We use a global aerosol microphysics model to predict the contribution of boundary layer (BL) particle formation to regional and global distributions of cloud condensation nuclei (CCN). Including an observationally derived particle formation scheme, where the formation rate of molecular clusters is proportional to gas‐phase sulfuric acid to the power one, improves modeled particle size distribution and total particle number concentration at three continental sites in Europe.

Impact of nucleation on global CCN

Abstract. Cloud condensation nuclei (CCN) are derived from particles emitted directly into the atmosphere (primary emissions) or from the growth of nanometer-sized particles nucleated in the

Determination of cloud condensation nuclei production from measured new particle formation events

A semi‐analytical expression has been developed that accurately models the population dynamics of an aerosol growing from the detection limit (3 nm) to a characteristic CCN size (100 nm), quantifying

Abstract. The number concentration of cloud condensation nuclei (CCN) formed as a result of anthropogenic emissions is a key uncertainty in the study of aerosol indirect forcing and global climate

Wintertime new particle formation and its contribution to cloud condensation nuclei in the Northeastern United States

Abstract. Atmospheric particles can act as cloud condensation nuclei (CCN) and modify cloud properties and precipitation and thus indirectly impact the hydrological cycle and climate. New particle

Toward Direct Measurement of Atmospheric Nucleation

An instrumental setup to measure atmospheric concentrations of both neutral and charged nanometer-sized clusters concludes that a pool of numerous neutral clusters in the sub–3 nanometer size range is continuously present and neutral nucleation dominates over the ion-induced mechanism, at least in boreal forest conditions.
