Aerosols are tiny particles that help clouds form and shape the climate. Newly formed particles must grow quickly to survive, yet how they grow is poorly understood. Combining laboratory experiments with field measurements, we tested seven common methods for predicting this growth. Most overestimate how strongly organic vapours condense onto particles, especially in polluted air, and even the best cannot fully explain the growth we observe, revealing a gap in our understanding.

Sulfuric acid (SA)–ammonia (NH3) nucleation cannot fully explain the observed new particle formation in cold regions. Using quantum chemical calculations and atmospheric cluster dynamics simulations, we find trifluoroacetic acid (TFA), a model perfluorocarboxylic acid (PFCA), markedly enhances SA–NH3 nucleation under cold conditions. This work reveals a PFCA-assisted nucleation mechanism and provides a molecular-level foundation for future atmospheric observations and aerosol modeling.

Estimating ozone formation potential from ambient volatile organic compound observations introduces bias by ignoring photochemical aging. Reconstructed initial emissions for a Shanghai suburban site reveal that primary oxygenated compounds and unmeasured species constitute 40.8 % and 12.6 % of total emissions, respectively. These overlooked precursors exhibit ozone formation capacity comparable to non-methane hydrocarbons, highlighting the need to include them in mitigation strategies.

Fine airborne particles affect air quality, human health, and climate, yet their molecular composition is difficult to measure. Using a newly characterized instrument that detects these molecules in real time, we carried out the first such study in an eastern Chinese city. We find that particle composition is shaped not only by molecules condensing from the air, but also by chemical reactions within the particles, with natural and human sources and regional transport all contributing.

We studied the kinetic relaxation in the formation of Criegee intermediates (CIs) from sesquiterpene ozonolysis. We found that the formation rate constant of sesquiterpene-derived CIs is initially unstable but gradually approaches a plateau that equals the rate constant of sesquiterpene ozonolysis. Our findings demonstrate that neglecting this kinetic relaxation may substantially overestimate the rate of sesquiterpene-derived CI formation and thus the CI-driven atmospheric oxidation capacity.

Current atmospheric models fail to explain observed sulfate concentrations in polluted and cold regions. Using Born–Oppenheimer molecular dynamics (BOMD) simulations, we show that hydroxymethanesulfonate and its isomer hydroxymethyl sulfite form mainly through reactions at air–water and air–ice surfaces rather than in bulk water. Strong acidity in polluted aerosols shifts formation toward hydroxymethyl sulfite. These findings help explain long-standing gaps between modeled and observed atmospheric sulfate.

Carcinogenic nitrosamines are pervasive in air pollution, yet their origins remain elusive. Using Born–Oppenheimer molecular dynamics, we demonstrate that nitrosamines form rapidly at the air–water interface via the reaction of amines with dinitrogen tetroxide. This mechanism also yields nitrous acid, thereby exacerbating pollution. By identifying this critical missing source of airborne carcinogens, our work underscores the necessity of integrating interfacial chemistry into atmospheric models.

Sulfuric acid (SA)-dominated nucleation cannot explain observed tropospheric particulate matter and cloud condensation nuclei. Via quantum chemical calculations and atmospheric cluster dynamics simulations, we find the role of nitric acid shifts from a marine boundary layer catalyst to an upper troposphere cluster core in HIO3–HIO2 nucleation, with particle formation rates surpassing established SA pathways, explaining unaccounted-for NPF amid falling sulfur and rising marine iodine emissions.

Marine new particle formation involves precursors such as methanesulfonic acid (MSA), iodic acid (IA), and dimethylamine (DMA), yet their nucleation mechanism remains incompletely understood. This study employs theoretical calculations to examine the IA–MSA–DMA system. We propose a nucleation mechanism that underscores the importance of synergistic interactions between sulfur-, iodine-, and nitrogen-containing vapors in driving marine new particle formation.

Gaseous sulfuric acid (H2SO4) is a key precursor in atmospheric cluster formation. Measurement challenges hinder its widespread observation. We conducted a three-year continuous measurement of H2SO4 in urban Beijing during 2019–2021, characterize its interannual, seasonal, and diurnal variations, and derives proxies to estimate its concentration. These proxies and parameters therein could be applicable at diverse sites and thus provide H2SO4 concentration covering many regions worldwide.

Semi-volatile NH4NO3 is a major component of atmospheric aerosols, and the activity coefficient of NH4NO3 is a key parameter in its estimations. Here we show different thermodynamic models differed in the NH4NO3 non-ideality representations, resulting in discrepancies in nitrate gas–particle partitioning predictions. The driving factors of chemical profiles and meteorological conditions are also investigated. This discrepancy can be an important source of uncertainty in air quality predictions.

This work extends current understanding of atmospheric chemistry across different NO regimes in Delhi. Field measurements during the early springtime of 2023 show enhanced nighttime production of N2O5 and ClNO2, driven by decreased NO and high particulate chloride concentrations. The inert particulate chloride can be efficiently activated to photolabile gases with the reduction of NO, and contribute to secondary pollution by enhancing atmospheric organics oxidation in Delhi.

I2O5 is known as a significant contributor to marine aerosol, yet the chemical mechanism remains unclear. The atmospheric complexity arises from intricate coupling effects between I2O5 and diverse chemical species. We performed Born-Oppenheimer molecular dynamics to elucidate the I2O5 hydrolysis mechanisms mediated by prevalent chemicals at the air-water interface. The proposed heterogeneous reactions provides molecular-level insight into the role of I2O5 in the atmospheric iodine chemistry.

Iodic acid (IA) particles are frequently observed in the upper troposphere and lower stratosphere (UTLS), yet their formation mechanism remains unclear. Nitric acid (NA) and ammonia (NH3) are key nucleation precursors in the UTLS. This study investigates the IA–NA–NH3 system using a theoretical approach. Our proposed nucleation mechanism highlights the crucial role of NA in IA nucleation, providing molecular-level evidence for the missing sources of IA particles in the UTLS.

Abundant chlorine-containing oxygenated organic molecules (Cl-OOMs) were formed from the reactions between Cl atoms and aromatics, and Cl-addition was identified as a non-negligible pathway for the formation of Cl-OOMs. Furthermore, many ambient Cl-OOMs potentially derived from Cl atoms and aromatics were measured in suburban Shanghai and most of them have adverse health effects. These findings provide critical insights into the formation mechanisms of Cl-OOMs in polluted settings.

This study provides insight into how individual ions measured by proton-transfer-reaction (PTR) mass spectrometry are produced by multiple volatile organic compounds (VOCs). A reference table is provided for attributing the PTR signal to contributing VOC species. The signals are grouped according to the complexity of their potential identities. We find that a number of signal ions such as C6H7+ for benzene and C5H9+ for isoprene merely give an upper limit of their corresponding concentrations.

The concept of the mean free path is fundamentally important to aerosol studies. Recent studies suggest that the mean free path of air (λair) could have been significantly overestimated by a factor of ~2. Here we show that this potential overestimation does not directly affect collision-induced aerosol dynamics in atmospheric conditions without high excess latent heat, while a similar influence of the mean free path of vapor (λ) on aerosol dynamics has been accounted for in current studies.

We considered two potential influencing factors of heavy-duty diesel vehicle emissions that are rarely mentioned in the literature: cumulative mileage and ambient temperatures. The results suggest that prolonged use of heavy-duty diesel vehicles and low ambient temperatures leads to reduced engine combustion efficiency, which in turn increases tailpipe emissions significantly.

This study examines new particle formation (NPF) in the Bolivian Andes at Chacaltaya mountain (CHC) and the urban El Alto–La Paz area (EAC). Days are clustered into four categories based on NPF intensity. Differences in particle size, precursor gases, and pollution levels are found. High NPF intensities increased Aitken mode particle concentrations at both sites, while volcanic influence selectively diminished NPF intensity at CHC but not EAC. This study highlights NPF dynamics in the Andes.

Online Vocus-PTR measurements show the compositions and seasonal variations in organic vapors in urban Beijing. With enhanced sensitivity and mass resolution, various species at a level of sub-parts per trillion (ppt) and organics with multiple oxygens (≥ 3) were observed. The fast photooxidation process in summer leads to an increase in both concentration and proportion of organics with multiple oxygens, while, in other seasons, the variations in them could be influenced by mixed sources.

The formation and evolution mechanisms of aromatics-derived highly oxygenated organic molecules (HOMs) are essential to understand the formation of secondary organic aerosol pollution. Our conclusion highlights an underappreciated formation pathway of aromatics-derived HOMs and elucidates detailed formation mechanisms of certain HOMs, which advances our understanding of HOMs and potentially explains the existing gap between model prediction and ambient measurement of the HOMs' concentrations.

The nucleation of iodic acid (HIO3) and iodous acid (HIO2) was proven to be critical in marine areas. However, HIO3–HIO2 nucleation cannot effectively derive the rapid nucleation in some polluted coasts. We find a significant enhancement of dimethylamine (DMA) on the HIO3–HIO2 nucleation in marine and polar regions with abundant DMA sources, which may establish reasonable connections between the HIO3–HIO2 nucleation and the rapid formation of new particles in polluted marine and polar regions.

Iodic acid (HIO3) nucleates with iodous acid (HIO2) efficiently in marine areas; however, whether methanesulfonic acid (MSA) can synergistically participate in the HIO3–HIO2-based nucleation is unclear. We provide molecular-level evidence that MSA can efficiently promote the formation of HIO3–HIO2-based clusters using a theoretical approach. The proposed MSA-enhanced iodine nucleation mechanism may help us to deeply understand marine new particle formation events with bursts of iodine particles.

Atmospheric new particle formation (NPF), together with secondary production of particulate matter in the atmosphere, dominates aerosol particle number concentrations and submicron particle mass loads in many environments globally. In this opinion paper, we describe the paradigm shift to understand NPF in a continuous way instead of using traditional binary event–non-event analysis.

By combining field measurements, simulations and recent chamber experiments, we investigate new particle formation (NPF) and growth in the Po Valley, where both haze and frequent NPF occur. Our results show that sulfuric acid, ammonia and amines are the dominant NPF precursors there. A high NPF rate and a lower condensation sink lead to a greater survival probability for newly formed particles, highlighting the importance of gas-to-particle conversion for aerosol concentrations.

Near-continuous measurements show the composition, sources, and seasonal variations of ultrafine particles (UFPs) in urban Beijing. Vehicle and cooking emissions and new particle formation are the main sources of UFPs, and aqueous/heterogeneous processes increase UFP mode diameters. UFPs are the highest in winter due to the highest primary particle emission rates and new particle formation rates, and CHO fractions are the highest in summer due to the strongest photooxidation.

Dust is a major source of atmospheric aerosols. Its chemical composition is often assumed to be similar to the parent soil. However, this assumption has not been rigorously verified. Dust aerosols are mainly generated by wind erosion, which may have some chemical selectivity. Mn, Cd and Pb were found to be highly enriched in fine-dust (PM2.5) aerosols. In addition, estimation of heavy metal emissions from dust generation by air quality models may have errors without using proper dust profiles.

New particle formation is an important source of atmospheric particles, exerting critical influences on global climate. Numerical models are vital tools to understanding atmospheric particle evolution, which, however, suffer from large biases in simulating particle numbers. Here we improve the model chemical processes governing particle sizes and compositions. The improved model reveals substantial contributions of newly formed particles to climate through effects on cloud condensation nuclei.

We set up a new parameterization for 1.4 nm particle formation rates from sulfuric acid–dimethylamine (SA–DMA) nucleation, fully including the effects of coagulation scavenging and cluster stability. Incorporating the new parameterization into 3-D chemical transport models, we achieved better consistencies between simulation results and observation data. This new parameterization provides new insights into atmospheric nucleation simulations and its effects on atmospheric pollution or health.

New particle formation and growth in polluted environments are not fully understood despite intensive research. We applied a cluster dynamics–multicomponent sectional model to simulate the new particle formation events observed in Beijing, China. The simulation approximately captures how the events evolve. Further diagnosis shows that the oxygenated organic molecules may have been under-detected, and modulating their abundance leads to significantly improved simulation–observation agreement.

We discuss and show the viability of a method where multiple isotopically labelled precursors are used for probing the formation pathways of highly oxygenated organic molecules (HOMs) from the oxidation of the monoterpene a-pinene. HOMs are very important for secondary organic aerosol (SOA) formation in forested regions, and monoterpenes are the single largest source of SOA globally. The fast reactions forming HOMs have thus far remained elusive despite considerable efforts over the last decade.

Based on a field campaign in a suburban area of Shanghai during summer 2021, we calculated formaldehyde (HCHO) production rates from 24 volatile organic compounds (VOCs). In addition, HCHO photolysis, reactions with OH radicals, and dry deposition were considered for the estimation of HCHO loss rates. Our results reveal the key precursors of HCHO and suggest that HCHO wet deposition may be an important loss term on cloudy and rainy days, which needs to be further investigated.

We compare observed survival probabilities of atmospheric particles from Beijing, China, with survival probabilities based on analytical formulae and model simulations. We find observed survival probabilities under polluted conditions at smaller sizes to be higher, while at larger sizes they are lower than or similar to theoretical survival probabilities. Uncertainties in condensation sink and growth rate are unlikely to explain higher-than-predicted survival probabilities at smaller sizes.

The survival probability of new particles is the key parameter governing their influences on the atmosphere and climate, yet the knowledge of particle survival in the atmosphere is rather limited. We propose methods to compute the size-resolved particle survival probability and validate them using simulations and measurements from diverse environments. Using these methods, we could explain particle survival from the cluster size to the cloud condensation nuclei size.

Atmospheric new particle formation (NPF) is a dominant source of atmospheric ultrafine particles. In urban environments, traffic emissions are a major source of primary pollutants, but their contribution to NPF remains under debate. During the COVID-19 lockdown, traffic emissions were significantly reduced, providing a unique chance to examine their relevance to NPF. Based on our comprehensive measurements, we demonstrate that traffic emissions alone are not able to explain the NPF in Beijing.

Sensitivity cases demonstrated the significant contributions of CPM emissions from stationary combustion and mobile sources to primary, secondary, and total OA concentrations.

The influences of new particle formation on the climate and air quality are governed by particle survival, which has been under debate due to uncertainties in the coagulation sink. Here we measure the coagulation coefficient of sub-10 nm particles and demonstrate that collisions between the freshly nucleated and background particles can effectively lead to coagulation. We further show that the effective coagulation sink is consistent with the new particle formation measured in urban Beijing.

Gaseous oxygenated organic molecules (OOMs) are able to form atmospheric aerosols, which will impact on human health and climate change. Here, we find that OOMs in urban Beijing are dominated by anthropogenic sources, i.e. aromatic (29 %–41 %) and aliphatic (26 %–41 %) OOMs. They are also the main contributors to the condensational growth of secondary organic aerosols (SOAs). Therefore, the restriction on anthropogenic VOCs is crucial for the reduction of SOAs and haze formation.

Both CO2 and carbonate salt work as the precursor of carbonate radicals, which largely promotes sulfate formation during the daytime. This study provides the first indication that the carbonate radical not only plays a role as an intermediate in tropospheric anion chemistry but also as a strong oxidant for the surface processing of trace gas in the atmosphere. CO2, carbponate radicals, and sulfate receive attention from those looking at the environment, atmosphere, aerosol, and photochemistry.

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.

We observed significant concentrations of gaseous HBr and HCl throughout the winter and springtime in urban Beijing, China. Our results indicate that gaseous HCl and HBr are most likely originated from anthropogenic emissions such as burning activities, and the gas–aerosol partitioning may play a crucial role in contributing to the gaseous HCl and HBr. These observations suggest that there is an important recycling pathway of halogen species in inland megacities.

Short summary
Based on observed atmospheric new particle formation events at multiple sites in eastern China, we find that sulfuric acid and dimethylamine can explain the observed atmospheric nucleation and the differences in the nucleation intensity among campaigns can be largely attributed to temperature and precursor concentrations. Our results also show that oxygenated organic molecules can make a great contribution to the initial growth of freshly nucleated particles in the real atmosphere.
