TL;DR: Model simulations show that the pure biogenic particle formation mechanism has a much larger relative effect on CCN concentrations in the preindustrial atmosphere than in the present atmosphere because of the lower aerosol concentrations, and the cooling forcing of anthropogenic aerosols is reduced.

TL;DR: In this paper, the authors present number size distributions of > 0.8 nm ions and > 1.8-3.0 nm particles measured with the Neutral cluster and Air Ion Spectrometer (NAIS) at a boreal forest site in Hyytiälä, Finland, during 2006-2007.

TL;DR: In this paper, the authors investigated the frequency of atmospheric new particle formation, formation rates of 10-nm particles, and growth rates in the size range of 10−25nm using at least 1 year of aerosol number size distribution observations at 36 different locations around the world.
