A unified framework of semi-volatile partitioning permits models to efficiently treat both semi-volatile primary emissions and secondary organic aerosol production (SOA), and then to treat the chemical evolution (aging) of the aggregate distribution of semi-volatile material. This framework also reveals critical deficiencies in current emissions and SOA formation measurements. The key feature of this treatment is a uniform basis set of saturation vapor pressures spanning the range of ambient…

Fundamental Time Scales Governing Organic Aerosol Multiphase Partitioning and Oxidative Aging.

This paper uses isomer-resolved product measurements of a series of normal-alkanes to distinguish between gas-phase and heterogeneous oxidation products formed by reaction with hydroxyl radicals, and demonstrates the dynamic nature of OA multiphase partitioning and oxidative aging.

Molecular corridors and kinetic regimes in the multiphase chemical evolution of secondary organic aerosol

Abstract. The dominant component of atmospheric, organic aerosol is that derived from the oxidation of volatile organic compounds (VOCs), so-called secondary organic aerosol (SOA). SOA consists of a

Multi-generation gas-phase oxidation, equilibrium partitioning, and the formation and evolution of secondary organic aerosol

Abstract. A new model of secondary organic aerosol (SOA) formation is developed that explicitly takes into account multi-generational oxidation as well as fragmentation of gas-phase compounds, and

Semivolatile POA and parameterized total combustion SOA in CMAQv5.2: impacts on source strength and partitioning.

The model with representation of semivolatile POA improves predictions of hourly OA observations over the traditional nonvolatile model at sites during field campaigns and includes a new surrogate species, potential secondary organic aerosol from combustion emissions (pcSOA), which provides a representation of the secondary organic Aerosol from anthropogenic combustion sources that could be missing from current chemical transport model predictions.

Kinetic modelling of formation and evaporation of SOA from NO3 oxidation of pure and mixed monoterpenes

Abstract. Organic aerosol constitutes a major fraction of the global aerosol burden and is predominantly formed as secondary organic aerosol (SOA). Environmental chambers have been used extensively

Direct measurements of semi-volatile organic compound dynamics show near-unity mass accommodation coefficients for diverse aerosols

The partitioning of low- and semi-volatile organic compounds into and out of particles significantly influences secondary organic aerosol formation and evolution. Most atmospheric models treat

Modeling Secondary Organic Aerosol Formation From Emissions of Combustion Sources

Semi-volatile and reactive primary organic aerosols are modeled on a global scale using the GISS GCM II' “unified” climate model. We employ the volatility basis set framework to simulate emissions,

Exploring Divergent Volatility Properties from Yield and Thermodenuder Measurements of Secondary Organic Aerosol from α-Pinene Ozonolysis.

The volatility parameters thus determined suggest that SOA yields and enthalpies of evaporation are substantially higher, and products less volatile, than is currently assumed in atmospheric models.

Formation of Low-Volatility Organic Compounds in the Atmosphere: Recent Advancements and Insights.

A framework for autoxidation, accretion, and organic salt formation can be described by equilibrium partitioning theory; a framework for which is presented here will facilitate the inclusion of such processes in model representations of SOA formation.

Photochemical Aging Alters Secondary Organic Aerosol Partitioning Behavior

Organic aerosol is the largest fraction of the atmospheric nonrefractory aerosol mass and has a significant impact on climate, visibility, and human health. A significant portion of organic aerosol



Modeling semivolatile organic aerosol mass emissions from combustion systems.

A two-component absorptive-partitioning model is used to investigate gas-particle partitioning of emissions across a wide range of atmospheric conditions, indicating that it is not possible to specify a single value for the organic aerosol emissions.

Estimated effects of temperature on secondary organic aerosol concentrations.

Currently available constant temperature partitioning coefficients do not adequately represent atmospheric SOA partitioning behavior, and air quality models neglecting the temperature dependence of partitioning are expected to underpredict peak SOA concentrations as well as mistime their occurrence.

Critical factors determining the variation in SOA yields from terpene ozonolysis: a combined experimental and computational study.

It is suggested that SOA yields are likely to increase substantially through several generations of oxidative processing of the semi-volatile products, and the connections between fundamental details of physical chemistry and the multitude of steps associated with SOA formation are explored.
