Short summary
The atmospheric decomposition of the biogenic α-phellandrene with ozone is characterised by conducting carefully controlled experiments in a smog chamber. Major gas-phase products are identified based on theoretical/mechanism insight, with yields quantified. Meanwhile, a significant amount of aerosol is formed and characterised, with Criegee intermediates found to be important for new particle formation. It is concluded that α-phellandrene contributes to aerosol formation/growth where emitted.

To understand how emission controls will impact ozone, an understanding of the sources and sinks of OH and the chemical cycling between peroxy radicals is needed. This paper presents measurements of OH, HO2, and total RO2 taken in central Beijing. The radical observations are compared to a detailed chemistry model which shows that under low NO conditions there is a missing OH source. Under high NOx conditions, the model under-predicts RO2 and impacts our ability to model ozone.

Biomass burning releases many lower molecular weight organic species which are difficult to analyse, but important to the formation of organic aerosol. This study examined a new high-resolution technique to a better characterise these difficult to analyse organic components. Some burning sources analysed in this study, such as cow dung cake and municipal solid waste, released extremely complex mixtures containing many thousands of different lower-volatility organic compounds.

Aromatic volatile organic compounds (VOCs) emitted from anthropogenic activity are important for tropospheric ozone and secondary organic aerosol (SOA) formation. Here we present a detailed chemical characterisation of SOA from four C9-aromatic isomers and a polycyclic aromatic hydrocarbon (PAH). We identify and compare their oxidation products in the gas and particle phases, showing the different relative importance of oxidation pathways and proportions of highly oxygenated organic molecules.

This work expands upon the recently developed multivariate relative rate technique, presented in Shaw et al. (2019), for the measurement of rates of reaction between aromatic and aliphatic volatile organic compounds (VOCs) and OH. Knowledge of the rates of such reactions are important for understanding air quality in urban environments. This work also provides a key validation of structure–activity relationship models, which provide a theoretical method for estimating OH + VOC kinetics.

We collected high frequency air particle samples (PM2.5) in Beijing (China) and Delhi (India), and we compared the concentration of PAHs in day- and night-time. PAHs were higher in Delhi than Beijing, and the 5 ring PAHs (representative of vehicle emissions) contribute the most to the total PAH concentration. We compared the emission sources and we identified the major sectors that could be subject to mitigation measures. PAH cancer risk estimation in Delhi was 2.2 times higher than Beijing.

Significant air quality problems exist in megacities like Beijing, China. To manage air pollution, legislators need a clear understanding of pollutant emissions. However, emissions inventories have large uncertainties, and reliable field measurements of pollutant emissions are required to constrain them. This work presents the first measurements of traffic-dominated emissions in Beijing which suggest that inventories overestimate these emissions in the region during both winter and summer.

A common way of measuring trace gases in the atmosphere is chemical ionization mass spectrometry. One large drawback of these instruments is that they require radioactive ion sources. In this work we demonstrate a simple ion source that uses a small krypton lamp that can be used to replace a radioactive source.

We characterized non-refractory submicron particulate matter (PM1.0) during winter in Guangzhou, south China. Chemical composition and key sources of ambient PM1.0 are revealed, highlighting the significant role of SOA. The relationship with SOA and peroxy radicals indicated gas-phase oxidation contributed predominantly to SOA formation during non-pollution periods, while heterogeneous/multiphase reactions played more important roles in SOA formation during pollution periods.

Using the chemical composition of offline filter samples, we report that a large share of oxidized organic aerosol in Beijing during summer is due to isoprene secondary organic aerosol (iSOA). iSOA organosulfates showed a strong correlation with the product of ozone and particulate sulfate. This highlights the role of both photochemistry and the availability of particulate sulfate in heterogeneous reactions and further demonstrates that iSOA formation is controlled by anthropogenic emissions.

Unsaturated organic compounds are emitted in large quantities from natural and human-influenced sources. Atmospheric removal occurs significantly by reaction with ozone, initiating reaction sequences forming free radicals and organic pollutants in the gaseous and particulate phases. Due to their very large number, it is impossible to study the reaction rate for every compound, and most have to be estimated. Updated and extended estimation methods are reported for use in atmospheric models.

Large gaps still exist in modeled and observed secondary organic aerosol (SOA) mass loading and properties. Here we investigated the impacts of water partitioning into organic aerosol and nonideality of the organic–water mixture on SOA over eastern China using a regional 3D model. SOA is increased more significantly in humid and hot environments. Increases in SOA further cause an enhancement of the cooling effects of aerosols. It is crucial to consider the above processes in modeling SOA.

We carried out a one-year PM concurrent observation at 12 sites across six regions of China, and size-segregated PAHs were measured. We found both PAHs and BaPeq were concentrated in PM1.1, the northern China had high PAHs pollution and inhalation cancer risk than the southern China, nationwide increases in both PAH levels and inhalation cancer risk occurred in winter. We suggest reduce coal and biofuel consumption in the residential sector is an important option to mitigate PAHs’ health risks.

The composition and light-induced evolution of a water-soluble organic carbon mixture from fresh biomass burning aerosols was investigated with direct infusion electrospray ionisation high-resolution mass spectrometry (HRMS) and liquid chromatography coupled with HRMS. Our findings indicate that the water-soluble organic fraction of combustion-derived aerosols has the potential to form more oxidised organic matter, contributing to the highly oxygenated nature of atmospheric organic aerosols.

Based on measurements from an online mass spectrometer, we quantify volatile organic compounds (VOCs) concentrations from numerous ions of the mass spectrometer, using information from laboratory obtained calibration results. We find that most of these concentrations are from oxygenated VOCs (OVOCs). We further show that these OVOCs also contribute significantly to OH reactivity. Our results suggest the important roles of OVOCs in VOCs emission and chemistry in urban air.

Based on the analysis of the morphology and mixing structure of the activated and un-activated particles, our results emphasize the role of in-cloud processes on the chemistry and microphysical properties of individual activated particles. Given that organic coatings may determine the particle hygroscopicity and heterogeneous chemical reactivity, the increase of OM-shelled particles upon in-cloud processes should have considerable implications in their evolution and climate impact.

The paper details atmospheric chemistry in a mega-city (Beijing), focussing on radicals which mediate the formation of secondary pollutants such as ozone and particles. Highly polluted conditions were experienced, including the highest ever levels of nitric oxide (NO) with simultaneous radical measurements. Radical concentrations were large during “haze” events, demonstrating active photochemistry was occurring. Modelling showed that our understanding of the chemistry at high NOx is incomplete.

An inter-laboratory comparison exercise was conducted for the first time to examine the difference of water-soluble inorganic ions (WSII) measured by 10 labs using Ion Chromatography and by 2 online Aerosol Chemical Speciation Monitor method. Major ions including SO42−, NO3−, NH4+ agreed well in 10 IC labs, and correlated well with ACSM. WSII inter-lab variability strongly affected aerosol acidity results based on ion balance, but aerosol pH computed by ISORROPIA-II were very similar.

Air quality in Beijing is of concern to both policy makers and the general public. In order to address concerns about air quality it is vital that the sources of atmospheric pollutants are understood. This work presents the first top-down measurement of volatile organic compound (VOC) emissions in Beijing. These measurements are used to validate the emissions inventory and assess the impact of VOC emission from the city centre on atmospheric chemistry.

We utilized a novel online mass spectrometry method to measure the total concentration of higher alkanes at each carbon number at two different sites in China, allowing to take into account SOA contributions from all isomers for higher alkanes. We found that higher alkanes account for significant fractions of SOA formation at the two sites. The contributions are comparable or even higher than single-ring aromatics, the mostly recognized SOA precursors in urban air.

As ship emissions impact air quality in coastal areas, ships are required to switch their fuel from high-sulfur residual fuel oil to
low-sulfur diesel or heavy oil in emission control areas (ECA). Our study reveals that while this policy did result in a large drop in ship emissions of particulate matter and sulfur dioxide, emissions of volatile organic compounds (VOCs), however, became over 10 times larger and therefore risks ozone pollution control in harbor cities.

We report the formation of secondary pollutants in the urban Megacity of Beijing that are typically associated with remote regions such as rainforests. This is caused by extremely low levels of nitric oxide (NO), typically expected to be high in urban areas, observed in the afternoon. This work has significant implications for how we understand atmospheric chemistry in the urban environment, and thus how to implement effective policies to improve urban air quality.

Seasonal atmospheric processing of NOCs was investigated using single-particle mass spectrometry in urban Guangzhou. The abundance of NOCs was found to be strongly enhanced by internal mixing with photochemically produced secondary oxidized organics. A multiple linear regression analysis and a positive matrix factorization analysis were performed to predict the relative abundance of NOCs. More than 70 % of observed NOCs could be well explained by oxidized organics and ammonium.

This study investigates SOA formation and particle growth from α-pinene, limonene and m-cresol oxidation through NO3 and OH radicals and the effect of relative humidity. The formed SOA is comprehensively characterized with respect to the content of OC/EC, WSOC, SOA-bound peroxides and SOA marker compounds. The findings present new insights and implications of night-time chemistry which can form SOA more efficiently than OH radical reaction during day-time.

The impact of isoprene on atmospheric chemistry is dependent on how its oxidation products interact with other pollutants, specifically nitrogen oxides. Such interactions can lead to isoprene nitrates. We made measurements of the concentrations of individual isoprene nitrate isomers in Beijing and used a model to test current understanding of their chemistry. We highlight areas of uncertainty in understanding, in particular the chemistry following oxidation of isoprene by the nitrate radical.

BSOA formation is affected by human activities, which are not well understood in polluted areas. In the polluted PRD region, we find that monoterpene SOA is aged, which probably results from high Ox and sulfate levels. NOx levels significantly affect isoprene SOA formation pathways. An unexpected increase of β-caryophyllene SOA in winter is also highly associated with enhanced biomass burning, Ox, and sulfate.

Hygroscopicity is one of the most important properties of aerosol particles, and a number of experimental techniques, which differ largely in principles, configurations and cost, have been developed to investigate hygroscopic properties of atmospherically relevant particles. Our paper provides a comprehensive and critical review of available techniques for aerosol hygroscopicity studies.

We present the design and operation of a newly built continuous-flow reactor (CFR), which can be used as a tool to gain considerable insights into the composition and physical state of secondary organic aerosol (SOA). The CFR was used to generate large quantities of SOA mass, allowing the use of highly accurate techniques that are not usually accessible. We demonstrate how this unique approach can be used to investigate the relationship between SOA formation and physiochemical properties.

The effects of the chemical composition and size of sea-salt-containing particles on their cloud condensation nuclei activity are incompletely understood. Our results showed that submicron sea-salt-containing particles can enrich in small cloud droplets, likely due to change in the chemical composition, while supermicron sea-salt-containing particles tended in the large cloud droplets less affected by chemical composition. This difference might further influence their atmospheric residence time.

Organic compounds are emitted in large amounts from natural and human-influenced sources. Peroxy radicals are key intermediates formed during oxidation of organic compounds, and play a central role in mechanisms forming pollutants such as ozone and organic particles. Due to the large number of different peroxy radicals formed, it is impossible to study the rates of all of their reactions, and most have to be estimated. Updated and new estimation methods are reported for use in atmospheric models

During the winter monsoon, air quality on the east coast of Peninsular Malaysia is influenced by local emissions and aged emissions transported from highly polluted East Asian regions. Atmospheric particulate matter has been sampled at a rural coastal location, and ion chromatography has been used to make time-resolved measurements of the major atmospheric ions present. Analysis of aerosol composition and back trajectories has provided an insight into common sources and formation pathways.

We present observation-based evaluations of the reduction of ambient VOCs under intervention control measures during APEC China 2014 in Beijing and the contributions of emissions from domestic solid fuel burning to ambient VOCs during winter heating. Controlling vehicle exhaust and solvent use was found to be effective in reducing ambient VOCs in non-heating periods, and controlling emissions from residential burning of solid fuels became much more important during winter heating.

POA and SOA from seven heated cooking oil emissions were investigated in a smog chamber. We found that PMF analysis separated POA and SOA better than the residual spectrum method and the traditional method, assuming first-order POA loss. The PMF factors mass spectra were compared with those of ambient PMF factors. Our results suggest that COA source analysis from ambient data is likely complicated by the cooking style and atmospheric oxidation conditions.

Organic compounds are emitted in large quantities from natural and human-influenced sources. Removal from the atmosphere occurs mainly by reaction with hydroxyl (OH) radicals, and initiates reaction sequences forming pollutants such as ozone and organic particles. Due to their very large number, it is impossible to measure the removal rate for all compounds, and most have to be estimated. An updated and extended estimation method is reported for use in atmospheric models and impact assessments.

Stabilised Criegee intermediates (SCIs) are formed in the reaction of alkenes with ozone, both of which are ubiquitous throughout the troposphere. We determine the fate and global distribution of SCI from monoterpene ozonolysis. One major fate of SCI is reaction with H2O, but for a fraction of SCIs, unimolecular reactions dominate. Concentrations of SCIs are high enough regionally to play a key role in the conversion of sulfur dioxide to aerosol, affecting air quality and climate.

While oceanic air is generally thought to be clean, the air pollution over waters in proximity to the coasts is not well recognized. This research indicated that ozone was higher over South China Sea (SCS) than that in the adjacent continental area, while continental anticyclone, tropical cyclone and land breeze favored O3 formation over SCS. In addition, weaker NO titration and stronger atmospheric oxidative capacity led to higher O3 production efficiency over SCS.

The lifetime of a chemical in the atmosphere is largely governed by the rate of its reaction with the hydroxyl radical (OH). Measurements of rates for many of the thousands of identified volatile organic compounds (VOCs) have yet to be determined experimentally. We have developed a new technique for the rapid determination of gas-phase rate coefficients for the simultaneous reactions between multiple VOCs and OH. The method is tasted across a range of scenarios and is used to derive new values.

This paper presents the first radical observations made in London and subsequent model comparisons. This work highlights that there are uncertainties in the degradation mechanism of complex biogenic and diesel-related VOC species under low-NOx conditions and under high-NOx conditions there is a missing source of RO2 radicals. The impact of these model uncertainties on in situ ozone production as a function of NOx is discussed.

The mixing state of black carbon (BC)-containing particles and the mass scavenging efficiency of BC in cloud were investigated at a mountain site (1690 m a.s.l.) in southern China. The measured BC-containing particles were internally mixed extensively with sulfate, and thus the number fraction of scavenged BC-containing particles is close to that of all the measured particles. BC-containing particles with higher fractions of organics were scavenged relatively less.

Primary emissions and aging of open straw burning plumes were characterized in ambient dilution conditions in a chamber. Rich in alkenes, the plumes have high O3 formation potential. The emissions of specific particulate and gaseous compounds were less when the straws were fully burned. Organic aerosol (OA) mass increased by a factor of 2–8 with 3–9 h photo-oxidation, yet > 70 % of the mass cannot be explained by the known precursors. OA gained more O- and N-containing compounds during aging.

The atmospheric decomposition of the biogenic α-phellandrene with ozone is characterised by conducting carefully controlled experiments in a smog chamber. Major gas-phase products are identified based on theoretical/mechanism insight, with yields quantified. Meanwhile, a significant amount of aerosol is formed and characterised, with Criegee intermediates found to be important for new particle formation. It is concluded that α-phellandrene contributes to aerosol formation/growth where emitted.

The chemical budgets and principal sources of ROx and NO3 radicals during a multi-day photochemical smog episode in Hong Kong are elucidated by an observation-constrained MCM model. NO3 was shown to be an important oxidant even during daytime in a pollution case when high aerosol loading attenuated the solar irradiation. This study suggests the potential important role of daytime NO3 chemistry in polluted atmospheres under conditions with the co-existence of abundant O3, NO2, VOCs, and aerosols.

This study investigates the contribution of diesel vehicle emissions to organic aerosol formation and particulate matter concentrations in London. Comparisons of simulated pollutant concentrations with observations show good agreement and give confidence in the skill of the model applied. The contribution of diesel vehicle emissions, which are currently not included in official emissions inventories, is demonstrated to be substantial, indicating that more research on this topic is required.

This paper presents field measurements of HONO and a range of other gas phase and particulate species from an urban background site in London. The measured daytime HONO cannot be reproduced with a simple box model and thus a significant daytime missing source of HONO is present. We show that this missing source could be responsible for 40 % of the OH radical source and 57 % of the OH initiation; hence its potential importance for atmospheric oxidation and ozone production.

This paper first presents an estimate of the real part of the refractive indices and effective densities of chemically segregated aerosols in China. The results indicate the presence of spherical or nearly spherical shape for the majority of particle types. While sharing refractive index in a narrow range (1.47–1.53), they exhibited a wide range of effective density (0.87–1.51). Detailed relationship between physical and chemical properties benefits future research on visibility and climate.

The formation of SOA and sulfate aerosols from the photooxidation of gasoline vehicle exhaust (GVE) when mixing with SO2 was investigated in a smog chamber. We found that the presence of GVE enhanced the conversion of SO2 to sulfate predominantly through reactions with stabilized Criegee intermediates. On the other hand, the elevated particle acidity enhanced the SOA production from GVE. This study indicated that SO2 and GVE could enhance each other in forming secondary aerosols.

Atmospheric isoprene oxidation has an important effect on the formation of pollutants such as ozone and particles. A reliable representation is an essential component of climate change/air quality models. Systematic updates to the detailed chemistry in the MCM are described, with reference to recently reported kinetic/mechanistic data. Results of box model calculations are used to illustrate the impacts of the updates, with particular focus on the key atmospheric cycles involving HOx and NOx.

A detailed chemical mechanism including 205 reactions is developed for use in the Master Chemical Mechanism. With this new chlorine mechanism, it was found that the nocturnal formation of ClNO2 has high potential to perturb the next day's atmospheric photochemistry, by enhancing the radical production and cycling, VOC oxidation and O3 formation, in the polluted coastal environments.

Technological shifts between fuel sources have had unexpected impacts on atmospheric composition and these significant changes can go undetected if source-specific monitoring infrastructure is not in place. We present chemically comprehensive, continuous measurements of organic compounds in a developed megacity (London), that show diesel-related hydrocarbons can dominate reactive carbon and ozone formation potential, highlighting a serious underestimation of this source in emission inventories.

Stabilised Criegee intermediates (SCIs) are formed through alkene-ozone reactions, which occur throughout the atmospheric boundary layer. Recent direct laboratory studies have shown that SCI react rapidly with SO2, NO2 and other trace gases, affecting air quality and climate. We present experimental data from the EUPHORE atmospheric simulation chamber, in which we determine the effects of the ozonolysis of isoprene, on the oxidation of SO2 as a function of H2O and dimethyl sulfide concentration.

This paper describes a new ensemble methodology for the statistical analysis of atmospheric gas- & particle-phase composition data sets. The methodology reduces the huge amount of data derived from many chamber experiments to show that organic reactivity & resultant particle formation can be mapped into unique clusters in statistical space. The model generated is used to map more realistic plant mesocosm oxidation data, the projection of which gives insight into reactive pathways & precursors.

We present a case study of BC wet removal by examining aerosol properties in three biomass burning plumes, one of which passed through a precipitating cloud. Nucleation scavenging preferentially removed the largest and most coated BC-containing particles. Calculated single-scattering albedo (SSA) showed little variation, as a large number of non-BC particles were also present in the precipitation-affected plume.

Biomass fuels used for domestic purposes in east Africa produce a significant atmospheric burden of aerosols and volatile organic compounds. The chemical properties and composition of these aerosols have not been investigated in the laboratory. In this work methanol extracts from filter samples of aerosol collected from an indoor smog chamber were analyzed to determine the chemical composition and identify the light absorption properties of organic aerosol constituents.

Biogenic and anthropogenic air masses mix in the atmosphere, bringing plant-emitted monoterpenes and traffic-related nitrogen oxides together. There is debate whether the presence of nitrogen oxides reduces or increases secondary aerosol formation. This is important as secondary aerosols have cooling effects in the climate system but also constitute a health risk in populated areas. We show that the presence of NOx alone should not much affect the mass yields of secondary organic aerosols.

Aromatic volatile organic compounds (VOCs) emitted from anthropogenic activity are important for tropospheric ozone and secondary organic aerosol (SOA) formation. Here we present a detailed chemical characterisation of SOA from four C9-aromatic isomers and a polycyclic aromatic hydrocarbon (PAH). We identify and compare their oxidation products in the gas and particle phases, showing the different relative importance of oxidation pathways and proportions of highly oxygenated organic molecules.

When exposed to glyoxal in chamber experiments, dry ammonium or methylammonium sulfate particles turn brown immediately and reversibly without increasing in size. Much less browning was observed on wet aerosol particles, and no browning was observed with sodium sulfate aerosol. While estimated dry aerosol light absorption caused by background glyoxal (70 ppt) is insignificant compared to that of secondary brown carbon overall, in polluted regions this process could be a source of brown carbon.

A series of OH-initiated oxidation experiments of trimethylbenzene were investigated in the absence and presence of NOx. Many C9 products with 1–11 oxygen atoms and C18 products presumably formed from dimerization of C9 peroxy radicals were observed, hinting at the extensive existence of autoxidation and accretion reaction pathways. The presence of NOx would suppress the formation of highly oxygenated C18 molecules and enhance the formation of organonitrates and even dinitrate compounds.

Smoke from combustion of a wide range of biomass fuels (e.g., leaves, twigs, logs, peat, and dung) was photochemically aged in a small chamber for up to 8 d of equivalent atmospheric aging. Upon aging, the particle chemical composition and ability to absorb sunlight changed owing to reactions in both the gas and particulate phases. We developed a model to explain the observations and used this to derive insights into the aging of smoke in the atmosphere.

The methods used to estimate the vapour pressures of compounds in the atmosphere typically perform poorly when applied to organic compounds found in the atmosphere. New measurements have been made and compared to previous experimental data and estimated values so that the limitations within the estimation methods can be identified and in the future be rectified.

This paper presents important results on the atmospheric chemistry of combustion emissions. Organic compounds from these emissions can contribute significantly to chemical and physical properties of atmospheric aerosols. In this paper, a detailed chemical analysis of gas- and particle-phase polar organic compounds from the laboratory combustion of globally important fuels is presented. The aging experiments were performed to understand the fate of biomass-burning organics in the atmosphere.

Long-chain alkanes (a large fraction of diesel fuel and its exhaust) are important potential contributors of SOA. Through the analysis of the components of formed SOA, we found that low-temperature conditions promote the oligomerization of n-dodecane, and the degree of oligomerization can reach tetramerization. The presence of the oligomers enhances the light extinction of the particles. UV-scattering particles in the boundary layer can accelerate photochemical reactions and haze production.

The mechanism and factors controlling the hygroscopicity of black-carbon-containing particles (BCPs) from different carbon sources are not well understood. We thoroughly characterized the chemical and compositional properties of 15 samples of BCPs from different sources (wood, herb, and soot) and further investigated their hygroscopicity. Depending on the carbon source, organic carbon and dissolved mineral contents were key determinants of the equilibrium and kinetics of water uptake by BCPs.

To understand the role of aerosol particles in the atmosphere, it is necessary to know their detailed chemical composition and physical properties, especially volatility. The thermal desorption data from FIGAERO–CIMS provides both but are difficult to analyse. With positive matrix factorisation, we can separate instrument background from the real signal. Compounds can be classified by their apparent volatility, and the contribution of thermal decomposition in the instrument can be identified.

Residential wood combustion emits large amounts of organic compounds, which are transformed in the atmosphere via photochemical ageing reactions. We assessed this organic emission at various stages of exposure with an oxidation flow reactor. Ageing led to major changes in both gaseous and particulate phases including increased acidic compounds and transformation of the polycyclic aromatic compounds. Such changes have serious implications for the health- and climate-related effects of combustion.

Organic aerosol is ubiquitous in the atmosphere and can change its phase state from liquid to solid in response to temperature. Our laboratory measurements demonstrate that the chemical reactivity of typical organic aerosol species with atmospheric oxidants is modulated by the species’ phase state. We find that under temperatures typical of the middle and upper troposphere the chemical lifetime of organic aerosol can be significantly extended due to the reduced reactive uptake of gas oxidants.

Chamber experiments were conducted with alpha-pinene and chlorine under low- and high-nitrogen-oxide (NOX) conditions. We estimated the HOM yields from chlorine-initiated oxidation of alpha-pinene under low-NOX conditions to be around 1.8 %, though with a uncertainty range (0.8 %–4 %) due to lack of suitable calibration methods. Our study clearly demonstrates that the chlorine-atom-initiated oxidation of alpha-pinene can produce low-volatility organic compounds.

EEM–PARAFAC showed a predominant decomposition of protein-like substances and a gradual increase proportion of humic-like substances for BB BrC during O3 aging. The dynamic spectral behavior of chromophores and functional groups within BrC was further explored by 2D-COS.

Emissions of volatile organic compounds (VOCs) from plants are important for tropospheric ozone and secondary organic aerosol (SOA) formation. Real plant emissions are much more diverse than the few proxies widely used for studies of plant SOA. Here we present the first study of SOA from California Sage plants and oxygenated monoterpenes representing their major emissions. We identify SOA products and show the importance of formation of highly oxygenated organic molecules (HOM) and oligomers.

We report on LLPS of organic aerosol consisting of α-pinene- and β-caryophyllene-derived ozonolysis products and commercial organic compounds. Our results show that as compositional complexity increased from one to two organic species, LLPS occurred over a wider range of average O : C values of organic materials (increasing from 0.44 to 0.67). These results provide further evidence that LLPS is likely a frequent occurrence in OA particles in the troposphere, even in the absence of inorganic salt.

Atmospheric particles, a complex mixture of inorganic salts, organic compounds and water, can continually undergo heterogeneous oxidation initiated by gas-phase oxidants at the particle surface. We found that ammonium sulfate can decelerate the rate of heterogeneous OH reaction with 2-methyltetrols when the inorganic-to-organic mass ratio increases. These results would suggest 2-methyltetrols are likely chemically stable against heterogeneous OH oxidation in the atmosphere.

Our results highlight the contribution of gasoline-direct-injection (GDI) vehicles to aerosols, both primary and secondary. The major particles from GDI vehicles are organic and soot particles; they actively participate in chemical conversions in the atmosphere, leading to morphology and composition changes in hours. Rapid ageing could be attributable to the acid-catalysed mechanism and high concentrations of gaseous pollutants. These results would be beneficial for control of PM2.5 pollution.

With experiments performed at CLOUD we show how isoprene interferes in monoterpene oxidation via RO2 termination at atmospherically relevant concentrations. This interference shifts the distribution of Highly Oxygenated organic Molecules (HOMs) away from C20 class dimers towards C15 class dimers, which subsequently reduces both biogenic nucleation and early growth rates. Our results may help to understand the absence of new-particle formation in isoprene rich environments.

We have explored the nature and stability of molecules that give biomass burning smoke its faint brown color. Different types of biomass fuels were burned and the resulting smoke was collected for a detailed chemical analysis. We found that brown molecules in smoke become less colored when they are irradiated by sunlight, but this photobleaching process is very slow. This means that biomass burning smoke will remain brown-colored for a long time and efficiently warm up the atmosphere.

The negative effects of relative humidity (RH) on secondary organic aerosol (SOA) formation from m-xylene under low NOx conditions were observed. The mechanisms of the RH effects of SOA yields have been sufficiently discussed. The decrease of SOA formation at high RH may be mainly attributed to the suppression of oligomers and the further particle-phase reaction of highly oxygenated organic molecules. The faster wall loss of SOA precursors at higher RH may also influence the SOA yield.

Although peat burning is a common global emission source, region-specific emission factors are lacking. This work fills that gap for six peat-bearing regions. It is also shown through simulated aging with an oxidation flow reactor that potential aerosol mass changes during transport.

Refined source apportionment is urgently needed but hard to achieve due to a lack of specific biomarkers. Recently, Fourier transform ion cyclotron resonance mass spectrometry has been used to analyse the probable chemical structure of polar organic matter emitted from off-road engines. We found more condensed aromatic rings in S-containing compounds for HFO-fueled vessels, while more abundant aliphatic chains were observed in emissions from diesel equipment.

In this study, we highlight the potential impact of particles from certain terrestrial sources on the formation of ice crystals in clouds. In particular, we focus on biogenic particles consisting of various organic compounds which makes it very difficult to predict the ice nucleation properties of complex ambient particles. We find that these ambient particles are often more ice-active than individual components.

Wildfires are a large source of gases and particles to the atmosphere, both of which impact human health and climate. The amount and composition of particles from wildfires can change with time in the atmosphere; however, the impact of aging is not well understood. In a series of controlled laboratory experiments, we show that the particles are oxidized and a significant fraction of the gas-phase carbon (24 %–56 %) is converted to particle mass over the course of several days in the atmosphere.

Organic nitrate is ubiquitous in the atmosphere and impacts the formation of aerosol and ozone, two leading air pollutants of concern worldwide. We conducted a comprehensive laboratory study to investigate the hydrolysis process of organic nitrate aerosol formed from monoterpenes, which are important reactive chemicals emitted by plants. Our results provide experimentally constrained parameters required to assess the role of organic nitrate in the formation of the air pollutants of our concern.

Hygroscopicity is one of the most important properties of aerosol particles, and a number of experimental techniques, which differ largely in principles, configurations and cost, have been developed to investigate hygroscopic properties of atmospherically relevant particles. Our paper provides a comprehensive and critical review of available techniques for aerosol hygroscopicity studies.

This study confirmed that SO2 uptake on mineral particles could be greatly enhanced during cloud processing. The large pH fluctuations between the cloud-aerosol modes could significantly modify the microphysical properties of particles, and triggered the formation of reactive Fe particles to accelerate sulfate formation via a self-amplifying process. Results of this study could partly explain the missing source of sulfate and improve agreement between models and field observations.

During atmospheric transport, dissolved organic matter (DOM) within aqueous aerosols undergoes photochemistry. We find that photochemical processing of DOM increases its ability to form cloud droplets but decreases its ability to form ice crystals over a simulated 4.6 days in the atmosphere. A photomineralization mechanism involving the loss of organic carbon and the production of organic acids, CO and CO2 explains the observed changes and affects the liquid-water-to-ice ratio in clouds.

This work provides the first direct field evidence that anthropogenic organo-nitrate contributed up to half of secondary organic aerosol (SOA) mass that was freshly produced within the emission plumes of oil sands facilities in Alberta, Canada. The findings illustrate the central role of organo-nitrate in SOA production from the oil and gas industry, with relevance for other urban and industrial regions with significant intermediate-volatility organic compounds (IVOCs) and NOx emissions.

Box model simulations, based on the volatility basis set approach, of smog chamber wood combustion experiments conducted at different temperatures (−10 °C, 2 °C, 15 °C), emission loads, combustion conditions (flaming and smoldering) and residential stoves fabricated in the last 2 decades. Novel parameterization methods based on a genetic algorithm approach allowed estimation of precursor class contributions to SOA and evaluation of the effect of emission variability on SOA yield predictions.

Oxidation of bromide and iodide is an important process in the troposphere that leads to gas-phase halogen compounds which impact the oxidation capacity of the atmosphere. Imidazole-2-carboxaldehyde (IC), an aromatic carbonyl, is a product of the multiphase chemistry of glyoxal (an oxidation product of isoprene), a major biogenic volatile organic compound. In this study we demonstrate that IC photochemistry leads to efficient oxidation of bromide and iodide and liberation of halogen compounds.

We measured the diffusion rates of organic molecules in a number of proxies for secondary organic aerosol (SOA) and compared measured diffusion with predictions from two relations: the Stokes–Einstein relation and a fractional Stokes–Einstein relation. The fractional relation does a better job of predicting diffusion rates in this case. Output from an atmospheric model shows that mixing times predicted using the two relations differ by up to 1 order of magnitude at an altitude of ~ 3 km.

Short summary
Native to Australasia, the remarkable adaptability, rapid growth rates and high quality wood of eucalypt trees has led to them the most widely planted hardwood forest trees in the world. In contrast to boreal and tropical forests, there has been little study of aerosol formation in these regions. Here, we study the secondary organic aerosol formation from the very fast reaction of α-phellandrene, emitted from eucalypts, and identify key products and reaction pathways.
