The Current Air Quality Index reflects the predominant air pollutant (either PM2.5, PM10, or Ozone*) which is the pollutant with the highest reading in the monitoring network. It is updated hourly. The map below provides information for each monitoring site in the network. Clicking on a specific site will take you to a new window where you can access current day and five-day hourly AQI histories for the air pollutants measured at that site.

*Ozone is only measured during ozone season, May-September.
