| Zusammenfassung |
| The present paper reviews existing knowledge with regard to Organic Aerosol
(OA) of importance for global climate modelling and defines critical gaps
needed to reduce the involved uncertainties. All pieces required for the
representation of OA in a global climate model are sketched out with special
attention to Secondary Organic Aerosol (SOA): The emission estimates of
primary carbonaceous particles and SOA precursor gases are summarized. The
up-to-date understanding of the chemical formation and transformation of
condensable organic material is outlined. Knowledge on the hygroscopicity of
OA and measurements of optical properties of the organic aerosol
constituents are summarized. The mechanisms of interactions of OA with
clouds and dry and wet removal processes parameterisations in global models
are outlined. This information is synthesized to provide a continuous
analysis of the flow from the emitted material to the atmosphere up to the
point of the climate impact of the produced organic aerosol. The sources of
uncertainties at each step of this process are highlighted as areas that
require further studies. |
