雲核としての有機エアロゾル研究の現状

Water soluble inorganic substances such as (NH₄) ₂SO₄ and NaCl in aerosol particles have been considered to serve as the only cloud condensation nuclei (CCN) in the atmosphere. Recent observational studies, however, indicate that some of the organic compounds in aerosols also play an important role in the activation of CCN comparable to the inorganic particles' contribution. This article reviews recent observational and laboratory experiments conducted to measure various physico-chemical properties of organic substances that determine the high activation capability of pure organic particles and that of organic and inorganic mixtures as CCN.
