Note: The Actual AQI is calculated from actual measurement. For Particulate Matter the AQI is based on the calculated 24-hour average
concentration, measured from midnight to midnight. For Ozone, the AQI is based on the maximum daily 8-hour average concentration
measured during a given day.
* Days missing an ‘Actual Calculated AQI’ are reported with ‘* No Data’
