Continuous Air Quality Monitoring

Welcome to IDEM's air monitoring network site. IDEM is in the process of linking all our air monitoring sites into the one easy-to-use site. Approximately 65 percent of Indiana's air monitoring network has now been linked into this system. To view data from monitors not yet on the system, visit IDEM's Air Quality Monitoring Data page. The map below shows the sites currently available. Mouse over the green dots on the map for current air quality data at that location or click on the dots for detailed information and historical data.

Additional air quality monitoring reports are available at this link.

PLEASE NOTE: This data has not been verified by the IDEM and may change. This is the most current data, but it is not official until it has been certified by our technical staff. Data is collected from IDEM ambient monitoring sites and may include data collected by other outside agencies. This data is updated hourly. All times shown are in local standard time unless otherwise indicated.
