An AQI greater than 100 indicates that at least 1 criteria pollutant exceeded air quality standards on a givenday; 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 atleast 8 of the 10 last years.The major reason for revisions to the historical data for the AQI is that changes in the National Ambient Air Quality Standards (NAAQS) are retroactively applied tothe data for previous years to provide consistent comparisons over time. In addition, data from monitoring stations that have fallen below/surpassed the criterionto qualify as a 'trend site' is excluded/included in the latest calculation of the index.Data for 1999 to 2009 include particulate matter 2.5 micron in diameter (PM 2.5).Particulate matter is the term for solid or liquid particles found in the air.SOURCEU.S. Environmental Protection Agency, Office of Air and Radiation, Air Trends , Air Quality Index Information, available athttp://www.epa.gov/air/airtrends/aqi_info.html as of Dec. 21, 2011.
