TL;DR: In this article, the authors reviewed existing knowledge with regard to organic aerosol (OA) of importance for global climate modelling and defined critical gaps needed to reduce the involved uncertainties, and synthesized the information 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 aerosols.

TL;DR: Accounting for partitioning and photochemical processing of primary emissions creates a more regionally distributed aerosol and brings model predictions into better agreement with observations, attribute this unexplained secondary organic-aerosol production to the oxidation of low-volatility gas-phase species.

Chemistry of secondary organic aerosol: Formation and evolution of low-volatility organics in the atmosphere
Jesse H. Kroll,John H. Seinfeld +1 more
TL;DR: A review of the chemistry of the formation and continuing transformation of low-volatility species in the atmosphere can be found in this article, where the primary focus is chemical processes that can change the volatility of organic compounds: oxidation reactions in the gas phase, reaction in the particle phase, and reaction in either phase over several generations.

Secondary organic aerosol formation and transport
TL;DR: In this paper, a Lagrangian trajectory model simulating the formation, transport and deposition of secondary organic aerosol is developed and applied to the Los Angeles area, for the air pollution episode of 27-28 August 1987.
