| Session Description | Marine aerosols exert an important influence on the global and regional climate because of their huge amounts and roles acting as cloud condensation nuclei. Interactions between sea-salt aerosols and anthropogenic gaseous pollutants have been reported to change oxidation capacity and affect air quality in coastal atmospheres. However, most studies are limited in oligotrophic or high latitude oceanic environments. In middle and low latitude oceanic environments such as those eutrophication marginal seas, the atmospheric behaviors, especially generation of ocean-derived biogenic and sea-salt aerosols, the interactions with anthropogenic air pollutants, as well as their environmental and climatic impacts remain largely unknown. With an increasing concern on air quality in coastal atmospheres, the impact of sea haze on marine traffic and unexpected variations of cloud/precipitation over marginal seas and coastal areas in Asia, etc., great efforts are required and essential to improve our understanding of the ocean-derived aerosols and their atmospheric behaviors in the eutrophication marginal seas and the proximity coastal areas. This session will focus on a series of processes of generation, diffusion, chemical evolution and deposition of marine aerosols, activation of cloud condensation nuclei and impacts on cloud and precipitation investigated by laboratory measurements, field experiments and numerical simulation. We also welcome those studies in oligotrophic or high latitude oceanic environments because the comparison can help to deepen our understanding in this field. |
