Air Quality Index Links


The Air Quality Index (AQI) is an index ranging between 0 and 500 for reporting daily air quality.

The higher the AQI value, the greater the level of air pollution and the greater the health concern.

An AQI value of 100 generally corresponds to the national air quality standard
for the pollutant, which is the level EPA has set to protect public health.
