The report below displays data on the total number of days with an Air Quality Index Value of over 100.
This data has been compiled from 1990-2007, and represents readings from over 100 monitoring stations throughout the country.
The number of days are an average of the monitoring stations. Of course, data like this is hard to draw many conclusions from
since the data varies greatly based upon individual monitoring station, but the results do provide a high-level look at
nationwide trends.
