Particulate Matter (PM2.5) Data Map

Particulate Matter (PM2.5) Data Map

Fine particulate matter with a diameter of 2.5 microns or less is created primarily from industrial processes and fuel combustion. These particles are breathed deeply into the lungs. Exposure to particle pollution is linked to a variety of significant health problems ranging from aggravated asthma to premature death in people with heart and lung disease.

IDEM operates 19 continuous PM2.5 monitoring sites that are polled hourly in order to obtain the most current information. Continuous data is available interactively on the map and the table. The other PM2.5 monitoring sites measure PM2.5 over a 24 hour period based on an every 1, 3, or 6 day sampling schedule. A summary of this intermittent PM2.5 data is available under the Quick View Current Monitoring Data Summaries. The new Jeffersonville and Hammond-Purdue sites are in the process of being installed and PM2.5 readings will be available upon completion.
