Sea Salt Aerosol Production Mechanisms, Methods, Measurements, and Models

Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 152.Sea salt aerosol (SSA) exerts a major influence over a broad reach of geophysics. It is important to the physics and chemistry of the marine atmosphere and to marine geochemistry and biogeochemistry generally. It affects visibility, remote sensing, atmospheric chemistry, and air quality. Sea salt aerosol particles interact with other atmospheric gaseous and aerosol constituents by acting as sinks for condensable gases and suppressing new particle formation, thus influencing the size distribution of these other aerosols and more broadly influencing the geochemical cycles of substances with which they interact. As the key aerosol constituent over much of Earth''s surface at present, and all the more so in pre-industrial times, SSA is central to description of Earth''s aerosol burden.
