EGLE adds air quality data to webpage

The Michigan Department of Environment, Great Lakes, and Energy’s (EGLE) Air Quality Division is adding up-to-date information related to the number and type of Air Quality Alerts to its Learn About Air Quality webpage under “How’s my air quality?”

*Some calendar days had both ozone and PM2.5 alerts.


EGLE’s meteorologists call Air Quality Action Days when air quality may be harmful due to high levels of ozone and/or PM2.5 (Particulate Matter). Some calendar days may have high levels of only one pollutant, but there are times when both pollutants are high at the same time. If additional alerts are called, they will be added to the page. Information on 2023 Air Quality Action Days joins other important pieces of information like how to check your air quality and how to protect yourself during wildfire smoke events.  Other links on the page, include:

“Forecasting when weather conditions may create situations where air pollutants can impact the public -- especially sensitive groups, like people with breathing difficulties, children and the elderly -- is so important. The best way to stay informed is to know your AQI and sign up for notifications of Air Quality Action Days”, said Stephanie Hengesbach, Air Quality Division meteorologist.
