| Zusammenfassung |
| Secondary organic aerosol (SOA) accounts for a significant fraction of
ambient tropospheric aerosol and a detailed knowledge of the formation,
properties and transformation of SOA is therefore required to evaluate its
impact on atmospheric processes, climate and human health. The chemical and
physical processes associated with SOA formation are complex and varied,
and, despite considerable progress in recent years, a quantitative and
predictive understanding of SOA formation does not exist and therefore
represents a major research challenge in atmospheric science. This review
begins with an update on the current state of knowledge on the global SOA
budget and is followed by an overview of the atmospheric degradation
mechanisms for SOA precursors, gas-particle partitioning theory and the
analytical techniques used to determine the chemical composition of SOA. A
survey of recent laboratory, field and modeling studies is also presented.
The following topical and emerging issues are highlighted and discussed in
detail: molecular characterization of biogenic SOA constituents, condensed
phase reactions and oligomerization, the interaction of atmospheric organic
components with sulfuric acid, the chemical and photochemical processing of
organics in the atmospheric aqueous phase, aerosol formation from real plant
emissions, interaction of atmospheric organic components with water,
thermodynamics and mixtures in atmospheric models. Finally, the
major challenges ahead in laboratory, field and modeling studies of SOA are
discussed and recommendations for future research directions are proposed. |
