| | AQI by Site |
| | AQI is determined using real-time data measured at each site. AQI is based on the pollutant that measured highest. |
| | Factors such as site capabilities, seasonality, wildfire or wind events, and/or technical difficulties influence which |
| | pollutant is used to determine AQI. The data in this report is preliminary and subject to change. |
