Atmospheric OH reactivity was measured in a rainforest and a megacity.
Amazon reactivity peaked by day, was isoprene dominated, and anticorrelated to CO2.
Beijing reactivity peak in rush hour, was dominated by NO2 and correlated with CO2.
With high daytime reactivity in the rainforest, ozone remains low and constant.
Despite lower reactivity in megacity air, ozone increased strongly by day.
