Cloud condensation nuclei (CCN) are tiny particles, such as dust, pollen, or pollutants, that serve as surfaces for water vapor to condense upon, forming cloud droplets. The presence of these particles is crucial for cloud formation and influences weather patterns, precipitation processes, and climate dynamics. By facilitating the transition of water vapor to liquid droplets, CCN plays an essential role in the formation of clouds in both terrestrial and extraterrestrial environments.
