Short summary

Organic nitrates play a crucial role in air pollution, as they are NO_x reservoirs. This work investigated for the first time their reactivity with light in the aqueous phase (cloud and fog and wet aerosol), proving it slower than in the gas phase. Therefore, our findings reveal that partitioning of organic nitrates in the aqueous phase leads to longer atmospheric lifetimes of these compounds and thus a broader spatial distribution of their related pollution.
