Rainwater samples collected at the summit of Mount Tai were analyzed for ice-nucleating particles (INPs). Our findings revealed that INP concentrations peaked in spring, driven predominantly by long-range transport of dust aerosols. Mineral dust contributed 43.6 % of annual INPs, with its contribution rising sharply to 71.7 % in spring. Satellite observations further revealed that the long-range transport of dust in spring promotes large-scale cloud formation over the NCP region.

Field observations were conducted at the summit of Changbai Mountain in northeast Asia. The cumulative number concentration of ice-nucleating particles (INPs) varied from 1.6 × 10−3 to 78.3 L−1 over the temperature range of −5.5 to −29.0 ℃. Biological INPs (bio-INPs) accounted for the majority of INPs, and the proportion exceeded 90% above −13.0 ℃. Planetary boundary layer height, valley breezes, and long-distance transport of air mass influence the abundance of bio-INPs.

In this study, different soot particles were analyzed to better understand their behavior. It was discovered that water-soluble substances in soot facilitate water adsorption at low humidity while increasing the number of water layers at high humidity. Soot from organic fuels exhibits hygroscopicity influenced by organic carbon and microstructure. Additionally, the presence of sulfate ions due to the oxidation of SO2 enhances soot's hygroscopicity.

This study reports field measurements of particulate organonitrates in a mixed anthropogenic-biogenic subtropical atmosphere, revealing contrasting formation regimes between urban and rural sites. Daytime photochemistry and regional transport dominated urban organonitrates, while nighttime formation from anthropogenic precursors and refractory organic nitrate from biomass burning both contributed to rural organonitrates. Our findings improve understanding of organonitrate formation.

We conducted four‑season field measurements of primary intermediate‑volatility organic compounds (IVOCs) at an urban site in the Yangtze River Delta, China. Measured IVOCs peaked in summer and reached a minimum in winter, driven by temperature‑dependent evaporative emissions and gas/particle partitioning. Our findings highlight that evaporative emissions are increasingly important for urban IVOC budgets under climate warming and should be considered in air quality models and control strategies.

Organic nitrates influence ozone formation and fine particle pollution, yet measuring them in both gas and particle phases remains challenging. We developed an instrument using thermal dissociation with NO2 detector to quantify two organic nitrate classes in both phases. A correction-model corrects biases from nitrogen oxides. Field tests in Guangzhou showed continuous tracking of organic nitrate levels and phase distribution, a tool for studying reactive nitrogen in urban air.

Fireworks release tiny particles that affect air quality. In Guangzhou, we tracked how barium particles from fireworks change in the air. Fireworks raised barium levels up to one thousand times above normal. These particles transformed through chemical reactions. Local policies cut pollution in restricted areas. Long-term health risks stay low, but short-term exposure can be much higher, which may concern children. Our findings help explain particle aging and guide air quality management.

This study measured a statistically representative number of 2-month-old and 2-year-old eucalyptus trees using both leaf cuvettes and dynamic branch chambers. It demonstrated equivalent isoprene results between the two enclosure methods, yet contrasting emission magnitude and speciation among age groups. Current seedling- and adult-tree-mixed emission factor databases may thus misjudge ozone and secondary organic aerosol simulation, thus age-resolved data will improve air quality forecasts.

Cloud substantially changes the compositions organic aerosol. How cloud processing of organics occur on molecular level remains unclear. We found that compared with cloud free particles, organics in cloud contains more large molecules likely due to accretion reactions and has more nitrogen-containing compounds. We identify some new compounds formed in cloud. Such modifications of the organics in cloud can further change its physicochemical properties, and impact on climate and human health.

This study conducted long-term measurements of oxalic acid and molecular markers of primary anthropogenic emissions and secondary organic aerosols (SOA). We found that the reductions in anthropogenic precursors had limited impacts on SOA formation. The results highlight the increasing role of gas-phase oxidation under low-pollution conditions, emphasizing the need for effective ozone control strategies to mitigate SOA formation.

Our study examined brown carbon – organic aerosols that absorb light – at the remote Tibet and urban Guangzhou. Field data showed Tibet’s brown carbon absorbs about 10 times less than Guangzhou’s, due to cleaner air. Yet, over 75 % of its light absorption still comes from primary emission, which causes over 98 % of its climate-warming effect in both places. This study advances understanding of brown carbon dynamics and its sources in diverse environments for global climate effects.

We developed the Speciated Isoprene Emission Model with Model of Emissions of Gases and Aerosols from Nature Algorithm for China to improve biogenic emission estimates using updated vegetation data and local measurements. The model predicts summer 2013 emissions of 10.92–11.37 teragrams of carbon. Validation shows our model performs better than the existing models, revealing underestimated isoprene impacts on ozone pollution in eastern China.

This study presented field measurements of PM2.5 and its chemical composition at a regional background site in the Pearl River Delta (PRD) from 2007 to 2020. As air quality improved, secondary species became more dominant. The changes in chemical composition led to the reductions in aerosol acidity, liquid water content and light extinction coefficient. Our results help to improve understanding of the secondary species formation under decreasing anthropogenic emissions.

We measured ambient OH and HO2* (HO2 and contribution from RO2, organic peroxyl radicals) concentrations at a subtropical rural site and compared our observations with model results. During warm periods, the model overestimated concentrations of OH and HO2, leading to overestimation of ozone and nitric acid production. Our findings highlight the need to better understand how OH and HO2 are formed and removed, which is important for accurate air quality and climate predictions.

This study revealed the existence of significant species-specific adsorptive and reactive losses of monoterpenes and sesquiterpenes in dynamic chambers. The deuterated α-pinene-d3 and β-caryophyllene-d2 were proven as effective surrogates in tracing these losses for some key monoterpenes and sesquiterpenes. The findings highlight the importance of selecting internal surrogates that closely match the adsorptive and reactive behaviors of target compounds for precise loss correction.

Environmental persistent free radicals (EPFRs) and reactive oxygen species (ROSs) play an active role in the atmosphere. Despite control measures having effectively reduced their emissions, reductions were less than in PM2.5. Emission control measures performed well in achieving Parade Blue, but reducing the impact of the atmosphere on human health remains challenging. Thus, there is a need to reassess emission control measures to better address the challenges posed by EPFRs and ROSs.

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.

The formation pathways of nitrogen-containing compounds (NOCs) in the atmosphere remain unclear. We investigated the composition of aerosols and fog water by state-of-the-art mass spectrometry and compared the formation pathways of NOCs. We found that NOCs in aerosols were mainly formed through nitration reaction, while ammonia addition played a more important role in fog water. The results deepen our understanding of the processes of organic particulate pollution.

We found that for ultrapure water batch leaching, the difference in specific experimental parameters, including agitation methods, filter pore size, and contact time, only led to a small and sometimes insignificant difference in determined aerosol trace element solubility. Furthermore, aerosol trace element solubility determined using four common ultrapure water leaching protocols showed good agreement.

Using in situ VOC flux measurements, we reveal that the freshwater wetland is a potential source of atmospheric VOCs and that litter decomposition enhances net VOC emission. Ambient temperature is the key factor driving the seasonal variation of net VOC flux. Notably, the release or uptake of VOCs varies depending on chemical groups and is jointly controlled by biotic and abiotic processes.

In this study, different soot particles were analyzed to better understand their behavior. It was discovered that water-soluble substances in soot facilitate water adsorption at low humidity while increasing the number of water layers at high humidity. Soot from organic fuels exhibits hygroscopicity influenced by organic carbon and microstructure. Additionally, the presence of sulfate ions due to the oxidation of SO2 enhances soot's hygroscopicity.

The solubility of vital and toxic trace elements delivered by the atmosphere determines their potential to fertilise or limit ocean productivity. A poor understanding of aeolian trace element solubility and the absence of a standard method to define this parameter hinder accurate model representation of the impact of atmospheric deposition on ocean productivity in a changing climate. The inter-journal special issue aims at “Reducing Uncertainty in Soluble aerosol Trace Element Deposition”.

During the R/V Xuelong cruise observation over the Ross Sea, Antarctica, the mass concentrations of water-soluble Ca2+ and the mass spectra of individual calcareous particles were measured. Our results indicated that lower temperature, lower wind speed, and the presence of sea ice may facilitate Ca2+ enrichment in sea spray aerosols and highlighted the potential contribution of organically complexed calcium to calcium enrichment, which is inaccurate based solely on water-soluble Ca2+ estimation.

We studied the variability and molecular composition of ambient oxidized organic nitrogen (OON) in both gas and particle phases using a state-of-the-art online mass spectrometer in urban air. Biomass burning and secondary formation were found to be the two major sources of OON. Daytime nitrate radical chemistry for OON formation was more important than previously thought. Our results improved the understanding of the sources and molecular composition of OON in the polluted urban atmosphere.

The hydroxyl (OH) and closely coupled hydroperoxyl (HO2) radicals are vital for their role in the removal of atmospheric pollutants. In less polluted regions, atmospheric models over-predict HO2 concentrations. In this modelling study, the impact of heterogeneous uptake of HO2 onto aerosol surfaces on radical concentrations and the ozone production regime in Beijing in the summertime is investigated, and the implications for emissions policies across China are considered.

To investigate the impact of aging processes on organic aerosols (OA), we conducted a comprehensive field study at a continental remote site using an on-line mass spectrometer. The results show that OA in the Chinese outflows were strongly influenced by upwind anthropogenic emissions. The aging processes can significantly decrease the OA volatility and result in a varied viscosity of OA under different circumstances, signifying the complex physiochemical properties of OA in aged plumes.

The Hybrid Activity Model (HAM) is a promising new droplet growth model that can be potentially used for the analysis of any type of atmospheric compound. HAM may potentially improve the representation of hygroscopicity of organic aerosols in large-scale global climate models (GCMs), hence reducing the uncertainties in the climate forcing due to the aerosol indirect effect.

We show a significant enhancement of nitrate mass fraction in cloud water and relative intensity of nitrate in the cloud residual particles and highlight that hydrolysis of N2O5 serves as the critical route for the in-cloud formation of nitrate, even during the daytime. Given that N2O5 hydrolysis acts as a major sink of NOx in the atmosphere, further model updates may improve our understanding about the processes contributing to nitrate production in cloud and the cycling of odd nitrogen.

The particle size and chemical composition of bioaerosol were analyzed based on single particle aerosol mass spectrometer. Fungal aerosol of 10 μm was measured for the first time and the characteristic spectrum of bioaerosol was updated. The ion peak ratio method can distinguish bioaerosols from interferers by 97 %. The factors influencing the differentiation of bioaerosols are also discussed. Single particle mass spectrometry can be a new method for real-time identification of bioaerosols.

We have investigated the budget of HONO at an urban site in Guangzhou. Budget and comprehensive uncertainty analysis suggest that at such locations as ours, HONO direct emissions and NO + OH can become comparable or even surpass other HONO sources that typically receive greater attention and interest, such as the NO2 heterogeneous source and the unknown daytime photolytic source. Our findings emphasize the need to reduce the uncertainties of both conventional and novel HONO sources and sinks.

Aerosol hygroscopicity is critical when evaluating its effect on visibility and climate. Here, the size-resolved particle hygroscopicity at five sites in China is characterized using field measurements. We show the distinct behavior of hygroscopic particles during pollution evolution among the five sites. Moreover, different hygroscopic behavior during NPF events were also observed. The dataset is helpful for understanding the spatial variability in particle composition and formation mechanisms.

While extensive laboratory evidence indicated the formation of BrC in aqueous phase, our study represents the first attempt to show the possibility in real clouds, which would have potential implications in the atmospheric evolution and radiation forcing of BrC.

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.

Water-soluble organic compounds (WSOCs) play important roles in atmospheric particle formation, migration, and transformation processes. In this work, size-segregated atmospheric particles were collected in a rural area of Beijing, and 3D fluorescence spectroscopy was used to investigate the optical properties of WSOCs as a means of inferring information about their atmospheric sources. It was found that these data could efficiently reveal the secondary transformation processes of WSOCs.

The emission of biogenic volatile organic compounds (BVOCs) from plant leaves is an essential part of biosphere–atmosphere interactions. Here we demonstrate how a dynamic chamber for measuring branch-scale BVOC emissions could be characterized both in the lab for adsorptive losses and in the field for ambient–enclosure environmental differences. The results also imply emission factors for terpenes might be underestimated if measured using dynamic chambers without certified transfer efficiencies.

We sampled cloud water at a remote mountain site and investigated the molecular characteristics. CHON and CHO are dominant in cloud water. No statistical difference in the oxidation state is observed between cloud water and interstitial PM2.5. Most of the formulas are aliphatic and olefinic species. CHON, with aromatic structures and organosulfates, are abundant, especially in nighttime samples. The in-cloud and multi-phase dark reactions likely contribute significantly.
