A42D:
Marine Aerosols and Trace Gases I


Session ID#: 10702

Session Description:
Oceanic emissions of sea salt and organic matter, in particulate form, and of sulfur, halogens and volatile organic compounds, in gaseous form, affect the formation, number concentration, and composition of atmospheric cloud condensation nuclei (CCN) and ice nuclei (IN), and influence the reactive chemistry and lifetime of climate-active gases. This session invites contributions in the general areas of (1) laboratory/field experiments and satellite studies of sea spray production, chemical characterization and optical properties of marine aerosol, sea-surface microlayer composition, marine emissions and photochemistry of halogens, DMS, and volatile organic compounds; (2) regional and global scale modelling of marine aerosol and trace gases; (3) development of innovative instrumentation relevant to air-sea aerosol/gas exchange. Contributions from recent field campaigns for improving process-level understanding of entrainment of aerosol from the upper troposphere and removal mechanisms (both dry and wet deposition) are also encouraged.
