APPENDIX B: Valid 4th high maximum daily 8-hour ozone concentrations in nonattainment/attainment areas of the OTR.
Tables of the 4th maximum daily 8-hour ozone concentrations recorded at individual monitors in OTR nonattainment/attainment areas for the 1997-2005 ozone seasons. Hourly data was downloaded from the U.S. EPA AQS database and 8-hour averages were calculated using procedures specified in EPA’s “GUIDELINE FOR DATA HANDLING CONVENTIONS FOR THE 8-HOUR OZONE NAAQS” with flagged (due to a regional forest fire smoke event) data eliminated from the analysis. “***” indicates years during which a monitor was not in operation or had less than 75percent data collection during the ozone season.
