helps inform policy decisions and public health advisories, contributing to the protection of air quality and ecosystems.
Environmental context
Sand Mountain is situated in a rural agricultural region of northeastern Alabama, where air quality is influenced by local farming activities, regional transport of pollutants, and occasional wildfire smoke. The station's location at an agricultural experiment station allows for monitoring of background air quality conditions, which is critical for understanding the impacts of agricultural emissions and regional haze. CASTNET's focus on long-term trends supports the evaluation of emission reduction programs under the Clean Air Act.
