Short summary
Organic nitrates play a crucial role in air pollution, as they are nitrogen oxide (NOx) reservoirs. This work investigated the reaction products and mechanisms of their reactivity with light in the aqueous phase (cloud and fog conditions and wet aerosol). Our findings reveal that this chemistry leads to the formation of atmospheric nitrous acid (HONO).
