Atmospheric aerosols are very tiny solid or liquid particles suspended in the air. They serve as condensation nuclei for a cloud droplet. So without aerosol particles, clouds could not exist. Although they are present in only very low concentration, they have been identified as key players in numerous processes, such as regulating global climate. They affect the climate as strongly as greenhouse gasses, but acting to cool the Earth when scatter incoming solar radiation. Since more aerosol particles mean more … Continue reading „Aerosol Formation in the Atmosphere“
