Monthly Air Quality Charts

The Evansville EPA tracks Ozone and Particulate Matter (PM2.5) data daily. After each month, air quality data from multiple monitoring sites in Evansville and Vanderburgh County, as well as some monitors in surrounding counties, is compiled. This data is used to chart pollution levels for any given day. Ozone data is tracked from March through October and PM data is tracked all year.
