Description

Three recent studies, 2D-VBS (Donahue et al. 2012), SOM (Cappa and Wilson 2012) and FGOM (Zhang and Seinfeld 2012) are directed at the next generation of secondary organic aerosol (SOA) models. SOA formation and evolution are represented in terms of the competition between functionalization and fragmentation. Each model contains a set of parameters that are to be determined by fitting the model to laboratory chamber data. This poster outlines the features of the Functional Group Oxidation Model (FGOM) and presents its implementation to describe SOA formation from C12 alkanes. The implementation of the FGOM is compared with that of the SOM model.
