Short summary
To better understand the impact of long-range atmospheric transport of East Asian pollutants over the western North Pacific, we conducted a long-term (2001–12) study on carbonaceous aerosols over the WNP, which demonstrates that the photochemical formation of WSOC and its contributions to SOA have increased over the western North Pacific via long-range atmospheric transport. Biomass-burning-derived carbonaceous aerosols have increased, while primary fossil-fuel-derived aerosols have decreased.
