Influence of Aerosol Chemical Composition on Condensation Sink Efficiency and New Particle Formation in Beijing

Wei Du et al.

Summary: The chemical composition of preexisting particles plays an important role in inhibiting new particle formation events in urban areas, especially in the presence of ammonium nitrate-rich particles. Considering the effectiveness of these particles as a condensation sink can provide insights into the occurrence of new particle formation events.

Using Novel Molecular-Level Chemical Composition Observations of High Arctic Organic Aerosol for Predictions of Cloud Condensation Nuclei

Karolina Siegel et al.

Summary: Predictions of cloud droplet activation in the late summertime Arctic Ocean show that the aerosol in the High Arctic late summer is acidic and highly cloud active, with a substantial contribution from Aitken mode particles. The forecast underestimated the cloud condensation nuclei (CCN) number concentration by 4-8%.

Influence of organic aerosol molecular composition on particle absorptive properties in autumn Beijing

Jing Cai et al.

Summary: This study analyzed the molecular composition of organic aerosols collected in Beijing in autumn 2018 using a high-resolution mass spectrometer, and assessed their optical properties through light absorption measurements. The results showed that during intense haze periods, the enhanced light absorption of black carbon (BC) was associated with more oxygenated organic aerosols (e.g., dicarboxylic acids), while aromatic compounds and nitro-aromatics were related to high light absorption coefficients consistent with light-absorbing (brown) carbon (BrC).

Precursors and Pathways Leading to Enhanced Secondary Organic Aerosol Formation during Severe Haze Episodes

Yan Zheng et al.

Summary: This study used molecular analyses to investigate the key precursors and chemical processes of secondary organic aerosol formation in Beijing's winter PM2.5. Results showed that both photochemical and aqueous processing were involved in producing SOA during haze events, with important precursors including aromatics, isoprene, long-chain alkanes or alkenes, and carbonyls such as glyoxal and methylglyoxal. The enhanced SOA formation during severe haze events was mainly attributed to aqueous processing, highlighting the importance of reducing nitrogen oxides for future SOA control. Further research is needed on the formation of highly oxygenated long-chain molecules in polluted urban environments.

Photolytically induced changes in composition and volatility of biogenic secondary organic aerosol from nitrate radical oxidation during night-to-day transition

Cheng Wu et al.

Summary: Night-time reactions of biogenic volatile organic compounds (BVOCs) and nitrate radicals (NO3) can lead to the formation of NO3-initiated biogenic secondary organic aerosol (BSOANO(3)). Light exposure has significant impacts on the chemical composition and volatility of BSOANO(3), indicating substantial changes during photolytic ageing.

Ammonium nitrate promotes sulfate formation through uptake kinetic regime

Yongchun Liu et al.

Summary: This study found that the formation rate of particulate sulfate in the environment is exponentially correlated with the sulfur oxidation ratio, which is influenced by aerosol water content and relative humidity. The uptake of SO2 instead of the oxidation of S(IV) in the particle phase is the rate-determining step for sulfate formation, with NH3 playing an important role in the process.

Atmospheric gaseous hydrochloric and hydrobromic acid in urban Beijing, China: detection, source identification and potential atmospheric impacts

Xiaolong Fan et al.

Summary: This study focused on measuring gaseous HCl and HBr in urban Beijing during winter and early spring of 2019, identifying factors affecting their concentrations, such as atmospheric temperature, UVB, gaseous HNO3, and burning aerosols. The researchers found that gas-particle partitioning and reactions with OH radicals led to significant production of atomic Cl and Br during the day. On polluted days, the production rates of atomic Cl and Br were faster than on clean days, suggesting an important recycling pathway of halogen species in inland megacities.

Is reducing new particle formation a plausible solution to mitigate particulate air pollution in Beijing and other Chinese megacities?

Markku Kulmala et al.

Summary: Atmospheric gas-to-particle conversion plays a crucial role in haze formation in Chinese megacities, with over 65% of haze particles resulting from new particle formation. Reducing the subsequent growth rate of newly formed particles can delay haze episodes and improve air quality.

Insights into the molecular composition of semi-volatile aerosols in the summertime central Arctic Ocean using FIGAERO-CIMS

Karolina Siegel et al.

Summary: The remote central Arctic during summertime is characterized by low aerosol particle concentrations, but enhanced ocean-atmosphere fluxes due to increased ice-free conditions may have impacts on climate. Analysis of aerosol samples collected during the MOCCHA campaign revealed organic and sulfur-containing compounds, with a wide range of carbon numbers and O:C ratios. The study also showed that sulfur-containing compounds are mainly oxidation products of dimethyl sulfide (DMS), highlighting the complexity of aerosol composition in the central Arctic.

Formation of nighttime sulfuric acid from the ozonolysis of alkenes in Beijing

Yishuo Guo et al.

Summary: Significant nighttime sulfuric acid production was observed in urban Beijing during winter, with concentrations ranging between 1.0 and 3.0 x 10^6 cm(-3). Nighttime sulfuric acid events occurred most frequently on unpolluted nights with low vapor condensation sink, and were strongly correlated with O3, alkenes, and SO2 concentrations under very clean conditions. The concentration of sulfuric acid showed a strong correlation with the number concentration of sub-3 nm particles on both clean and polluted nights.

On the calibration of FIGAERO-ToF-CIMS: importance and impact of calibrant delivery for the particle-phase calibration

Arttu Ylisirnio et al.

Summary: This study identified a major source of error in the widely used syringe deposition calibration method that may lead to an overestimation of saturation vapour pressures. A new volatility calibration method using atomized calibration compounds was proposed, which showed significant differences in observed T-max values compared to the syringe method at the lowest solution concentration. The results highlight the importance of accurate calibration methods when deriving the volatility basis set from measurements of secondary organic aerosols.
