abstract = {[ 1] The formation of aerosols, and subsequent cloud
condensation nuclei, remains one of the least understood
atmospheric processes upon which global climate change
critically depends. Under atmospheric conditions, the
process of homogeneous nucleation (formation of stable
clusters -1 nm in size), and their subsequent growth into
new particles (>3 nm), determines the aerosol and cloud
nuclei population, yet, hitherto, no theory has elucidated
the new particle formation phenomenon in detail. In this
study, we present a new theory which provides a mechanistic
explanation for new particle formation via activation of
stable inorganic clusters by organic vapors. The new
nano-particle activation theory is analogous to Kohler
theory which describes cloud formation in a supersaturated
water vapor field but differs in that it describes the
activation of inorganic stable nano-clusters into aerosol
particles in a supersaturated organic vapor which initiates
spontaneous and rapid growth of clusters. Inclusion of the
new theory into aerosol formation models predicts that
increases in organic vapor densities lead to even greater
increases in particle production, which, in turn, will
influence the global radiative cooling effect of atmospheric
aerosols.},
