大気エアロゾル中の硫黄成分と窒素成分の地球化学―発生から沈着まで

抄録

Biogeochemical material cycles between the atmosphere and marine/terrestrial ecosystems, their interactions with climate through atmospheric radiation and clouds, and the impacts of human activities on these processes have become extremely important issues in recent atmospheric chemistry studies. Sulfur and nitrogen components in atmospheric aerosols have attracted considerable attentions in these study areas. This special issue focuses on the sulfur and nitrogen components in atmospheric aerosols and introduces geochemical topics of recent interests in the series of processes from the emission of their precursor gases to the removal by deposition. The purposes of this issue are to summarize the current understanding of these components, to ask what kind of study will be needed in the future, and to help develop new study fields.
