(1) The weighted average was derived by adding the three years of individual level data (2000-2002), multiplying the sums of each level by the assigned standard weights, i.e. 1=orange, 1.5=red, 2.0=purple, and calculating the average. (2) States were not included if respective counties got a grade of B or higher. (3) Two states (KY & TN) expanded the length of their ozone monitoring season and 7 states (AL, CT, FL, MA, ME, VT & WA ) shortened the length of their season. Data from the 2004 report reflects the current ozone season by state. No grades were affected by the changed season lengths, although it may be inaccurate to compare weighted averages from this report with previous reports in those states.
