abstract = {Secondary organic aerosol components (SOA) contribute
significantly to the activation of cloud condensation nuclei
(CCN) in the atmosphere. The CCN activity of internally
mixed submicron SOA particles is often parameterized
assuming a size-independent single-hygroscopicity parameter
κ. In the experiments done in a large atmospheric reactor
(SAPHIR, Simulation of Atmospheric PHotochemistry In a large
Reaction chamber, Jülich), we consistently observed
size-dependent κ and particle composition for SOA from
different precursors in the size range of
50 nm–200 nm. Smaller particles had higher κ and a
higher degree of oxidation, although all particles were
formed from the same reaction mixture. Since decreasing
volatility and increasing hygroscopicity often covary with
the degree of oxidation, the size dependence of composition
and hence of CCN activity can be understood by enrichment of
higher oxygenated, low-volatility hygroscopic compounds in
smaller particles. Neglecting the size dependence of κ can
lead to significant bias in the prediction of the activated
fraction of particles during cloud formation.},
