Brown carbon (BrC) aerosol can be produced by the smoldering combustion of peat, a wildland fuel common at high latitude, often adjacent to the cryosphere. However, little is known about how BrC deposition onto snow changes snow optical and radiative properties. Here, we artificially deposited BrC onto natural snow surfaces, monitored changes of the spectral surface albedo, characterized optical properties of deposited aerosol, and compared to modeled values of albedo and radiative forcing.

Optical properties of polar and non-polar extracts of biomass burning organic aerosols (BBOAs) generated by burning of globally and regionally important fuels were studied. The non-polar fraction of BBOAs was found to be more light absorbing than the polar fraction. Laboratory aging of BBOAs produced by flaming fuels increased aerosol light absorption attributed to the formation of organo-nitrogen compounds. Refractive indices were retrieved for both polar and non-polar extracts of BBOAs.

This paper introduces a retrieval algorithm to estimate two key absorbing components in smoke (black carbon and brown carbon) using DSCOVR EPIC measurements. Our analysis reveals distinct smoke properties, including spectral absorption, layer height, and black carbon and brown carbon, over North America and central Africa. The retrieved smoke properties offer valuable observational constraints for modeling radiative forcing and informing health-related studies.

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.

Source profiles that allow peat fire contributions to be distinguished from other source contributions using receptor models are lacking for a wide variety of peat fuels and burning conditions. These profiles change with photochemical aging during transport. Fresh and aged profiles for a variety of peat fuels are measured with an oxidation flow reactor to improve source attributions at distant receptors.

Particulate matter found in the atmosphere, or aerosols, can deposit on snow and ice and significantly change its reflectivity. Consequently, the timing of snow melt and snow water runoff is also changed. To study these processes, it is important to be able to deposit aerosols in a controlled manner on snow surfaces. Here, we present the design and demonstrate the use of an apparatus for deposition of common mineral dust and combustion aerosols.

We present spatial measurements of particle volatility and mixing state near a US interstate highway. We find that the relative abundance of semi-volatile species in ultrafine particles decreases with downwind distance and the mixing state of roadside aerosols does not change significantly within a few hundred meters from the highway. The results from our study show that exposures and impacts of near-road particles may differ across seasons and under changing ambient conditions.

Black carbon measurements are usually conducted with absorption filter photometers, which are prone to the filter-loading effect – a saturation of the instrumental response due to the accumulation of the sample in the filter matrix. In this paper, we conducted several field campaigns to investigate the hypothesis that this filter-loading effect depends on the optical properties of particles present in the filter matrix, especially on the coating of black carbon particles.

The impacts of aerosols on health, visibility, and climate are very sensitive to their ability to take up water under subsaturated conditions and to serve as cloud condensation nuclei. These hydration properties are tightly linked to aerosol composition. This report finds that water soluble organic compounds contribute significantly to atmospheric aerosol hydration both as an independent fraction of aerosol mass and through complementary interactions with common inorganic aerosol constituents.

This laboratory study was performed on re-suspended dust samples collected from several known dust sources of the world. We measured dust by multiple analytical techniques to understand their physical and chemical characteristics. Studies of the properties of dust are necessary to assess the magnitude of the growing dust problem, identify sources of dust, and, where feasible, apply preventative measures and remediation practices. Results can be used in global climate and health studies.

Short summary
Brown carbon aerosols dominate particulate emissions from the burning of Alaskan and Siberian peatlands. They physically occur as amorphous "tar balls" with negligible black carbon mixing. They absorb very strongly in the shorter visible wavelengths, characterized by a mean Ångström coefficient of ≈ 9. These aerosols could result in a net warming of the atmosphere, provided the albedo of the underlying surface is greater than 0.6.

Lignin and Snomax are surface-active macromolecules that show a relationship between increasing concentrations, decreasing surface tension, and increasing ice-nucleating ability. However, this relationship did not hold for agricultural soil extracts collected in the UK and Canada. To explain this difference, we propose that as the complexity of the sample increases, the hydrophobic interfaces in the bulk compete with the air–water interface.

This work provides the first fundamental laboratory data to evaluate SOA (secondary organic aerosol) production from styrene and NO3 chemistry. Additionally, the formation mechanisms of aromatic organic nitrates (ONs) are reported, highlighting that previously identified nitroaromatics in ambient field campaigns can be aromatic ONs. Finally, the hydrolysis lifetimes observed for ONs generated from styrene and NO3 oxidation can serve as experimentally constrained parameters for modeling hydrolysis of aromatic ONs in general.

Hydrogen peroxide (HOOH) is an important oxidant that forms atmospheric sulfate. We demonstrate that the illumination of brown carbon can rapidly form HOOH within particles, even under the low-sunlight conditions of Fairbanks, Alaska, during winter. This in-particle formation of HOOH is fast enough that it forms sulfate at significant rates. In contrast, the formation of HOOH in the gas phase during the campaign is expected to be negligible because of high NOx levels.

The chemical composition of organic aerosol derived from wood-burning emissions under different burning conditions was characterised. Fresh emissions from flaming and smouldering were largely aromatic in nature, whereas upon aging the aromatic content decreased. This decrease was greater for smouldering due to the loss of toxic polyaromatic species, whereas under flaming conditions highly toxic polyaromatic species were produced. These differences present an important challenge for future policy.

Halogenated polycyclic aromatic hydrocarbons (XPAHs) are emerging pollutants. Stability during atmospheric transformation processes is crucial for predicting their environmental fate and assessing the associated risks. Here, we conducted field studies and laboratory simulation experiments to reveal the mechanisms, influencing factors and products for XPAHs' heterogeneous phototransformation. Results revealed that the conversion of XPAHs led to a reduction in environmental risk.

The initiation of autoxidation by ozonolysis was investigated on levitated linoleic acid droplets using electrodynamic balance–mass spectrometry. Exposing the droplets to ozone for one hour before switching the gas phase to air without ozone led to a shortening of the autoxidation initiation phase in comparison to experiments without ozone exposure. Results were compared to a bulk reaction model to investigate the synergistic effects of ozonolysis and autoxidation.

The assessment of chromium occurrence in particulate matter in cities: PM10, PM2.5, PM1 and PM0.25 during the calendar year was presented. The seasonality of both pseudototal chromium content and its valence speciation was examined. Seasonality of changes in Crtot and Cr(VI) concentrations was observed. Maximum in the winter season, most likely due to the greater share of fuel combustion sources. Regardless of the season, the risk levels for Radom residents were within the acceptable risk range.

Understanding the surface composition of aerosols is crucial for advancing climate models. We investigated the interface of single-component and mixed aqueous solutions of atmospherically relevant carboxylic acid and alkyl-ammonium ions using liquid-jet photoelectron spectroscopy. An exponential increase in surface propensity as a function of chain length was found for the single species, and cooperative effects in the mixtures cause a further drastic increase in surface solute concentration.

This article comprehensively investigates the aqueous-phase OH oxidation of benzothiazoles (BTs), common rubber additives found in urban air, through laboratory simulation experiments. BTs can rapidly degrade, leading to light absorption, high yields of sulfate, and the formation of highly oxidized and/or oligomerized organic compounds. The results reveal that aqueous-phase BTs can contribute to secondary aerosols, altering the chemical and optical properties of atmospheric particles.

This study investigated the evolution of biomass and coal combustion-derived WSOM during aqueous photochemical process. The results indicate that photochemical aging induces distinct changes in the optical and molecular properties of WSOM and more pronounced alterations were observed during ·OH photooxidation than direct photolysis. Notably, our results also demostrated that atmospheric photooxidation may represent a significant source of BC-like substances.

We investigated the aqueous nitrate-mediated photooxidation of four green leaf volatiles (GLVs). The aqueous reaction medium conditions, dilute cloud/fog vs. concentrated aqueous aerosol conditions, governed the effects that pH, ionic strength, and sulfate have on the GLV degradation rates and aqSOA mass yields. Most notably, reactions initiated by sulfate photolysis have significant effects in aqueous aerosols, but not in cloud/fog droplets.

Thin film formation at the air–water interface from material extracted from atmospheric aerosol was demonstrated, supporting the core–shell morphology. Film thicknesses were approximately 10 Å and 17 Å for urban and remote extracts, respectively. Exposure to gas-phase OH radicals showed fast reactions and short lifetimes of around 1 h. The effect on the Earth's radiative balance indicated that removing half of the film could significantly increase the top-of-atmosphere albedo for urban films.

Air pollution and climate change are influenced by tiny airborne particles called aerosols. This study explores how pollutants from urban sources, as m-xylene and naphthalene, form new particles in the atmosphere under different conditions. Using advanced techniques, we show how temperature and nitrogen oxides affect the formation and behaviour of these particles. Our findings will improve our understanding on secondary organic particle and air quality models.

High-latitude cities like Fairbanks, Alaska, experience severe wintertime pollution episodes. While conventional wisdom holds that oxidation is slow under these conditions, field measurements find oxidized products in particles. To explore this, we measured oxidants in aqueous extracts of winter particles from Fairbanks. We find high concentrations of oxidants during illumination, indicating that particle photochemistry can be significant even in high latitudes during winter.

The metabolic capacity of atmospheric microorganisms after settling into habitats is poorly understood. We studied the molecular composition of exometabolites for cultured typical airborne microbes and traced their metabolic processes. Bacteria and fungi produce highly oxidized exometabolites and have significant variations in metabolism among different strains. These insights are pivotal for assessing the biogeochemical impacts of atmospheric microorganisms following their deposition.

Under dry conditions the reaction does not proceed to completion, while under high humidity conditions the reactivity proceeds further. These results indicate the reactivity with ozone is likely impacted by aerosol phase state (e.g. aerosol viscosity).

Past atmospheric NH3 pollution in south-eastern Europe was reconstructed by analysing ammonium in an ice core drilled at the Mount Elbrus (Caucasus, Russia). The observed 3.5-fold increase in ice concentrations between 1750 and 1990 CE is in good agreement with estimated past dominant ammonia emissions from agriculture, mainly from south European Russia and Türkiye. In contrast to present-day conditions, the ammonium level observed in 1750 CE indicates significant natural emissions at that time.

Recent research has established the contribution of 1,3-butadiene (13BD) to organic aerosol formation with negative implications for urban air quality. Health effect studies have focused on whole particulate matter, but compounds responsible for adverse health effects remain uncertain. This study provides the effect of relative humidity and seed aerosol acidity on the chemical composition of aerosol formed from 13BD photooxidation.

Photochemical reactions altered the properties of kerosene-operated jet engine burner exhaust emissions, which were studied in laboratory using an oxidation flow reactor. Particle mass increased 300-fold as particles and gases became more oxidized. Light absorption increased, but the total direct radiative forcing efficiency was estimated to shift from positive to negative. The results highlight the importance of considering secondary aerosol formation when assessing the impacts of aviation.

Secondary organic aerosols (SOAs) from acetone photooxidation in the presence of various seeds were studied to illustrate SOA formation kinetics under ammonia-rich conditions. The oxidation mechanism of acetone was investigated using an observation-based model incorporating a Master Chemical Mechanism model. A higher SOA yield of acetone was observed compared to methylglyoxal due to an enhanced uptake of the small photooxidation products of acetone.

We followed nano-structural changes in mixtures found in urban organic aerosol emissions (oleic acid, sodium oleate and fructose) during humidity change and ozone exposure. We demonstrate that self-assembly of fatty acid nanostructures can impact water uptake and chemical reactivity, affecting atmospheric lifetimes, urban air quality (preventing harmful emissions from degradation and enabling their long-range transport) and climate (affecting cloud formation), with implications for human health.

We developed a continuous flow analysis system to analyze an ice core from northwestern Greenland and coupled it with an improved refractory black carbon (rBC) measurement technique. This allowed accurate high-resolution analyses of size distributions and concentrations of rBC particles with diameters of 70 nm–4 μm for the past 350 years. Our results provide crucial insights into rBC's climatic effects. We also found previous ice core studies substantially underestimated rBC mass concentrations.

Aerosol particles composed of metal complexes generate radicals as the result of photochemical reactions. Reactive species generated are hazardous to human health. We report microscopy data with particles composed of an organic proxy exposed to UV light. We found that copper influenced the reoxidation and initial iron reduction via photolysis of the complex. New model results suggest that we need to account a decreased photochemical activity and use a copper-induced reoxidation reaction.

Atmospheric secondary aerosols, composed of organic and inorganic components, undergo complex reactions that impact their phase state. Using molecular spectroscopy, we showed that ammonium-promoted aqueous replacement reaction, unique to these aerosols, is closely linked to phase behavior. The interplay between reactions and aerosol phase state can cause atypical phase transition and irreversible changes in aerosol composition during hygroscopic cycles, further impacting atmospheric processes.

Single-particle mass spectrometry (SPMS) is commonly used to measure the chemical composition and mixing state of aerosol particles. Intercomparison of SPMS instruments was conducted. All instruments reported similar size ranges and common spectral features. The instrument-specific detection efficiency was found to be more dependent on particle size than type. All differentiated secondary organic aerosol, soot, and soil dust but had difficulties differentiating among minerals and dusts.

We found two different playa lakes according to the groundwater regime, which implies differences in crusts' cohesion state and mineralogy, which can affect the dust emission potential and properties. We also compare them with Moroccan Sahara crusts and Icelandic top sediments.

The present research unveiled that acidity dominates while transition metal ions harmonize with the light absorption properties of humic-like substances (HULIS). Cu2+ has quenching effects on HULIS by complexation, hydrogen substitution, or electrostatic adsorption, with aromatic structures of HULIS. Such effects are less pronounced if from Mn2+, Ni2+, Zn2+, and Cu2+. Oxidized HULIS might contain electron-donating groups, whereas N-containing compounds might contain electron-withdrawing groups.

We provide evidence that light enhances the conversion of SO2 to sulfates on non-photoactive mineral dust, where triplet states of SO2 (3SO2) can act as a pivotal trigger to generate sulfates. Photochemical sulfate formation depends on H2O, O2, and basicity of mineral dust. The SO2 photochemistry on non-photoactive mineral dust contributes to sulfates, highlighting previously unknown pathways to better explain the missing sources of atmospheric sulfates.

The unique formulas of coal combustion aerosols were characterized by higher unsaturated compounds, and such information could be used for source appointment.

The parameterized k2–T relationships and observed surface temperature data were used to estimate the chemical lifetimes of COA particles.

We measured changes in light absorption during the aqueous oxidation of six phenols with hydroxyl radical (●OH) or an organic triplet excited state (3C*). All the phenols formed light-absorbing secondary brown carbon (BrC), which then decayed with continued oxidation. Extrapolation to ambient conditions suggest ●OH is the dominant sink of secondary phenolic BrC in fog/cloud drops, while 3C* controls the lifetime of this light absorption in particle water.

We developed a method that uses aqueous S(IV) to quantitatively convert NO2 to NO2−, which allows both species to be quantified using the Griess method. As an example of the utility of the method, we quantified both photolysis channels of nitrate, with and without a scavenger for hydroxyl radical (·OH). The results show that without a scavenger, ·OH reacts with nitrite to form nitrogen dioxide, suppressing the apparent quantum yield of NO2− and enhancing that of NO2.

In this study we examined the effect of atmospheric aging on sea spray aerosols (SSAs) to form ice and how newly formed secondary marine aerosols (SMAs) may freeze at cirrus temperatures (< −38 °C). Results show that SSAs freeze at different relative humidities (RHs) depending on the temperature and that the ice-nucleating ability of SSA was not hindered by atmospheric aging. SMAs are shown to freeze at high RHs and are likely inefficient at forming ice at cirrus temperatures.

We studied reactions of secondary ozonides (SOZs) with amines. SOZs formed from ozonolysis of β-caryophyllene and α-humulene are found to be reactive to ethylamine and methylamine.

Our findings indicate that interaction of SOZs with amines in the atmosphere is very complicated, which is potentially a hitherto unrecognized source of N-containing compound formation.

We measured concentrations of three photooxidants – the hydroxyl radical, triplet excited states of organic carbon, and singlet molecular oxygen – in fine particles collected over a year. Concentrations are highest in extracts of fresh biomass burning particles, largely because they have the highest particle concentrations and highest light absorption. When normalized by light absorption, rates of formation for each oxidant are generally similar for the four particle types we observed.

The effect of dust emitted from desertic surfaces upon climate and ecosystems depends on size and mineralogy, but data from soil mineral atlases of desert soils are scarce. We performed particle-size distribution, mineralogy, and Fe speciation in southern Morocco. Results show coarser particles with high quartz proportion are near the elevated areas, while in depressed areas, sizes are finer, and proportions of clays and nano-Fe oxides are higher. This difference is important for dust modelling.

Short summary
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.
