Short summary

Oleic acid is a chemical substance which is emitted from cooking processes and is present as tiny particles in the atmosphere. The oleic acid in the particles reacts chemically with atmospheric ozone, causing substantial changes to the composition of the particles. This paper uses new techniques to explore these chemical reactions and the effect of humidity upon them. The significance of the results for the atmosphere is considered.
