### The Atlanta Eight-Hour Ozone Attainment Demonstration 

# Appendix D Scatter Plots of Hourly 8-Hour Ozone, 1-Hour Ozone, NO, and NO2

### Following are scatter plots for hourly 8-hour ozone, 1-hour ozone, NO, and NO2 across all monitors in GA. If a monitor has observed data fo r all of these species, sc atter plots were grouped together for the monitor for each calendar month. If a monitor only has ozone measurements, its ozone scatter plots were grouped together for the mode ling period. Each scatter plot shows observed concentrations of these species along with their concentrations predicted by CMAQ 12km in Georgia from May 24, 2002 to September 12, 2002.Figure 1 Observation-prediction scatter plots for 8-hour ozone, 1-hour ozone, NO, and NO2 concentrations for 05-24 ~ 05-31
