What is Cloud Condensation Nuclei?

Cloud condensation nuclei are tiny particles in the atmosphere, such as dust, salt, or pollutants, that provide surfaces for water vapor to condense upon, leading to the formation of cloud droplets. These particles are critical in the cloud formation process, influencing cloud properties and precipitation.
