Daily Report

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.
