What is AQI?

The AQI is an index for reporting daily air quality.  It tells you how clean or polluted your air is, and what associated health effects might be a concern.  The higher the AQI value, the greater the level of air pollution and the greater the health concern.

The AQI is derived by comparison to EPA standards from the following data readings:  Fine Particulate Matter (PM2.5) continuous monitor on Canton City Public Health's 2nd floor roof top and ozone (O3) monitors in Canton, Brewster, and Alliance. The Daily AQI report is based on the air quality for the period of 12 AM of the previous day to 12 AM of the current day. The current day AQI value is updated hourly automatically from the monitor equipment.

The daily air quality index is available by clicking the "Daily Air Quality Index (AQI) Report" link above, or from the Repository and WHBC , or by calling Canton City Public Health at (330) 489-3385. You can also get the current day's AQI value, which is updated hourly, but clicking the "Current Air Quality Index (AQI) (updated hourly)" link above.
