Two-Product

Two-product model for secondary organic aerosol (SOA) formation (Odum et al., 1996). Represents the complex mixture of oxidation products from a reactive organic gas (ROG) as two lumped surrogate products that partition between gas and aerosol phases according to an ideal-solution absorptive-partitioning equilibrium. Yields and saturation concentrations correspond to alpha-pinene oxidation from Seinfeld and Pandis (2006) Table 14.12.
