Overview
ISWS CLIMATE STATION is an operational air monitoring station in Bondville, Illinois, part of the CASTNET network. It provides long-term atmospheric data for environmental research and regulatory compliance.
ISWS CLIMATE STATION is an air monitoring station located in Bondville, Champaign County, Illinois, United States. Operated under the Clean Air Status and Trends Network (CASTNET), this facility contributes to the national ambient air quality monitoring infrastructure. CASTNET is a key component of the US EPA's Air Quality System (AQS), providing data on criteria pollutants and atmospheric deposition. The station reports to Mactec, Inc and collects continuous air quality measurements, including ozone, sulfur dioxide, and particulate matter, as well as meteorological parameters. Its last sample date was December 24, 2024, indicating active operation. The station's siting in a rural agricultural area of central Illinois provides representative background air quality data for the region, complementing urban monitoring stations. Environmental monitoring at ISWS CLIMATE STATION supports understanding of regional air pollution transport, acid deposition, and climate trends. Data from this station is used by researchers and regulators to assess compliance with National Ambient Air Quality Standards (NAAQS) and to inform policy decisions. The station's long-term record contributes to the global atmospheric monitoring network under the WMO Global Atmosphere Watch program.
Environmental context
The station is situated in the agricultural heartland of Illinois, where air quality is influenced by emissions from farming operations, power plants, and transportation corridors. Monitoring at this site helps track regional haze, ozone formation, and nitrogen deposition, which are critical for assessing ecosystem health and human exposure. The rural location provides a baseline for distinguishing local pollution sources from transported pollutants.
