Aerosol particles that provide a platform for the condensation of water vapor, resulting in clouds with higher droplet concentrations and increased albedo.

Small particles in the air on which water vapor condenses and forms cloud droplets.

microscopic bits of clay, salt, or solid pollutant around which water vapor condenses in clouds to form raindrops.

Cloud condensation nuclei or CCNs (also known as cloud seeds) are small particles (typically 1/100th the size of a cloud droplet) about which cloud droplets coalesce. See also aerosols.

Airborne particles that serve as an initial site for the condensation of liquid water, which can lead to the formation of cloud droplets. A subset of aerosols that are of a particular size.

Condensed water vapor that is so small that it can only be seen through a microscope. CCN are actually the center of the droplet. Many of these nuclei are tiny salt particles, sulfate or nitrate aeros [..]
