Short summary
This study investigates the synergistic role of transported regional haze in increasing local inorganic aerosols. PM2.5 data measured at Seoul, South Korea, together with a thermodynamic model show that the transported haze particles from the polluted continent are richer in inorganics and wetter than the local haze particles. The transported wet particles readily increase the inorganic aerosols through the uptake of HNO3 in NOx- and NH3-rich urban environments like Seoul.
