How does the map work?

The Map below is coloured based on current air quality index for health (AQIH) staus. It updates every two to five minutes with the most up-to-date calculated Air Quality Index for Health (AQIH) for each station, which colours the station icon according to the air quality and health implications- from good to poor. Detailed information on the AQIH is available at Air Quality Index for Health.

If a station is blue it means that it is a non-automated station and data will only be available following laboratory analysis.

If a station displays no colour (grey) there may be an instrument or communication issue associated with it or it may be undergoing planned maintenance/upgrade.

All EPA air quality reports and the latest air quality bulletin can be viewed here Reports and Bulletins

A list of all the monitoring stations is available here.
