more about the AQI
The Department of Natural Resources uses weather forecasts and data from air monitoring sites to determine air quality in the state and notifies residents when pollutants reach unhealthy levels based on the Air Quality Index (AQI). The AQI includes two pollutants that can cause health problems in humans -- ozone and particle pollution.
To protect public health, the DNR may issue an advisory even though pollutant levels at some locations have not yet reached unhealthy levels. Forecasters evaluate weather conditions and typically issue an advisory when pollutant levels are rising and at least one monitor has exceeded the standard.
Notice: Due to agency-wide furloughs, DNR offices will be closed and no air quality forecasts or notices about watches or advisories will be issued on the following days during 2010: 2/15; 5/28; 10/11; 11/26; and 12/27. Current air quality information will continue to be available 24 hours a day, 7 days a week through the Daily Air Quality Hotline (1-866-DAILY AIR) and DNR's Real-time Air Monitoring web site. We apologize for any inconvenience.
