In this paper the Secondary Organic Aerosol Processor (SOAP v1. 0) model is presented.
This model determines the partitioning of organic compounds between the gas and particle …

We present a new and considerably extended parameterization of the thermodynamic
activity coefficient model AIOMFAC (Aerosol Inorganic-Organic Mixtures Functional groups …

Tropospheric aerosols contain mixtures of inorganic salts, acids, water, and a large variety of
organic compounds. Interactions between these substances in liquid mixtures lead to …

Air quality models that generate the concentrations of semi-volatile and other condensable
organic compounds using an explicit reaction mechanism require estimates of the physical …

This study presents a new, improved parameterisation of the temperature dependence of
activity coefficients in the AIOMFAC (Aerosol Inorganic–Organic Mixtures Functional groups …

Organic aerosol (OA) models are typically formulated on the basis of empirical parameters
or from first principles based on molecular constituents and properties. The overarching …

The partitioning of semivolatile organic compounds between the gas phase and aerosol
particles is an important source of secondary organic aerosol (SOA). Gas-particle …

A thermodynamic model is presented for predicting the formation of particulate matter (PM)
within an aerosol that contains organic compounds, inorganic salts, and water. Neutral …

In this study, assumptions (ideality and thermodynamic equilibrium) commonly made in
three-dimensional (3-D) air quality models were reconsidered to evaluate their impacts on …

Water plays an essential role in aerosol chemistry, gas–particle partitioning, and particle
viscosity, but it is typically omitted in thermodynamic models describing the mixing within …
