Daily Report

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.
