<P> Aerosols (very fine particles / droplets in the atmosphere) have both direct and indirect effects on Earth's radiative balance . The direct (albedo) effect is generally to cool the planet; the indirect effect (the particles act as cloud condensation nuclei and thereby change cloud properties) is less certain . As per the effects are: </P> <Ul> <Li> Aerosol direct effect . Aerosols directly scatter and absorb radiation . The scattering of radiation causes atmospheric cooling, whereas absorption can cause atmospheric warming . </Li> <Li> Aerosol indirect effect . Aerosols modify the properties of clouds through a subset of the aerosol population called cloud condensation nuclei . Increased nuclei concentrations lead to increased cloud droplet number concentrations, which in turn leads to increased cloud albedo, increased light scattering and radiative cooling (first indirect effect), but also leads to reduced precipitation efficiency and increased lifetime of the cloud (second indirect effect). </Li> </Ul> <Li> Aerosol direct effect .
