| | AQI by Site |
| | AQI is based on measured data at each site. Some sites measure only ozone or only PM-2.5. In summer only |
| | those sites with ozone measurements estimate the AQI correctly, and in winter only those sites with PM-2.5 |
| | measurements estimate the AQI correctly. The information in this report is based on preliminary data and is |
| | subject to change. The real-time PM-10/PM-2.5 monitoring eqiupment is used for air quality forecasting and |
| | trend analysis. |
