Abstract

The relative influence of particle sources and sinks in the remote marine boundary layer (MBL) is evaluated to elucidate the principal factors governing MBL aerosol behavior. Processes considered include: dimethyl sulfide (DMS) surface flux; gas phase DMS oxidation to SO2; gas phase SO2 oxidation to H2SO4; SO2 and H2SO4 mass transfer to preexisting particles; H2SO4/H2O nucleation; air entrainment from the free troposphere; deposition to the sea surface; air through clouds cycling and rain scavenging; SO2 oxidation in sea salt aerosols and cloud droplets; and sea-salt particle production at sea surface. These processes combined result in a remarkably robust MBL aerosol in the face of ever-changing conditions.
