Black carbon (BC) aerosols play important roles in Arctic climate change, yet they are not well understood because of limited observational data. We observed BC mass concentrations (mBC) in the western Arctic Ocean during summer and early autumn 2016–2020. The mean mBC in 2019 was much higher than in other years. Biomass burning was likely the dominant BC source. Boreal fire BC transport occurring near the surface and/or in the mid-troposphere contributed to high-BC events in the Arctic Ocean.

The temperature and acidity dependence of yields and chemical compositions of the α-pinene ozonolysis SOA were systematically investigated using a newly developed compact chamber system. Increases in SOA yields were observed with the decrease in temperature and under acidic seed conditions. The differences in chemical compositions between acidic and neutral seed conditions were characterized and explained from the viewpoints of acid-catalyzed reactions. Some organosulfates were newly detected.

Air pollution in Delhi during the post-monsoon period is severe, and association with intensive crop residue burning (CRB) over Punjab state has attracted attention. However, the relationship has been unclear as the CRB emissions conventionally derived from satellites were underestimated due to clouds or thick smoke/haze over the region. We evaluated the impact of CRB on PM2.5 to be about 50 %, based on a combination of numerical modeling and an observation network using low-cost sensors we installed.

This study examines aerosol hygroscopicity and mixing states at Mt. Hua (2060 m), a key free-tropospheric site in central China. We found size-dependent hygroscopicity, source-related variations, and humidity-driven processing, distinguishing this region from other high-altitude sites, which may provide key constraints for aerosol-cloud and regional climate models.

Water-soluble pyrogenic carbon (WSPyC) is long-lived in the ocean and plays a role in regulating climate. This study observed the variations in concentration and sources of WSPyC in atmospheric aerosols. The results suggest that WSPyC can form through the oxidation of soot during atmospheric transport, highlighting this process as an important pathway before aerosols are deposited into the ocean.

It is essential to understand how biologically productive oceanic regions during spring phytoplankton blooms after sea ice melting contribute to the sea-to-air emission flux of atmospheric organic aerosols (OAs) in the subarctic oceans. Our shipboard measurements highlight the preferential formation of N-containing secondary water-soluble OAs associated with the predominant diatoms including ice algae during the bloom after sea ice melting/retreat in the subarctic ocean.

This study investigated airborne endotoxins varying with height and season in northern China. By analyzing specific hydroxy fatty acids in aerosols, we estimated endotoxins at ground level and higher altitudes. Higher concentrations were observed near the ground during winter, likely driven by microbial emissions and combustion sources. Our findings suggest that air pollution and meteorological factors can influence endotoxin concentrations, posing potential health risks in urban environments.

Two shipborne observations in the South China Sea (SCS) in summer and winter 2021 were conducted. Our study found aerosol hygroscopicity is higher in the SCS in summer than winter, with significant influences from various terrestrial air masses. Aerosol size distribution had a stronger effect on activation ratio than aerosol hygroscopicity in summer and vice versa in winter. Our study provides valuable information to enhance our understanding of cloud condensation nuclei activities in the SCS.

Monthly ice core records spanning 350 years from Greenland show trends in refractory black carbon (rBC) concentrations and sizes. rBC levels have increased since the 1870s due to the inflow of anthropogenic rBC, with larger diameters than those from biomass burning (BB) rBC. High summer BB rBC peaks may reduce the ice sheet albedo, but BB rBC showed no increase until the early 2000s. These results are vital for validating aerosol and climate models.

Carbonate carbon (CC) is not negligible in Arctic total suspended particles (TSP). If not considered, CC biases the contribution of elemental and organic carbon. CC content in TSP was strongly reflected in the δ13C values of total carbon (TC). Carbon contribution from CaCO3 supports strong dependence of CC and δ13C on Ca. Finally, two hypothetical CC sources were identified based on the analysis of air mass back trajectories – dust resuspension and marine microorganisms.

This study investigated the daytime secondary organic aerosol (SOA) formation in urban plumes. We observed a significant daytime SOA formation through gas–particle partitioning when the site was affected by urban plumes. A box model simulation indicated that urban pollutants (nitrogen oxide and volatile organic compounds) could enhance the oxidizing capacity, while the elevated volatile organic compounds were mainly responsible for promoting daytime SOA formation.

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.

Intensified heatwaves with the global warming have influenced new particle formation (NPF) and related aerosol physicochemical properties. We show that aerosol optical hygroscopicity (f(RH)) was generally higher on NPF event days than non-event cases, likely due to enhanced secondary formation and subsequent growth of both pre-existing and newly formed particles with stronger photooxidation specifically under persistent heatwaves. This would further impact the aerosol direct radiative forcing.

Using simultaneous measurements of DMA–CCNC, H(/V)TDMA, and DMA–SP2, impacts of primary emissions and secondary aerosol formations on changes in aerosol physicochemical properties were comprehensively investigated. It was found that intercomparisons among aerosol mixing-state parameters derived from different techniques can help us gain more insight into aerosol physical properties which, in turn, will aid the investigation of emission characteristics and secondary aerosol formation pathways.

In a May–June 2021 expedition in the South China Sea, we analyzed black and brown carbon in marine aerosols, key to light absorption and climate impact. Using advanced in situ and microscope techniques, we observed particle size, structure, and tar balls mixed with various elements. Results showed biomass burning and fossil fuels majorly influence light absorption, especially during significant burning events. This research aids the understanding of carbonaceous aerosols' role in marine climate.

Fatty alcohols (FAs) are major components of surface lipids in plant leaves and serve as surface-active aerosols. Our study on the aerosol size distributions in a forest suggests that secondary FAs (SFAs) originated from plant waxes and that leaf senescence status is likely an important factor controlling the size distribution of SFAs. This study provides new insights into the sources of primary biological aerosol particles (PBAPs) and their effects on the aerosol ice nucleation activity.

This study investigated the effect of COVID-19 lockdown (LCD) measures on the formation and evolutionary process of diacids and related compounds from field observations. Results demonstrate that more aged organic aerosols are observed during the LCD due to the enhanced photochemical oxidation.

Light-absorbing particles from combustion processes are important contributors to climate warming. Their highly variable spectral light absorption properties need to be monitored in the field. Commonly used methods show measurement artefacts that are difficult to correct. We introduce a new instrument that is based on the photoacoustic effect. Long-term operation in the Finnish Arctic demonstrates the applicability of the new instrument for unattended light absorption monitoring.

Using year-long aerosol mass spectrometer measurements, roles of secondary organic aerosols (SOA) during haze formations in an urban area of southern China were systematically analyzed. Almost all severe haze events were accompanied by continuous daytime and nighttime SOA formations, whereas coordinated gas-phase photochemistry and aqueous-phase reactions likely played significant roles in quick daytime SOA formations, and nitrate radicals played significant roles in nighttime SOA formations.

This study examined the summertime fluorescence properties of water-soluble organic carbon (WSOC) in aerosols over the western Arctic Ocean. We found that the WSOC in fine-mode aerosols in coastal areas showed a higher polycondensation degree and aromaticity than in sea-ice-covered areas. The fluorescence properties of atmospheric WSOC in the summertime marine Arctic boundary can improve our understanding of the WSOC chemical and biological linkages at the ocean–sea-ice–atmosphere interface.

This study investigated the role of the secondary organic aerosol (SOA) loading on the molecular composition of wintertime urban aerosols by ultrahigh-resolution mass spectrometry. Results demonstrate that the SOA loading is an important factor associated with the oxidation degree, nitrate group content, and chemodiversity of nitrooxy–organosulfates. Our study also found that the hydrolysis of nitrooxy–organosulfates is a possible pathway for the formation of organosulfates.

Water-soluble organic nitrogen (WSON) in marine aerosols is important for biogeochemical cycling of bioelements. Our shipboard measurements suggested that reactive nitrogen produced and exuded by nitrogen-fixing microorganisms in surface seawater likely contributed to the formation of WSON aerosols in the subtropical North Pacific. This study provides new implications for the role of marine microbial activity in the formation of WSON aerosols in the ocean surface.

We present intensive field measurement of ClNO2 in the Pearl River Delta in 2019. Large variation in the level, formation, and atmospheric impacts of ClNO2 was found in different air masses. ClNO2 formation was limited by the particulate chloride (Cl−) and aerosol surface area. Our results reveal that Cl− originated from various anthropogenic emissions rather than sea sources and show minor contribution to the O3 pollution and photochemistry.

Using a global aerosol model, we find that the source contributions to radiative effects of black carbon (BC) in the Arctic are quite different from those to mass concentrations and deposition flux of BC in the Arctic. This is because microphysical properties (e.g., mixing state), altitudes, and seasonal variations of BC in the atmosphere differ among emissions sources. These differences need to be considered for accurate simulations of Arctic BC and its source contributions and climate impacts.

This study investigated the size dependence and diurnal variation in organic aerosol hygroscopicity, volatility, and cloud condensation nuclei (CCN) activity. We found that the physical properties of OA could vary in a large range at different particle sizes and affected the number concentration of CCN (NCCN) at all supersaturations. Our results highlight the importance of evaluating the atmospheric evolution processes of OA at different size ranges and their impact on climate effects.

Using simultaneous measurements of a humidified nephelometer system and an aerosol chemical speciation monitor in winter in Guangzhou, the strongest scattering ability of more oxidized oxygenated organic aerosol (MOOA) among aerosol components considering their dry-state scattering ability and water uptake ability was revealed, leading to large impacts of MOOA on visibility degradation. This has important implications for visibility improvement in China and aerosol radiative effect simulation.

Light-absorbing brown carbon (BrC) plays an important role in climate change and atmospheric chemistry. Here we investigated the seasonal and diurnal variations in water-soluble BrC in PM2.5 in the megacity Tianjin in coastal China. Results of the source apportionments from the combination with organic molecular compositions and optical properties of water-soluble BrC reveal a large contribution from primary bioaerosol particles to BrC in the urban atmosphere.

We use a model constrained using observations to study the formation of nitrate aerosol in and downwind of a representative megacity. We found different contributions of various chemical reactions to ground-level nitrate concentrations between urban and suburban regions. We also show that controlling VOC emissions are effective for decreasing nitrate formation in both urban and regional environments, although VOCs are not direct precursors of nitrate aerosol.

In this study, we investigated the hygroscopicity of submicron aerosols at a rural site in the North China Plain during the winter of 2018, using a HTDMA and a CV-ToF-ACSM. We observed differences in aerosol hygroscopicity during two distinct episodes with different primary emissions and secondary aerosol formation processes. These results provide an improved understanding of the complex influence of sources and aerosol evolution processes on their hygroscopicity.

We present the hygroscopicity of 23 organic species with different physicochemical properties using a hygroscopicity tandem differential mobility analyzer (HTDMA) and compare the results with previous studies. Based on the hygroscopicity parameter κ, the influence of different physicochemical properties that potentially drive hygroscopicity, such as the functionality, water solubility, molar volume, and O : C ratio of organics, are examined separately.

In spring 2018 the research aircraft Polar 5 conducted flights in the Arctic atmosphere. The flight operation was from Station Nord in Greenland, 1700 km north of the Arctic Circle (81°43'N, 17°47'W). Using a mass spectrometer we measured more than 100 organic compounds in the air. We found a clear signature of natural organic compounds that are transported from forests to the high Arctic. These compounds have the potential to change the cloud cover and energy budget of the Arctic region.

We attempt to understand the current state of East Asian organic aerosols with both the molecular marker approach and 14° C data of carbonaceous components. A significant positive correlation of nonfossil- and fossil-derived organic carbon with levoglucosan suggests the importance of biomass burning (BB) and coal combustion sources in the East Asian outflow. Thus, attribution of ambient levoglucosan levels over the western North Pacific to the impact of BB emission may cause large uncertainty.

The tropical Indian Ocean (IO) is expected to be a significant source of water-soluble organic carbon (WSOC), which is relevant to cloud formation. Our study showed that marine secondary organic formation dominantly contributed to the aerosol WSOC mass at the high-altitude observatory in the southwest IO in the wet season in both marine boundary layer and free troposphere (FT). This suggests that the effect of marine secondary sources is important up to FT, a process missing in climate models.

Vertical profiles of black carbon (BC) in the Arctic were measured during the PAMARCMiP aircraft-based experiment in spring 2018 and compared with those observed during previous aircraft campaigns in 2008, 2010, and 2015. Their differences were explained primarily by the year-to-year variation of biomass burning activities in northern midlatitudes over Eurasia. Our observations provide a bases to evaluate numerical model simulations that assess the BC radiative effects in the Arctic spring.

Reliable values of mass absorption cross sections (MACs) of black carbon (BC) are required to determine mass concentrations of BC at Arctic sites using different types of filter-based absorption photometers. We successfully estimated MAC values for these instruments through comparison with independent measurements of BC by a continuous soot monitoring system called COSMOS. These MAC values are consistent with each other and applicable to study spatial and temporal variation in BC in the Arctic.

This study presents vertical profiles of biogenic and anthropogenic secondary organic aerosols (SOAs) in the urban boundary layer based on a 325 m tower in Beijing in late summer. The increases in the isoprene and toluene SOAs with height were found to be more related to regional transport, whereas the decrease in those from monoterpenes and sesquiterpene were more subject to local emissions. Such complicated vertical distributions of SOA should be considered in future modeling work.

HO2 radicals play key roles in tropospheric chemistry, their levels in ambient air not yet fully explained by sophisticated models. Here we measured HO2 uptake kinetics onto ambient aerosols in real time using a self-built online system and investigated the impacting factors on such processes by coupling with other instrumentations. The role of the HO2 uptake process in O3 formation is also discussed. Results give useful information for coordinated control of aerosol and ozone pollutants.

Absorbing aerosols are warming the planet and accurate measurements of their concentrations in pristine environments are needed. We applied eight different absorbing-aerosol measurement methods in a field campaign at the Arctic Pallas station. The filter-based techniques were found to be the most sensitive to detect the minuscule amounts of black carbon present, showing a 40 % agreement between them. Our results help to reduce uncertainties in absorbing aerosol measurements.

We found that organic aerosol factors with identified sources perform much better than oxidation level parameters in characterizing variations in organic aerosol hygroscopicity, and secondary aerosol formations associated with different sources have distinct effects on organic aerosol hygroscopicity. It reveals that source-oriented organic aerosol hygroscopicity investigations might result in more appropriate parameterization approaches in chemical and climate models.

This study investigated the contribution of new particle formation (NPF) events to the number concentration of cloud condensation nuclei (NCCN) and its controlling factors in the Pearl River Delta region. The results show that the surfactant effect can decrease the critical diameter and significantly increase the NCCN during the NPF event. In addition, the growth rate is founded to be the most important controlling factor that affects NCCN for growth of newly-formed particles to the CCN sizes.

Aerosol particles influence the Arctic climate by interacting with solar radiation, forming clouds, and melting surface snow and ice. Individual-particle analyses using transmission electron microscopy (TEM) and model simulations provide evidence of biomass burning and anthropogenic contributions to the Arctic aerosols by showing a wide range of compositions and mixing states depending on sampling altitude. Our results reveal the aerosol aging processes and climate influences in the Arctic.

Our observations provide detailed information on the abundance and vertical distribution of dicarboxylic acids, oxoacids and α-dicarbonyls in PM2.5 collected at three heights based on a 325 m meteorological tower in Beijing in summer.

Short summary
Offline analyses of the hygroscopicity and composition of atmospheric aerosols are complementary to online analyses in view of the applicability to broader sizes, specific compound groups, and investigations at remote sites. This offline study characterized the composition of water-soluble matter in aerosols and their humidity-dependent hygroscopicity on Okinawa, a receptor site of East Asian outflow. Further, comparison with online analyses showed the appropriateness of the offline method.
