KEY: AQI = Air Quality Index; R = revised.
NOTES
The Air Quality Index (AQI) integrates information on 6
major pollutants (particulate matter less than 10 microns in diameter,
particulate matter less than 2.5 microns in diameter, sulfur dioxide, carbon
monoxide, ozone, and nitrogen dioxide) across an entire monitoring network
into a single number that represents the worst daily air quality experienced
in an urban area. An AQI greater than 100 indicates that at least 1 criteria
pollutant exceeded air quality standards on a given day; therefore, air quality
would be in the unhealthful range on that day. Air quality monitoring sites are selected
as "trend sites" if they have complete data for at least 8 of the
10 last years.
