Outline of Final Research Achievements

Sulfate aerosols originated from marine production processes in the East China Sea and the effect on cloud fields were examined through marine in-situ measurement, isotope analysis and numerical model simulation. Although the contribution of marine bio-originated aerosols is not considerable over the East China Sea where various types of aerosols co-exist, following results were obtained: Cloud fields showed characteristic features via analyses of active radar and passive radiometer. Seasonal variations of DMS and chlorophyll, and the origin of lead were revealed with marine in-situ measurement and isotope analysis, respectively.
