Aitken nuclei
|
Aerosol particles with diameters ranging from 2nm to 200nm are typical particles found in the atmosphere. They mainly consist of sea salt, soil particles, and soot particles, and are one of the sources of condensation nuclei necessary for cloud formation. Since their abundance fluctuates in relation to human activity, they are attracting attention as an indicator of environmental pollution sources.
