Size distribution and chemical composition of marine aerosols: a compilation and review

摘要: Some 30 years of physical and chemical marine aerosol data are reviewed to derive global-size distribution parameters inorganic particle composition on a coarse 15°×15° grid. There large gaps in geographical seasonal coverage characterisation. About 28% the grid cells contain while there compositional some 60% cells. The size were parametrized terms 2 submicrometer log-normal distributions. sparseness did not allow zonal differentiation By segregating according major sources, sea salt, dimethylsulfide, crustal material, combustion processes other anthropogenic much information mass concentrations contribution natural sources can be gleaned from base. significant meridional differences contributions different aerosol. Very clearly, we see though that global surface atmosphere is polluted by sulfur. Only case sulfur components presentation very distributions which reflect spring blooms appropriate parts oceans. As an example potential value comparing base transport models, MSA compared modelled general good agreement encouraging latitudinal discrepancies warrant further investigations covering such as black carbon metals.
