High Ozone Values During 2009
1-Hour Averages
Values below are maximum 1-hour ozone concentrations measured on the given date in parts per million (ppm). These values are followed by "-" and the number of hourly values exceeding the numerical value of the National Ambient Air Quality Standard (>0.124 ppm). So far there have been none recorded in 2009.

8-Hour Averages
Values below are maximum daily 8-hour ozone concentrations measured in parts per million (ppm), exceeding the value of the revised National Ambient Air Quality Standard (0.075 ppm). The column labeled 4th Max indicates the 4th highest 8-hour average for all days to date, not just the "high" days listed; bold values are those exceeding 0.075 ppm.
Note: compliance with the air quality standard is based on the average of this 4th highest value during the last three years. Therefore, these highlighted values are not, in and of themselves, a violation of the air quality standard, but rather an indication of elevated values. Only after three years of data with the resulting 4th maximum value can a determination of an NAAQS violation be made.
