| | 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. |
