Short summary
Nitrogen oxides (NOx) largely control the ozone budget in the troposphere globally. Dinitrogen pentoxide (N2O5) is an important species as a nighttime reservoir for nitrogen oxides. Loss of N2O5 to aerosol particles is therefore important for the budget of NOx and the oxidation capacity. Here we provide direct evidence for its efficient accommodation into aqueous aerosol particles and its fast dissociation, which has not been elucidated as directly in previous studies.
