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.
