RAPCA submits quality-assured monitoring data each month to U.S. EPA's Air Quality System (AQS) Data Mart. AQS contains ambient air pollution data collected by EPA, state, local, and tribal air pollution control agencies from thousands of monitoring stations.
U.S. EPA's Office of Air Quality Planning and Standards and others rely on this data to assess air quality, assist in Attainment/Non-Attainment designations, evaluate State Implementation Plans for Non-Attainment Areas, perform modeling for permit review analysis, and other air quality management functions.
Please visit U.S. EPA’s Air Data website to access data collected by our agency. Should you have any questions or need help finding a particular data set, please contact us.
