| Zusammenfassung |
| This paper synthesizes the available scientific information connecting
atmospheric nucleation with subsequent cloud condensation nuclei (CCN)
formation. We review both observations and model studies related to this
topic, and discuss the potential climatic implications. We conclude that CCN
production associated with atmospheric nucleation is both frequent and
widespread phenomenon in many types of continental boundary layers, and
probably also over a large fraction of the free troposphere. The
contribution of nucleation to the global CCN budget spans a relatively large
uncertainty range, which, together with our poor understanding of
aerosol-cloud interactions, results in major uncertainties in the radiative
forcing by atmospheric aerosols. In order to better quantify the role of
atmospheric nucleation in CCN formation and Earth System behavior, more
information is needed on (i) the factors controlling atmospheric CCN
production and (ii) the properties of both primary and secondary CCN and
their interconnections. In future investigations, more emphasis should be
put on combining field measurements with regional and large-scale model
studies. |
