Short summary
In this study, the interactions between α-pinene and marine emission dimethyl sulfide (DMS) are investigated. It is found that the yield of secondary organic aerosol initially increases and then decreases with the increasing DMS/α-pinene ratio. This trend can be explained by OH regeneration, acid-catalyzed reactions, and the change in OH reactivity, etc. These findings can improve our understanding of atmospheric processes in coastal areas.

Short summary
Authentic aerosols emitted from residential wood stoves and open burning processes are only slightly oxidized by ozone in the atmosphere. Under dry conditions, the reaction does not proceed to completion, while under high humidity conditions, the reactivity proceeds further. These results indicate that the reactivity with ozone is likely impacted by aerosol phase state (e.g., aerosol viscosity).

Phytoplankton blooms dynamically enrich dissolved organic carbon (DOC) in sea spray aerosol by 10-30 times, with proteins and saccharides transferring at different bloom stages. The sea-to-air transfer of DOC is driven by the synergy of biological and the interaction between DOC and bubble rupture. This synergistically-driven DOC flux affects aerosol properties and climate, highlighting the ocean-atmosphere link in organic carbon cycling.

This study examines the transformation of organosulfates through reaction with HO• radicals. The results show that the nature of substituents on the carbon chain can effectively affect the decomposition rate of organosulfates, and ozone is unveiled as a complementary oxidant in the intermediate steps of this decomposition. The primary products from these reactions include carbonyl compounds and inorganic sulfate, which highlights the role of organosulfates in altering aerosol chemical composition.

A comprehensive understanding of the optical properties of brown carbon (BrC) is essential to accurately assess its climatic effects. Based on multi-site spectroscopic measurements, this study demonstrated the significant spatial heterogeneity in the optical and structural properties of water-soluble organic carbon (WSOC) in different regions of China and revealed factors affecting WSOC light absorption and the relationship between fluorophores and light absorption of WSOC.

Our study analyzes real-time emissions of organic vapors from solid fuel combustion. Using the mass spectrometer, we tested various fuels, finding higher emission factors for organic vapors from wood burning. Intermediate-volatility organic compounds constituted a significant fraction of emissions in solid fuel combustion. Statistical tests identified unique potential markers. Our insights benefit air quality, climate, and health, aiding accurate emission assessments.

This study investigated the distribution and sources of non-methane hydrocarbons (NMHCs) in the lower atmosphere over the marginal seas of China. NMHCs, a subset of volatile organic compounds (VOCs), play a crucial role in atmospheric chemistry. Derived from systematic atmospheric sampling in coastal cities and marginal sea regions, this study offers valuable insights into the interaction between land and sea in shaping offshore atmospheric NMHCs.

Aromatic acids can be transferred from seawater to the atmosphere through bubble bursting. The air–sea transfer efficiency of aromatic acids was evaluated by simulating SSA generation with a plunging jet. As a whole, the transfer capacity of aromatic acids may depend on their functional groups and on the bridging effect of cations, as well as their concentration in seawater, as these factors influence the global emission flux of aromatic acids via SSA.

This study explores the pH effect on the reaction of dissolved SO2 with selected organic peroxides. Results show that the formation of organic and/or inorganic sulfate from these peroxides strongly depends on their electronic structures, and these processes are likely to alter the chemical composition of dissolved organic matter in different ways. The rate constants of these reactions exhibit positive pH and temperature dependencies within pH 1–10 and 240–340 K ranges.

We conducted burning experiments to simulate various types of solid fuel combustion, including residential burning, wildfires, agricultural burning, cow dung, and plastic bag burning. The chemical composition of the particles was characterized using mass spectrometers, and new potential markers for different fuels were identified using statistical analysis. This work improves our understanding of emissions from solid fuel burning and offers support for refined source apportionment.

The promotion of soluble saccharides on sea spray aerosol (SSA) generation and the changes in particle morphology were observed. On the contrary, the coexistence of surface insoluble fatty acid film and soluble saccharides significantly inhibited the production of SSA. This is the first demonstration that hydrogen bonding mediated by surface-insoluble fatty acids contributes to saccharide transfer in seawater, providing a new mechanism for saccharide enrichment in SSA.

SO2 significantly promotes particle formation during cyclooctene ozonolysis. Carboxylic acids and their dimers were major products in particles formed in the absence of SO2. SO2 can induce production of organosulfates with stronger particle formation ability than their precursors, leading to the enhancement in particle formation. Formation mechanisms and structures of organosulfates were proposed, which is helpful for better understanding how SO2 perturbs the formation and fate of particles.

We presented yields and compositions of Si-containing SOAs generated from the reaction of cVMSs (D3–D6) with OH radicals. NOx played a negative role in cVMS SOA formation, while ammonium sulfate seeds enhanced D3–D5 SOA yields at short photochemical ages under high-NOx conditions. The aerosol mass spectra confirmed that the components of cVMS SOAs significantly relied on OH exposure. A global cVMS-derived SOA source strength was estimated in order to understand SOA formation potentials of cVMSs.

Short summary
Ozone formation is enhanced by higher OH concentration and higher temperature but is influenced little by SO2. SO2 can largely enhance the particle formation. Organo-sulfates and organo-nitrates are detected in the formed particles, and the presence of SO2 can promote the formation of organo-sulfates. The results provide a scientific basis for systematically evaluating the effects of SO2, OH concentration, and temperature on the oxidation of mixed organic gases in the atmosphere.

This study explores the effect of pyruvic acid (PA) both in the SO3 hydrolysis and in sulfuric-acid-based aerosol formation. Results show that in dry and polluted areas, PA-catalyzed SO3 hydrolysis is about 2 orders of magnitude more efficient at forming sulfuric acid than the water-catalyzed reaction. Moreover, PA can effectively enhance the ternary SA-PA-NH3 particle formation rate by up to 4.7×102 relative to the binary SA-NH3 particle formation rate at cold temperatures.

The promotion effects of SO2 and NH3 on particle and organosulfur compound formation from 1,2,4-trimethylbenzene (TMB) photooxidation were observed for the first time. The enhanced organosulfur compounds included hitherto unidentified aromatic sulfonates and organosulfates (OSs). OSs were produced via acid-driven heterogeneous chemistry of hydroperoxides. The production of organosulfur compounds might provide a new pathway for the fate of TMB in regions with considerable SO2 emissions.

Short summary
SOA formation from the mixed anthropogenic volatile organic compounds was enhanced compared to the predicted SOA mass concentration based on the SOA yield of single species; interaction occurred between intermediate products from the two precursors. Interactions between the intermediate products from the mixtures and the effect on SOA formation give us a further understanding of the SOA formed in the atmosphere.

Short summary
In this study, we have investigated the distinct impacts of humidity on the ozonolysis of two structurally different monoterpenes (limonene and Δ3-carene). We found that the molecular structure of precursors can largely influence the SOA formation under high RH by impacting the multi-generation reactions. Our results could advance knowledge on the roles of water content in aerosol formation and inform ongoing research on particle environmental effects and applications in models.
In this study, we have investigated the distinct impacts of humidity on the ozonolysis of two...
