Abstract
Aerosol particles play a vital role in atmospheric processes
and the climate as they facilitate the formation of clouds and
precipitation. Secondary organic aerosols (SOA) represent a
significant subclass of atmospheric compounds, and recent
research revealed that they could exist in a semi-solid or glassy
state at low temperatures and relative humidity conditions.
Glassy organic compounds influence ice nucleation, ice growth,
chemical reactions and water uptake of aerosols have an effect on
the pathway of activation of cloud droplets and ice crystals. There
are no proposed mechanisms at the atomic level to describe ice
nucleation on glassy organic aerosol. The present paper reviews
existing knowledge and identify mechanisms regarding glassy
organics in atmospheric aerosols and their implications for
atmospheric processes that affect climate modeling.
