We present the OH and HO2 radical observations at the Shenzhen site (Pearl River Delta, China) in the autumn of 2018. The diurnal maxima were 4.5 × 106 cm−3 for OH and 4.2 × 108 cm−3 for HO2 (including an estimated interference of 23 %–28 % from RO2 radicals during the daytime). The OH underestimation was identified again, and it was attributable to the missing OH sources. HO2 heterogeneous uptake, ROx sources and sinks, and the atmospheric oxidation capacity were evaluated as well.

We investigated the photooxidation of isoprene in the presence of water. We found that water enhanced the formation of methacrolein and methyl vinyl ketone in the first-generation reactions by changing the structures of the reaction intermediates and raised formic acid and acetic acid yields considerably in the multi-generation reactions. The results of this study help understand the fate of isoprene in the atmosphere and improve the effect of the atmospheric simulations.

The immersion ice nucleation effectiveness of aerosols from multiple sources in the urban environment remains elusive. In this study, we demonstrate that the immersion ice-nucleating particle (INP) concentration increased dramatically during a dust event in an urban atmosphere. Pollutant aerosols, including inorganic salts formed through secondary transformation (SIA) and black carbon (BC), might not act as effective INPs under mixed-phase cloud conditions.

This work characterized the spatial variabilities of air pollutants in a megacity by advanced mobile measurements. The results show a large spatial heterogeneity in the distributions of PM2.5 composition and volatile organic compounds under non-haze conditions, and relatively uniform spatial distributions under haze conditions that may indicate a chemical homogeneity on an intracity scale. The findings improve our understanding of urban air pollution.

This paper presents the first OH and HO2 radical observations made in the Yangtze River Delta in China, and strong oxidation capacity is discovered based on direct measurements. The impacts of new OH regeneration mechanisms, monoterpene oxidation, and HO2 uptake processes are examined and discussed. The sources and the factors to sustain such strong oxidation are the key to understanding the ozone pollution formed in this area.

The gas–particle partitioning process of glyoxal and methylglyoxal could contribute to secondary organic aerosol formation. Here, we launched five observations in different seasons and simultaneously measured glyoxal and methylglyoxal in the gas and particle phases. Compared to reversible pathways, irreversible pathways played a dominant role with a proportion of more than 90 % in the ambient atmosphere, and the proportion was influenced by relative humidity and inorganic components in aerosols.

We present a feasible instrument for the measurement of NO2, total peroxy nitrates (PNs, RO2NO2), and total alkyl nitrates (ANs, RONO2) in the atmosphere. The instrument samples sequentially from three channels at different temperature settings and then measures spectra using one cavity-enhanced absorption spectrometer. The concentrations are determined by spectral fitting and corrected using the lookup table method conveniently. The instrument will promote the study of PNs and ANs.

Nitrated phenols (NPs) are crucial components of brown carbon. To comprehend the constitutes and sources of NPs in winter of Beijing, their concentrations were measured by a CI-LToF-MS. The secondary formation process was simulated by a box model. NPs were mainly influenced by primary emissions and regional transport. Primary emitted phenol rather than benzene oxidation was crucial in the heavy pollution episode in Beijing. This provides more insight into pollution control strategies of NPs.

Due to their lower diffusion capacities and higher conversion capacities, urban areas in Xi’an experienced severe ozone pollution in the summer. In this study, a campaign of comprehensive field observations and VOC grid sampling was conducted in Xi’an from 20 June to 20 July 2019. We found that Xi'an has a strong local emission source of VOCs, and vehicle exhaust was the primary VOC source. In addition, alkenes, aromatics, and oxygenated VOCs played a dominant role in secondary transformations.

We performed chassis dynamometer experiments to investigate the emissions and secondary organic aerosol (SOA) formation potential of intermediate volatility organic compounds (IVOCs) from an on-road Chinese gasoline vehicle. High IVOC emission factors (EFs) and distinct volatility distribution were recognized. Our results indicate that vehicular IVOCs contribute significantly to SOA, implying the importance of reducing IVOCs when making air pollution control policies in urban areas of China.

Stabilized Criegee intermediates (SCIs) are important factors in estimating aerosol formation in the atmosphere. Here the results show that SCIs account for more than 60 % of aerosol formation in limonene ozonolysis and water is an uncertainty in SCI performances. The aerosol formation potential of SCIs under high-humidity conditions is double that under dry and low-humidity conditions, suggesting SCI reactions are still important in contributing to aerosols at high relative humidity.

In this study we evaluated the model performances for simulating secondary inorganic aerosol (SIA) and organic aerosol (OA) in PM2.5 in China against comprehensive datasets. The potential biases from factors related to meteorology, emission, chemistry, and atmospheric removal are systematically investigated. This study provides a comprehensive understanding of modeling PM2.5, which is important for studies on the effectiveness of emission control strategies.

In limonene ozonolysis, the endocyclic double bond is inclined to generate hydroxy radicals, while the exocyclic double bond has a higher fraction of forming stabilized Criegee intermediates. The oxidation that happens on the exocyclic double bond greatly contributes to the organic peroxides, which account for a considerable proportion of secondary organic aerosol. Terpenes with multiple double bonds may have more complex effects on the atmosphere than previously thought.

Comparison of modeled and measured peroxide concentrations at a rural site in the summer North China Plain demonstrated an underestimation during biomass burning events and an overestimation on haze days, which were related to the direct production of peroxides from biomass burning and the heterogeneous uptake of peroxides by aerosols, respectively. Our findings are of great significance for comprehensively understanding the chemical budget of atmospheric peroxides in detail.

The formation, gas-particle partitioning, and evolution of atmospheric organic peroxides are unclear. We investigated the ozonolysis of α-pinene, and focused on peroxides. We found that gas-particle partitioning coefficients of peroxides are much higher than the values from our theoretical prediction, and some gaseous peroxides undergo rapid heterogeneous decomposition on SOA particles in the presence of water vapor, resulting in the additional production of hydrogen peroxide.

The present study provides the first measurement for the uptake coefficient of gaseous peroxide compounds including peroxyacetic acid and hydrogen peroxide on the ambient particles (PM2.5 and Asian Storm Dust) over a wide range of relative humidity. The measured uptake coefficient values suggest that the heterogeneous reaction on the ambient particles plays an important role in the atmospheric budgets of peroxide compounds and potentially affects the components of aerosols in the atmosphere.

The present field measurements have provided strong evidence for the existence of peroxyformic acid (HC(O)OOH) in the atmosphere for the first time. Moreover, the potential impact of peroxyformic acid chemistry on the formic acid production and the radical budget has been evaluated on the basis of model calculations. Our findings are of importance for a full understanding of the cycling of oxidants and the source of organic acids in the atmosphere.

Bromine monoxide (BrO) strongly affects atmospheric chemistry in the springtime Arctic, yet there are still many uncertainties around its sources and recycling, particularly in the context of a rapidly changing Arctic. In this study, we observed BrO as a function of altitude above the Alaskan Arctic. We found that BrO was often most concentrated near the ground, confirming the ability of snow to produce and recycle reactive bromine, and identified four common vertical distributions of BrO.

During the CoMet mission in the Upper Silesian Coal Basin (USCB) ground-based and airborne air samples were taken and analyzed for the isotopic composition of CH4 to derive the mean signature of the USCB and source signatures of individual coal mines. Using δ2H signatures, the biogenic emissions from the USCB account for 15 %–50 % of total emissions, which is underestimated in common emission inventories. This demonstrates the importance of δ2H-CH4 observations for methane source apportionment.

In this study, combining comprehensive field measurements and a box model, we found NO2 conversion on the ground surface was the most important source for HONO production among the proposed heterogeneous and gas-phase HONO sources. In addition, HONO was found to evidently enhance O3 production and aggravate O3 pollution in summer in China. Our study improved our understanding of the relative importance of different HONO sources and the crucial role of HONO in O3 formation in polluted areas.

This study provides the first estimate of high rates of formic acid (HCOOH) production from the photochemical aging of real ambient particles and demonstrates the potential importance of this pathway in the formation of HCOOH under ambient conditions. Incorporating this pathway significantly improved the performance of a widely used chemical model. Our solution irradiation experiments demonstrated the importance of nitrate photolysis in HCOOH production via the production of oxidants.

The study employed total ozone reactivity to demonstrate how emissions of Norway spruce readily react with ozone and could be a major ozone sink, particularly under stress. Additionally, this approach provided insight into the limitations of current analytical techniques that measure the compounds present or emitted into the atmosphere. The study shows how the technique used was not enough to measure all compounds emitted, and this could potentially underestimate various atmospheric processes.

In this study, we present the partitioning of CO2 signals from biogenic, petroleum and natural gas sources by combining CO, 13CO2 and 14CO2 measurements. Using measurements from flask air samples at three sites in the greater Los Angeles region, we find larger and positive contributions of biogenic signals in winter and smaller and negative contributions in summer. The largest contribution of natural gas combustion generally occurs in summer.

Measurements of OH, HO2 and RO2 radicals and also OH reactivity were made at a UK coastal site and compared to calculations from a constrained box model utilising the Master Chemical Mechanism. The model agreement displayed a strong dependence on the NO concentration. An experimental budget analysis for OH, HO2, RO2 and total ROx demonstrated significant imbalances between HO2 and RO2 production rates. Ozone production rates were calculated from measured radicals and compared to modelled values.

This study provides ground-observational evidence that supports earlier suggestions that savanna fires are the main emitters and modulators of carbon monoxide gas in Africa. Using isotope-based techniques, the study has shown that about two-thirds of this gas is emitted from savanna fires, while for urban areas, in this case Nairobi, primary sources approach 100 %. The latter has implications for air quality policy, suggesting primary emissions such as traffic should be targeted.

NOx is a precursor to hazardous tropospheric ozone and can be emitted from various anthropogenic sources. It is important to quantify NOx emissions in urban environments to improve the local air quality, which still remains a challenge, as sources are heterogeneous in space and time. In this study, we calculate NOx emissions over Los Angeles, based on aircraft measurements in June 2021, and compare them to a local emission inventory, which we find mostly overpredicts the measured values.

Highly oxygenated organic molecules (HOMs) form secondary organic aerosol that affects air quality and health. In this study, we demonstrate that in a moderately polluted city with abundant vegetation, the composition of HOMs is largely controlled by the effect of NOx on the biogenic volatile organic compound oxidation. Comparing the results from two nearby stations, we show that HOM composition and formation pathways can change considerably within small distances in urban environments.

Surface ozone is a pollutant regulated for public health. This study derived surface ozone trends over South Korea from 2001 to 2021 and highlighted that South Korea has been a nonattainment area since 2010, based on the US EPA standard. However, the occurrences of high ozone condition decreased in spring during the COVID-19 pandemic, partly due to large reductions of ozone precursor concentrations in China and South Korea.

This is the first report of ship-emitted nitrogen stable isotope composition (δ15N) of nitrogen oxides (NOx). The results showed that δ15N–NOx from ships was −18.5 ± 10.9 ‰ and increased monotonically with tightening emission regulations. The selective catalytic reduction system was the most vital factor. The temporal variation in δ15N–NOx was evaluated and can be used to select suitable δ15N–NOx for a more accurate assessment of the contribution of ship-emitted exhaust to atmospheric NOx.

The San Joaquin Valley is an agricultural area with poor air quality. Organic gases drive the formation of hazardous air pollutants. Agricultural emissions of these gases are not well understood and have rarely been quantified at landscape scale. By combining aircraft-based emission measurements with land cover information, we found mis- or unrepresented emission sources. Our results help in understanding of pollution sources and in improving predictions of air quality in agricultural regions.

Particle uptakes of HCHO and the impacts on PM2.5 and O3 production remain highly uncertain. Based on the investigation of co-occurring wintertime O3 and PM2.5 pollution in a coastal city of southeast China, we found enhanced heterogeneous formation of hydroxymethanesulfonate (HMS) and increased ROx concentrations and net O3 production rates. The findings of this study are helpful to better explore the mechanisms of key precursors for co-occurring PM2.5 and O3 pollution.

In this study, we quantify CH4 emissions from onshore oil production sites in Romania at source and facility level using a combination of ground- and drone-based measurement techniques. We show that the total CH4 emissions in our studied areas are much higher than the emissions reported to UNFCCC, and up to three-quarters of the detected emissions are related to operational venting. Our results suggest that oil and gas production infrastructure in Romania holds a massive mitigation potential.

Online volatile organic compound (VOC) measurements by gas chromatography–mass spectrometry, with other O3 precursors, were used to identify key VOC and other key sources in Lhasa. Total VOCs (TVOCs), alkanes, and aromatics are half as abundant as in Beijing. Oxygenated VOCs (OVOCs) consist of 52 % of the TVOCs. Alkenes and OVOCs account for 80 % of the ozone formation potential. Aromatics dominate secondary organic aerosol potential. Positive matrix factorization decomposed residential sources.

The hydroxyl (OH), hydroperoxy (HO2), and organic peroxy (RO2) radicals play important roles in atmospheric chemistry and have significant air quality implications. Here, we compare measurements of OH, HO2, and total peroxy radicals (XO2) made in a remote forest in Michigan, USA, to predictions from a series of chemical models. Lower measured radical concentrations suggest that the models may be missing an important radical sink and overestimating the rate of ozone production in this forest.

The recorded spatial and temporal variability of TBECH suggest that the release from imported consumer products containing TBECH is the most likely explanation for its environmental occurrence in Canada.

A primary sink of air pollutants is dry deposition. Dry deposition estimates differ across the models used to simulate atmospheric chemistry. Here, we introduce an effort to examine dry deposition schemes from atmospheric chemistry models. We provide our approach’s rationale, document the schemes, and describe datasets used to drive and evaluate the schemes. We also launch the analysis of results by evaluating against observations and identifying the processes leading to model–model differences.

Nitrogen oxide (NOx) is a hazardous air pollutant, and it is the precursor of short-lived climate forcers like tropospheric ozone and aerosol particles. While NOx emissions from transportation has been strictly regulated, soil NOx emissions are overlooked. We use the airborne flux measurements to observe NOx emissions from highways and urban and cultivated soil land cover types. We show non-negligible soil NOx emissions, which are significantly underestimated in current model simulations.

Based on atmospheric HFC-23 observations, the first estimate of post-CDM HFC-23 emissions in eastern Asia for 2008–2019 shows that these emissions contribute significantly to the global emissions rise. The observation-derived emissions were much larger than the bottom-up estimates expected to approach zero after 2015 due to national abatement activities. These discrepancies could be attributed to unsuccessful factory-level HFC-23 abatement and inaccurate quantification of emission reductions.

We study the interhemispheric gradient of sulfur hexafluoride (SF6), a strong long-lived greenhouse gas. Its emissions are stronger in the northern hemisphere, therefore mixing ratios in the southern hemisphere lag behind. Comparing the observations to results from a box model, the model predicts air in the southern hemisphere to be older. For a better agreement, the emissions used as model input need to be increased, their spatial pattern changed, and we need to modify north-south transport.

We investigated surface ozone variability at East Antarctica based on the measurements and EMAC global model simulations during austral summer. Nearly half of the surface ozone is found to be of stratospheric origin. The east coast of Antarctica acts as a stronger sink of ozone than surrounding regions. Photochemical loss of ozone is counterbalanced by downward transport of ozone. Study highlights intertwined role of chemistry and dynamics in governing the ozone variations over East Antarctica.

Many works reported NO3 chemistry in inland regions, while less targeted marine regions. We measured N2O5 and related species on a typical island and found intensive nighttime chemistry and rapid NO3 loss. NO contributed significantly to NO3 loss despite the sub-ppbv level, suggesting nocturnal NO3 reactions would be largely enhanced once without NO emission in the open ocean. This highlights the strong influences of urban outflow on downward marine areas in terms of nighttime chemistry.

In the present work, we make a compilation to understand the historical trends and estimate the atmospheric half-life of each compound. Of the compounds studied, HCB was the only one that showed no clear trend, while the rest of the studied compounds showed a significant decrease over time. This is consistent with results for polar and sub-polar zones.

Shanxi accounts for 10 % of the world’s coal production. This work computes CH4 emissions and uncertainty on a mine-by-mine basis, including underground, overground, and abandoned. This work uses a flux tower to observe and calculate emissions at one mine over 4 months. The half-hour variability and bias correction are propagated over the emissions dataset. Comparisons show the emissions are higher where mines are located, and regions with significant emissions but no mines are identified.

We also analyzed the regional characteristics of CH4 at each KMA station. CH4 levels measured at KMA stations are compared to those measured at other Asian stations. From the long-term records of CH4 and δ13CH4 at AMY, we confirmed that the source of CH4xs changed from the past (2006 to 2010) to recent (2016 to 2020) years in East Asia.

We describe the first data retrieval from a newly installed instrument providing measurements of vertical profiles of air pollution over Central London during heatwaves in summer 2022. We use these observations with surface air quality network measurements to support interpretation that an exponential increase in biogenic emissions of isoprene during heatwaves provides the limiting ingredient for severe ozone pollution, leading to non-compliance with the national ozone air quality standard.

This study investigates the link between weather regimes and atmospheric composition at a Pyrenean observatory. Five years of meteorological data were synchronized on a daily basis, then, using a clustering method, separated into 6 groups of observation days, most of them showing marked characteristics of different weather regimes (fair and disturbed weather, winter windstorms, foehn). Statistical differences in gas and particle concentrations appeared between the groups, and were discussed.

We present OH observation and model simulation results at a coastal site in Hong Kong. The model predicted the OH concentration under high-NOx well but overpredicted it under low-NOx conditions. This implies an insufficient understanding of OH chemistry under low-NOx conditions. We show evidence of missing OH sinks as a possible cause of the overprediction.

A near-complete speciation of reactive organic gases from residential combustion was developed to get more insights into their atmospheric effects. Oxygenated species, higher hydrocarbons and nitrogen-containing species played larger roles in these emissions compared with common hydrocarbons. Based on the near-complete speciation, these emissions were largely underestimated, leading to more underestimation of their hydroxyl radical reactivity and secondary organic aerosol formation potential.

Comprehensive observations of HOx radicals were conducted at a coastal site in the Pearl River Delta. Radical chemistry was time-varyingly influenced by different air masses. Land mass (LAM) promotes a more active photochemical process, with daily averages of 7.1 × 106 cm−3 and 5.2 × 108 cm−3 for OH and HO2, respectively. The rapid oxidation process was accompanied by a higher diurnal HONO concentration, which influences the ozone-sensitive system and eventually magnifies the ozone background.

The Palau Atmospheric Observatory is introduced as an ideal site to detect changes in atmospheric composition and dynamics above the remote Tropical West Pacific. We focus on the ozone sounding program from 2016–2021, including El Nino 2016. The year-round high convective activity is reflected in dominant low tropospheric ozone and high relative humidity. The seasonal distribution of both constituents is unique compared to other tropical sites and modulated by the Intertropical Convergence Zone.

Hydrogen peroxide is a key contributor to the oxidative chemistry of the atmosphere through its link to the most prominent oxidants controlling its self-cleansing capacity, HOx. During the CAFE-Africa campaign, H2O2 was measured over the Atlantic Ocean and western Africa in August/September 2018. The study gives an overview of the distribution of H2O2 in the upper tropical troposphere and investigates the impact of convective processes in the Intertropical Convergence Zone on the budget of H2O2.

High RH could contribute to the secondary formation of HONO in the sea atmosphere. High temperature could promote the formation of HONO from NO2 heterogeneous reactions in the sea and coastal atmosphere. The aerosol surface plays a more important role during the above process in coastal and sea cases. The generation rate of HONO from the NO2 heterogeneous reaction in the sea cases is larger than that in inland cases in higher atmospheric layers above 600 m.

Ambient ion chemical composition measurements provide insight into trace gases that are precursors for the formation and growth of new aerosol particles. We use a new data analysis approach to increase the chemical information from these measurements. We analyze results from an agricultural region, a little studied land use type that is ~41 % of global land use, and find that the composition of gases important for aerosol formation and growth differs significantly from that in other ecosystems.

Atmospheric nitrous acid (HONO) amount fractions measured at Halley Research Station, Antarctica, were found to be low. Vertical fluxes of HONO from the snow were also measured and agree with the estimated HONO production rate from photolysis of snow nitrate. In a simple box model of HONO sources and sinks, there was good agreement between the measured flux and amount fraction. HONO was found to be an important OH radical source at Halley.

Atmospheric cluster ions are important constituents in the atmosphere. However, the quantitative research on their compositions is still limited, especially in urban environments. Here we demonstrate the feasibility of an in situ quantification method of cluster ions measured by a high-resolution mass spectrometer and reveal their governing factors, sources, and sinks in urban Beijing through quantitative analysis of cluster ions, reagent ions, neutral molecules, and condensation sink.

Short summary
In this study, we found that the effective field-derived Henry's law constant for the ground rainwater and the gas-phase H2O2 was about 2.5 times that of the theoretical value, and the effective gas–particle partitioning coefficient for the aerosol particle and the gas-phase H2O2 was 4 orders of magnitude higher than the theoretical one. We suggested the missing source of H2O2 in the particulate phase, e.g. the contribution from the decomposition/hydrolysis of organic peroxides.
In this study, we found that the effective field-derived Henry's law constant for the ground...
