Welcome to IDEM’s air monitoring network site. IDEM is in the process of linking all our air monitoring sites into this 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 http://www.in.gov/idem/4652.htm. 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.
