Important: This information is published as soon as the values are detected, and does not imply that the data have passed quality assurance validation procedures.
The AQI converts the measured pollutant concentration in a community's air to a number on a scale of 0 to 500. A AQI level in excess of 100 means that a pollutant is in the unhealthful range on a given day; a AQI level at or below 100 means that a pollutant reading is in the satisfactory range.
In March 2008, EPA strengthened the air quality standards for ground-level ozone, a primary component of smog. These new standards mean that lower levels of ozone will now be reported as unhealthy in the daily smog forecasts and in the Air Quality Index (AQI). This website reflects this change.
