Extended Data Fig. 2: Map of the fractional contribution of radical loss pathways with and without shipping emissions in 1970.
From: Suppression of surface ozone by an aerosol-inhibited photochemical ozone regime

Average simulated July noon-time fraction of radical termination at the surface that occurs through the OH + NO2, peroxy radical self-reactions and aerosol uptake of HO2 for 1970 in the model with and without shipping emissions.
