Heatwaves and ozone pollution pose compounded risks to urban health, but limited vertical insights have hindered understanding of their interaction. Using airship observations and model simulations, this study reveals that heatwaves worsen urban ozone pollution by vertically redistributing precursors, while emission reductions could mitigate heat–ozone extremes in a warming climate.
