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.

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 BrC dynamics and its sources in diverse environments for global climate effects.

By integrating field measurements with an interpretable ensemble machine learning framework, we comprehensively identified key driving factors of nitro-aromatic compounds (NACs), demonstrated complex interrelationships, and quantified their contributions across different locations. This work provides a reliable modeling approach for recognizing causes of NAC pollution, enhances our understanding of variations of atmospheric NACs, and highlights the necessity of strengthening emission controls.

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.

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.

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.

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.

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 show that in-cloud aqueous processing facilitates the formation of brown carbon (BrC), based on the simultaneous measurements of the light-absorption properties of the cloud residuals, cloud interstitial, and cloud-free particles. 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 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.

A tunnel test was initiated to measure the vehicular IVOC emissions under real-world driving conditions. Higher SOA formation estimated from vehicular IVOCs compared to those from traditional VOCs emphasized the greater importance of IVOCs in modulating urban SOA. The results also revealed that non-road diesel-fueled engines greatly contributed to IVOCs in China.

We build a novel system that utilizes an aerodynamic aerosol classifier (AAC) combined with a single-particle aerosol mass spectrometry (SPAMS) to simultaneously characterize the volume equivalent diameter (Dve), chemical compositions, and effective density (ρe) of individual particles in real time. A test of the AAC-SPAMS with both spherical and aspherical particles shows that the deviations between the measured and theoretical values are less than 6 %.

Based on the analysis of the morphology and mixing structure of the activated and unactivated particles, our results emphasize the role of in-cloud processes in 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 for their evolution and climate impact.

Short summary
The sources of aerosol Fe, especially soluble aerosol Fe, remain to be constrained. The stable isotope ratio of Fe has emerged as a potential tracer for discriminating and quantifying sources of aerosol Fe. In this review, we examine the state of the field for using Fe isotopes as an aerosol source tracer, and constraints on endmember signatures.
The sources of aerosol Fe, especially soluble aerosol Fe, remain to be constrained. The stable...
