Spatial clustering characteristics of summer surface ozone and heatwaves spatiotemporal evolution from 2013 to 2020. (a), (d), and (g) are Global Moran’s I for the trends in summer surface ozone concentrations and the number of heatwave days and events; (b), (e), and (h) are the spatial distribution of hot and cold spots for the trends in summer surface ozone concentrations and the number of heatwave days and events; (c), (f), and (i) are the spatial distribution of spatial clustering for the trends in summer surface ozone concentrations and the number of heatwave days and events.
