Air Quality Index (AQI)

Today's Air Quality Index (AQI) is available through the Spatial Air Quality System for all sites in Florida with ozone or continuous fine particle (PM2.5) monitors. The data displayed for the current day use the previous 24 hours for the PM2.5 calculations and the previous 31 hours for the eight-hour average ozone calculations. At midnight, the values for the day are left as calendar-day block averages.

This site provides up to the hour information as well as historic information for the two pollutants that most commonly drive the Air Quality Index in Florida. The default settings display each of the ozone and PM2.5 monitor’s AQI color code. To display either the AQI values or the concentration values, use radio buttons under the Layers tab on the left of the display of the map of Florida. The legend for the AQI is available on the Controls tab, also on the left of the display of the map of Florida.
