Due to low levels of pollen and mold during the winter months, RAPCA has suspended sampling until late winter/early spring.
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.
If your interested in learning more about our area's designation status, please visit Ohio EPA's Attainment Designations page.

NOTE: Ozone data at our NCORE site is collected year-round. The other ozone sites only operate during the official ozone season, which runs from April 1 - October 31.
RAPCA collects pollen & mold data from a Burkard sampler at Sinclair Community College in downtown Dayton. Each 24-hour sample represents approximately 8 AM of the previous day through 8 AM for the day of the report. All of our pollen and mold counts are submitted to the National Allergy Bureau (NAB) for publication.
