Air quality, like weather, can change from day to day or with greater frequency. The Air Quality Index (AQI) is a tool that provides citizens of Connecticut with the daily forecast of local air quality. Along with the forecasted daily AQI, the Air Quality Index webpage provides the most up to date ozone forecast. Ozone is monitored because it contributes to the majority of unhealthy air quality days in CT during the warmer months.
Operators of emergency engines are required to check the daily AQI forecast before performing any testing.
