Short summary
The scarcity of kinetic data for key aerosol aqueous-phase reactions contributes to large uncertainties in atmospheric models. We establish a computational strategy to rapidly predict acid-catalyzed hydrolysis kinetics of organic hydroperoxides, an aerosol constituent with high abundance. The kinetic parameters can be integrated into atmospheric models to improve simulations of the global hydrogen peroxide budget and secondary organic aerosol production.
