Atmospheric aerosols upon which water vapor can condense at lower supersaturations are called as Cloud Condensation Nuclei (CCN). Only a small fraction of aerosols serve as CCN (about 1% in continental air and about 10–20% in maritime air). Most of the CCN would be a mixture of soluble and insoluble components.
