Spatiotemporal correlation features between surface ozone, heatwaves, and residents’ mental health. (a–c) Spatial distribution of the correlation between summer surface ozone concentrations, heatwave days, and heatwave events with MHQs from 2013 to 2020; (d–f) Correlation coefficients between MHQs and summer surface ozone concentrations, heatwave days, and heatwave events, and their respective correlations with summer surface ozone concentrations and the number of heatwave days and heatwave events from 2013 to 2020.
