Figure 7.

Figures 7A and 7B are clustered bar graphs, plotting Mean daily maximum 8-hour average ozone concentrations (micrograms per meter cubed), ranging from 0 to 150 in increments of 50 (left y-axis) for Central-East China (Figure 7A) and Shandong Peninsula (Figure 7B) (right y-axis) across Year, including 2014, 2016, and 2018 (x-axis) for China National Environmental Monitoring Center and Predictions.

The comparison of the summertime (June–July–August) mean MDA8 O3 concentrations between our model predictions and the CNEMC monitoring data over 2014–2019 for selected regions. (A) Central-East China; and (B) the Shandong Peninsula. The blue columns represent the CNEMC observations, and the orange columns represent our model predictions. The height of the columns and the error bars represent the mean MDA8 O3 concentrations and the standard errors. Note: CNEMC, China National Environmental Monitoring Center; MDA8, daily maximum 8-h average; NCP, the North China Plain; O3, ozone; PRD, the Pearl River Delta, YRD: the Yangtze River Delta.
