Short summary
Biogenic volatile organic compounds are intensely emitted by forests and crops and react with the nitrate radical during the nighttime to form functionalized products. The purpose of this study is to furnish kinetic and mechanistic data for terpinolene and β-caryophyllene, using simulation chamber experiments. Rate constants have been measured using both relative and absolute methods, and mechanistic studies have been conducted in order to identify and quantify the main reaction products.

We test the hypothesis that significant secondary organic aerosol production can take place even during winter nights through the oxidation of the emitted organic vapors by the nitrate radicals produced during the reaction of ozone and nitrogen oxides. Our experiments, using as a starting point the ambient air of an urban area with high biomass burning activity, demonstrate that, even with sunlight, there is 20 %–70 % additional organic aerosol formed in a few hours.

An incoherent broadband cavity-enhanced absorption spectroscopy (IBBCEAS) technique has been developed for the in situ monitoring of NO3 radicals in the CSA simulation chamber at LISA. The optical cavity allows a high sensitivity for NO3 detection up to 6 ppt for an integration time of 10 s. The technique is now fully operational and can be used to determine rate constants for fast reactions involving complex volatile organic compounds (with rate constants up to 10−10 cm3 molecule−1 s−1).

The gas-phase reactions of organic compounds in the atmosphere are a crucial step in the degradation of anthropogenic and biogenic emissions and the formation of secondary pollutants. This work is an attempt to produce a dataset that is as comprehensive as possible regarding the multitude of chemicals that react in the atmosphere. We find that we are able to make substantial improvements upon previous compendia and that this progress will help improve our understanding of atmospheric chemistry.

HONO and NO2 play a crucial role in the atmospheric oxidation capacity that affects the regional air quality and global climate. Accurate measurements of HONO are challenging due to the drawback of existing detection methods. Calibration-free high-sensitivity direct, simultaneous measurements of NO2, HONO and CH2O with UV-IBBCEAS provide accurate and fast quantitative analysis of their concentration variation within their lifetime by intercomparison with NOx, FTIR and NitroMAC sensors.

The chemical composition of aerosol particles is very important as it determines to which extent they can affect the Earth's climate by acting with solar light and modifying the properties of clouds. The South Atlantic region is a remote and under-explored region to date where these effects could be important. The measurements presented in this paper consist in the analysis of samples collected at a coastal site in Namibia. The first long-term source apportionment is presented and discussed.

We showed that Icelandic dust has a fundamentally different chemical and mineralogical composition from low-latitude dust. In particular, magnetite is as high as 1 %–2 % of the total dust mass. Our results suggest that Icelandic dust may have an important impact on the radiation balance in the subpolar and polar regions.

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.

This paper presents a new dataset of laboratory measurements of the shortwave (SW) spectral complex refractive index and single-scattering albedo (SSA) for global mineral dust aerosols of varying origin and composition. Our results show that the dust refractive index and SSA vary strongly from source to source, mostly due to particle iron content changes. We recommend that source-dependent values of the SW spectral refractive index and SSA be used in models and remote sensing applications.

Evolution of the vertical distribution and optical properties of aerosols in the free troposphere is analysed for the first time over the Namibian coast, a region where uncertainties on aerosol–cloud coupling in climate simulations are significant. The high variability of atmospheric aerosol composition is highlighted using a combination of ground-based, airborne and space-borne lidar. Aerosols are mainly transported from Angola, but part of the highest aerosol layer may come from South America.

We present findings from a summertime field campaign at the remote island of Lampedusa in the central Mediterranean Sea. We show that the aerosol loading is similar to coastal sites around the Mediterranean. We observe higher loadings of sulfate and aged organic aerosol from air masses transported over the central and eastern Mediterranean in comparison to those from the western Mediterranean. These results highlight the rarity of pristine air masses, even in remote marine environments.

Three-years of continuous measurements at the Henties Bay Aerosol Observatory (HBAO; 22°S, 14°05’E), Namibia, show that during the austral wintertime, long- and medium-range transport of pollution from biomass and fossil fuel burning give rise to peaks of light-absorbing black carbon aerosols into the marine boundary layer ahead of the main biomass burning season. This could affect the cloud properties.

Mineral dust is one of the most abundant aerosol species at the global scale and an accurate estimation of its absorption at solar wavelengths is crucial to assess its impact on climate. In this work we provide an estimate of the Aethalometer multiple scattering correction for mineral dust aerosols at 450 and 660 nm. Our results suggest that the use of an optimized correction factor can lead to up to 11 % higher absorption coefficient and to 3 % higher single scattering albedo for mineral dust.

This paper presents new laboratory measurements of the shortwave mass absorption efficiency (MAE) used by climate models for mineral dust of different origin and at different sizes. We found that small particles are more efficient, by given mass, in absorbing radiation, particularly at shorter wavelength. Because dust has high concentrations in the atmosphere, light absorption by mineral dust can be competitive to other absorbing atmospheric aerosols such as black and brown carbon.

Modeling the interaction of dust with long-wave (LW) radiation is still a challenge due to the scarcity of information on their refractive index. In this paper, we present a unique dataset of dust refractive indices obtained from in situ measurements in a large smog chamber. Our results show that the dust LW refractive index varies strongly from source to source due to particle composition changes. We recommend taking this variability into account in climate and remote sensing applications.

The impact of cloud events on isoprene secondary organic aerosol (SOA) formation has been studied from an isoprene/ NOx/light system in an atmospheric simulation chamber. aqSOA formation can be linked to water soluble volatile organic compounds' dissolution in the aqueous phase and to further aqueous phase reactions. Cloud-induced SOA formation is experimentally demonstrated in this study, thus highlighting the importance of aqueous multiphase systems in atmospheric SOA formation estimations.

We studied the impact of aerosols on tropospheric photolysis rates at Lampedusa during the CharMEx/ADRIMED campaign in June 2013. It is shown by using the CHIMERE chemistry-transport model (CTM) as well as in situ and remote-sensing measurements that taking into account the radiative effect of the tropospheric aerosols improves the ability of the model to reproduce the observed photolysis rates. It is hence important for CTMs to include the radiative effect of aerosols on photochemistry.

The aim of this article is to present an experimental campaign over the Mediterranean focused on aerosol-radiation measurements and modeling. Results indicate an important atmospheric loading associated with a moderate absorbing ability of mineral dust. Observations suggest a complex vertical structure and size distributions characterized by large aerosols within dust plumes. The radiative effect is highly variable, with negative forcing over the Mediterranean and positive over northern Africa.

First- and higher order -generation products formed from the oxidation of isoprene and methacrolein with OH radicals in the presence of NOx have been studied in a simulation chamber. Differences in light source are proposed to partially explain the discrepancies observed between different studies in the literature for both isoprene- and methacrolein-SOA mass yields. According to our results, these SOA yields in the atmosphere could be lower than suggested by most of the current chamber studies.

The reaction between OH and SO2 is a termolecular process that in the atmosphere results in the formation of H2SO4 and thus aerosols. We present the first temperature- and pressure-dependent measurements of the rate coefficients in N2. This is also the first study to examine the effects of water vapour on the kinetics of this reaction. Our results indicate the rate coefficient is larger than that recommended by evaluation panels, with deviations of up to 30 % in some parts of the atmosphere.

Heterogeneous oxidation of SO2 is suggested to be one of the most important pathways for sulfate formation during extreme haze events in China, yet the exact mechanism remains highly uncertain.

Landscape fires are a major source of greenhouse gases and aerosols, particularly in sub-tropical savannas. Stable carbon isotopes in emissions can be used to trace the contribution of C3 plants (e.g. trees or shrubs) and C4 plants (e.g. savanna grasses) to greenhouse gases and aerosols if the process is well understood. This helps us to link individual vegetation types to emissions, identify biomass burning emissions in the atmosphere, and improve the reconstruction of historic fire regimes.

The diurnal atmospheric degradation of 2-methylbutanal, 2 MB, emitted by sources like vegetation or the poultry industry is evaluated in this work. Sunlight and oxidants like hydroxyl (OH) radicals and chlorine (Cl) atoms initiate this degradation. Measurements of how fast 2 MB is degraded and what products are generated are presented. The lifetime of 2 MB is around 1 h at noon, when the OH reaction dominates. Thus, 2 MB will not be transported far, affecting only local air quality.

Gas-phase reaction rate coefficients of OH radicals with four nitrocatechols have been investigated for the first time by using ESC-Q-UAIC chamber facilities. The reactivity of all investigated nitrocatechols is influenced by the formation of the intramolecular H-bonds that are connected to the deactivating electromeric effect of the NO2 group. For the 3-nitrocatechol compounds, the electromeric effect of the
freeOH group is diminished by the deactivating E-effect of the NO2 group.

Every spring in the Arctic, a series of photochemical events occur over the ice-covered ocean, known as bromine explosion events, ozone depletion events, and mercury depletion events. Here we report the re-creation of these events at an outdoor sea ice facility in Winnipeg, Canada, far away from the Arctic. The success provides a new platform with new opportunities to uncover fundamental mechanisms of these Arctic springtime phenomena and how they may change in a changing climate.

Wildfires are increasing in extent and severity, driven by climate change. Such fires emit large amounts of volatile organic compounds (VOCs) to the atmosphere. Many of these, such as the furans studied here, are very reactive and are rapidly converted to other VOCs, which are expected to have negative health effects and to further impact the climate. Here, we establish the importance of the nitrate radical for removing these compounds both during the night and during the day.

We performed chamber experiments to measure the composition of the gas phase reaction products of nitrate radical initiated oxidation of four monoterpenes. Total organic yield, effective oxygen-to-carbon ratio, and dimer-to-monomer ratio correlated with observed particle formation for the monoterpene systems with some exceptions. The d-carene system produced the most particles, followed by b-pinene, with the a-pinene and a-thujene systems producing no particles.

Understanding the chemistry of biomass burning plumes is of global interest. Within this work we investigated the OH radical reaction of 3-penten-2-one, which has been identified in biomass burning emissions. We observed the primary formation of peroxyacetyl nitrate (PAN), a key NOx reservoir species. Besides, PAN precursors were also identified as main oxidation products. 3-Penten-2-one is shown to be an example explaining rapid PAN formation within young biomass burning plumes.

This work explores the kinetics and reactivity of epoxides towards the OH radical using two different simulation chambers. Estimation of the rate coefficients has also been made using different structure-activity relationship (SAR) approaches.

The photo-oxidation of myrcene, a monoterpene species emitted by plants, was investigated at atmospheric conditions in the outdoor simulation chamber SAPHIR.

This study measured 106 VOC species using a GC-MS/FID. Meanwhile, the WRF-CMAQ model was used to investigate the nonlinearity of the O3 response to precursor reductions. This study highlights the effectiveness of stringent emission controls in relation to solvent utilization and coal combustion. However, unreasonable emission reduction may aggravate ozone pollution during control periods. It is suggested that emission-reduction ratios of the precursors (VOC : NOx) should be more than 2.

Within this work we determined the rate coefficients and products of the reaction of unsaturated ketones with OH radicals in an effort to complete the gaps in the knowledge needed for modelling chemistry in the atmosphere. Both substances are potentially emitted by biomass burning, industrial activities or formed in the troposphere by oxidation of terpenes. As products we identified aldehydes and ketones which in turn are known to be responsible for the transportation of NOx species.

Isoprene is the biogenic volatile organic compound with the largest emissions rates. The nighttime reaction of isoprene with the NO3 radical has a large potential to contribute to SOA. We classified isoprene nitrates into generations and proposed formation pathways. Considering the potential functionalization of the isoprene nitrates we propose that mainly isoprene dimers contribute to SOA formation from the isoprene NO3 reactions with at least a 5 % mass yield.

The reaction of isoprene, a biogenic volatile organic compound with the globally largest emission rates, with NO3, an nighttime oxidant influenced heavily by anthropogenic emissions, forms a large number of highly oxygenated organic molecules (HOM). These HOM are formed via one or multiple oxidation steps, followed by autoxidation. Their total yield is much higher than that in the daytime oxidation of isoprene. They may play an important role in nighttime organic aerosol formation and growth.

A significant fraction of emissions from human activity consists of aromatic hydrocarbons, e.g. benzene, which oxidise to form new compounds important for particle growth. Characterisation of benzene oxidation products highlights the range of species produced as well as their chemical properties and contextualises them within relevant frameworks, e.g. MCM. Cluster analysis of the oxidation product time series distinguishes behaviours of CHON compounds that could aid in identifying functionality.

Biomass burning is a major source of trace gases to the troposphere; however, the composition and quantity of emissions vary greatly between different fuel types. This work provided near-total quantitation of non-methane volatile organic compounds from combustion of biofuels from India. Emissions from cow dung cake combustion were significantly larger than conventional fuelwood combustion, potentially indicating that this source has a disproportionately large impact on regional air quality.

The photooxidation of pinonaldehyde is investigated in a chamber study under natural sunlight and low NO conditions with and without an added hydroxyl radical (OH) scavenger. The experimentally determined pinonaldehyde photolysis frequency is faster by a factor of 3.5 than currently used parameterizations in atmospheric models. Yields of degradation products are measured in the presence and absence of OH. Measurements are compared to current atmospheric models and a theory-based mechanism.

Earth’s snow cover is very dynamic and can change its physical properties within hours, as is well known by skiers. Snow is also a well-known host of chemical reactions – the products of which impact air composition and quality. Here, we present laboratory experiments that show how the dynamics of snow make snow essentially inert with respect to gas-phase ozone with time despite its content of reactive chemicals. Impacts on polar atmospheric chemistry are discussed.

We conducted a series of experiments in which the 185 to 254 nm photon flux ratio (I185 : I254) emitted by low-pressure mercury lamps installed in an oxidation flow reactor (OFR) was systematically varied using multiple novel lamp configurations. Integrated OH exposure values achieved for each lamp type were obtained as a function of OFR operating conditions. A photochemical box model was used to develop a generalized OH exposure estimation equation as a function of [H2O], [O3], and OH reactivity.

Dimethyl sulfide (DMS) is the major sulfur-containing species in the troposphere. Previous work by Newland et al. (2015) reported very high reactivity of isoprene-derived Criegee intermediates (CIs) towards DMS. By monitoring CIs with direct UV absorption, we found CI + DMS reactions are very slow, in contrast to the results of Newland et al. (2015), suggesting these CIs would not oxidize atmospheric DMS at any substantial level.

Iodine-bearing gasses emitted from the sea surface are chemically processed in the atmosphere, leading to iodine accumulation in aerosol and transport to continental ecosystems. Such processing involves light-induced break-up of large, particle-forming iodine oxides into smaller, ozone-depleting molecules. We combine experiments and theory to report the photolysis efficiency of iodine oxides required to assess the impact of iodine on ozone depletion and particle formation.

We present direct measurements of NO3 reactivity resulting from the oxidation of isoprene by NO3 during an intensive simulation chamber study. Measurements were in excellent agreement with values calculated from measured isoprene amounts and the rate coefficient for the reaction of NO3 with isoprene. Comparison of the measurement with NO3 reactivities from non-steady-state and model calculations suggests that isoprene-derived RO2 and HO2 radicals account to ~ 50 % of overall NO3 losses.

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.

Environmental chamber studies were performed to evaluate atmospheric degradation initiated by OH radicals for two unsaturated methoxy ketones. The main gas-phase oxidation products identified and quantified from these reactions are carbonyls and long-lived nitrogen-containing compounds such as peroxyacetyl nitrate and peroxypropionyl nitrate. The kinetic rate constants and atmospheric lifetimes were estimated, degradation mechanisms were developed, and atmospheric implications were assessed.

We measured total reactive nitrogen, Nr, in lab fires from western North American fuels, along with measurements of individual nitrogen compounds. We measured the amount of N that gets converted to inactive compounds (avg. 70 %), and the amount that is accounted for by individual species (85 % of remaining N). We provide guidelines for how the reactive nitrogen is distributed among individual compounds such as NOx and ammonia. This will help estimates and predictions of wildfire emissions.

We have determined the rate coefficient and mechanism for the reaction of the OH radical with methane sulphonamide, a trace gas which has recently been found in the atmosphere. The rate coefficient is 1.4 × 10−13 cm3 molec.−1 s−1, which indicates a tropospheric lifetime of > 2 months. The observation of CO, CO2, SO2, HNO3, HCOOH, and N2O products enabled us to derive a detailed reaction mechanism for the reaction, which proceeds predominantly by H abstraction from the CH3 group.

Oxidation chemistry of organic compounds in the atmosphere produces a diverse spectrum of products. This diversity is difficult to represent in air quality and climate models, and in laboratory experiments it results in large and complex datasets. This work evaluates several methods to simplify the chemistry of oxidation systems in environmental chambers, including positive matrix factorization, hierarchical clustering analysis, and gamma kinetics parameterization.

Saturated alcohols (SAs), such as (E)-4-methylcyclohexanol, 3,3-dimethyl-1-butanol, and 3,3-dimethyl-2-butanol, could be used as biofuels.

The experimental results obtained in this work reveal that uncontrolled emissions of these saturated alcohols could have important atmospheric implications.

Highly oxygenated organic molecules (HOMs) facilitate aerosol formation in the atmosphere. Using NO3− chemical ionization mass spectrometry we investigated HOM composition and yield in oxidation of aromatic compounds at different reactant concentrations, in the presence of NOx and seed aerosol. Higher OH concentrations increased HOM yield, suggesting multiple oxidation steps, and affected HOM composition, potentially explaining in part discrepancies in published secondary organic aerosol yields.

We present, for the first time, the dual effect of GDI-vehicle exhaust on α-pinene SOA mass yield suppression. The first effect is a well-known NOx effect, but the second effect is more complex. Our results imply that this second effect is related to change of reaction pathways of α-pinene in the presence of GDI exhaust. The presence of vehicle exhaust caused more than 50 % suppression in α-pinene SOA mass yield compared to the α-pinene SOA mass yield measured in the absence of GDI emissions.

The role of anthropogenic VOCs (AVOCs) for SOA formation needs to be scrutinised. The aromatic 1,3,5-trimethylbenzene (TMB) was shown to form highly oxygenated organic molecules (HOMs) in NOx-free environments, possibly contributing to new particle formation (NPF). However, formation of HOMs and particles was suppressed in the presence of NOx, while the formation of organonitrates (ONs) was increased. Thus, aromatic AVOCs may not enhance NPF in urban air masses.

Aromatic hydrocarbons contribute significantly to the production of tropospheric ozone and secondary organic aerosol (SOA). Here later-generation low-volatility oxygenated products from toluene and 1,2,4-TMB oxidation by OH are detected in the gas and particle phases. We show that these products, previously identified as highly oxygenated molecules (HOMs), are formed in more than one pathway with differing numbers of reaction steps with OH. They also make up a significant fraction of SOA.

Atmospheric furan is a primary and secondary pollutant in the atmosphere, and its emission contributes to the formation of ultrafine particles and ground-level ozone. The present study demonstrates the effect of NOx and humidity on secondary organic aerosol (SOA) formation during the furan–NOx–NaCl photooxidation. Furthermore, the results illustrate the importance of studying SOA formation over a comprehensive range of environmental conditions.

Short summary
Multifunctional organic nitrates are important atmospheric species that are known to play a key role in the transport of reactive nitrogen and in aerosol composition. However, very little is known about their atmospheric reactivity. Here we provide an experimental study on the photolysis and reaction of two carbonyl nitrates with OH radicals. Atmospheric implications and the influence of the chemical structure on the reactivity are discussed.
