During the summer, most of the ultrafine particles were volatile particles, which were composed of H_2SO_4, CH_3SO_3H and sulfates bi-sulfates. The abundance of non-volatile particles was ~ 20% during the summer, increasing to>90% in winter-spring. Non-volatile particles in winter were dominantly sea-salt particles. Some ultrafine sea-salt particles might be released from sea-ice. When air mass was transported from the free troposphere over the Antarctic continent, the abundance of non-volatile particles dropped to<30% even in winter.}, pages = {541--553}, title = {南極対流圏中の超微小粒子の揮発特性とその季節変化}, volume = {54}, year = {2010}, yomi = {ハラ, ケイイチロウ and オサダ, カズオ and ニシダ, チハル and ヤブキ, マサノリ and ハヤシ, マサヒコ and ヤマノウチ, タカシ and ワダ, マコト and シオバラ, マサタカ} }
