* A "Smog Alert" does not necessarily mean an exceedance of Federal Air Quality Standards, but is issued to best protect the public health. Forecasts are issued for both Ozone and Particulate Matter. A complete list of Exceedances of Federal Air Quality Standards in Georgia is also available.

Important! 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.
