Short summary

At high concentrations, tropospheric ozone (O₃) deteriorates air quality. Weather conditions are key to understanding the variability in O₃ concentration, especially during extremes. We suggest that identifying the presence of combined heatwaves is essential to the study of droughts in canopy–troposphere interactions and O₃ concentration. Even so, they are associated, on average, with an increase in O₃, partly explained by an increase in precursor emissions and a decrease in dry deposition.
