**The AQI

This is the Air Quality Index.  This measure of air quality is designed to be independent of the pollutants that are in the air. Each pollutant's concentration is measured and given an individual index based upon its effect on human health. The highest of these individual indices is the AQI for the day. The range for the AQI is 0-500 and is related to air quality as follows:
