Sea-salt aerosol source functions and emissions

摘要: Sea spray aerosols are important for a wide variety of processes. Part the current interest is their role in climate (Penner et al., 2001). aerosol contributes to atmospheric cooling because they scatter incoming solar radiation. It natural component system and therefore can not be regarded as forcing component. However, it often neglected global models may responsible feedback effects. Latham Smith (1990) suggested that changing would alter surface winds thus sea emissions. Although number concentrations very high compared those anthropogenic such ammonium sulphates, significant oceans cover 70% Earth, whereas rather locally produced.
