Air Quality Monitoring Data
Air quality monitoring is conducted across the state of Indiana for a variety of programs; National Ambient Air Quality Standards (NAAQS) compliance, air quality trends, Air Quality Index (AQI), air quality mapping (AIRNow), special monitoring projects, and others. The Network Description [XLS] lists the current sites and the parameters monitored at each site.
A Network Review is conducted annually to determine any changes to be made to the network.
Quality Assurance procedures and guidelines are developed and implemented to ensure the validity and quality of the data collected.
Exceptional Events: Exceedance data are reviewed to determine if the data are affected by an exceptional event
Air Quality Data
Data for the following pollutants are obtained on an hourly basis from the continuous monitoring sites across Indiana:
- Ozone (O3)
- Particulate (PM2.5)
- Particulate (PM10)
- Oxides of Nitrogen (NOx)
- Carbon Monoxide (CO)
- Sulfur Dioxide (SO2)
- Toxics (Indiana ToxWatch Monitoring Sites)
- U.S. EPA Air Toxics at Schools Data
