The MPCA’s air monitoring network measures air pollution levels at over 50 locations across Minnesota. The data collected from air monitoring sites are used to determine whether Minnesota meets federal and state air quality standards and health benchmarks, to forecast and report daily air quality through the Air Quality Index, and to track trends in air pollution levels over time.
The Air Monitoring Network Plan summarizes the primary air monitoring activities conducted by the MPCA in Minnesota including proposed changes to the monitoring network for the upcoming year and whether existing monitoring sites meet federal and state air quality standards.
Air pollution monitoring data collected by the MPCA is submitted to the U.S. Environmental Protection Agency each quarter. The U.S. EPA’s AirData website provides public access to air pollution monitoring data from across the country, including Minnesota. The Air data webpage includes more information on air pollution monitoring and emissions data collected by the MPCA.
