This study evaluated the PM2.5 simulation by the latest Community Regional Atmospheric Chemistry Multiphase Mechanism (CRACMM) mechanism coupled with the Community Multiscale Air Quality (CMAQ) model, covering different seasons and specific regions over China. Modelling results derived by CRACMM are compared with two well-established chemical mechanisms. The research findings provide a solid foundation for the further application of CRACMM in understanding and regulating air pollution globally.

Mineral dust impacts climate and air quality, varying by composition. This study examined its effects on radiation and pollution during a North China dust storm using WRF-CHIMERE and three dust atlases. Bulk dust had a shortwave radiative forcing of -5.72 W/m², while mineral-specific effects increased it by +0.10 W/m². Aerosol-radiation interactions raised PM₁₀ to 1189.48 μg/m³. Accurate mineral data is essential for improving dust-related climate and air quality simulations.

Oxygenated volatile organic compounds (OVOCs) are important ozone (O3) precursors. However, most O3 formation analysis based on the box model (OBM) does not include any OVOC constraint. To access the interference of OVOCs with O3 simulation, this study presents results from a field campaign and OBM analysis. Our results indicate that no OVOC constraint in the OBM can lead to overestimation of OVOCs, free radicals, and O3.

Ground-level ozone pollution has emerged as a significant air pollutant in China. Chemical transport models (CTMs) serve as crucial tools in addressing ozone pollution. This study reviews CTM applications for simulating ozone in China and proposes goal and criteria benchmark values for evaluating ozone. Along with prior work on PM₂₅ and other pollutants, this effort establishes a comprehensive framework for evaluating CTM performance in China.

Surface ozone concentrations have emerged as a major environmental issue in China. Although control strategies aimed at reducing NOx emissions from conventional combustion sources are widely recognized, soil NOx emissions have received little attention. The impact of soil NO emissions on ground-level ozone concentration is yet to be evaluated. In this study, we estimated the soil NO emissions and evaluated its impact on ozone formation in China.

Molecular markers in organic aerosol (OA) provide specific source information on PM2.5, and the contribution of cooking emissions to OA is significant, especially in urban environments. This study investigates the variation in concentrations and oxidative degradation of fatty acids and corresponding oxidation products in ambient air, which can be a guide for the refinement of aerosol source apportionment and provide scientific support for the development of emission source control policies.

Secondary organic aerosols are an important component of PM2.5, with contributions from anthropogenic, biogenic volatile organic compounds, semi- and intermediate volatility organic compounds. Policy makers need to know which SOA precursors are important. We investigated the role of different SOA precursors and SOA algorithms by applying two commonly used models, CAMx and CMAQ. Suggestions for SOA modelling and control are provided.

A significant increase in O3 concentrations was found during the lockdown period of COVID-19 in most areas of China. By field measurements coupled with machine learning, an observation-based model (OBM) and sensitivity analysis, we found the changes in the NOx / VOC ratio were a key reason for the significant rise in O3. To restrain O3 pollution, more efforts should be devoted to the control of anthropogenic OVOCs, alkenes and aromatics.

Gas-phase chemical mechanisms are key components of air quality models used by regulatory agencies for air quality and public health planning. We use modeled ozone concentrations and Ozone Production Efficiency (OPE) to compare four chemical mechanisms and find that OPE is a viable comparison metric under atmospheric conditions where nitrogen oxides are limited. Using OPE to predict how ozone responds to emissions reductions, however, is an oversimplification that can overstate ozone reductions.

Anhydro-saccharides are key organic markers for biomass burning, but their decay rates and driving factors in real ambient environments remain unclear. This study conducted an online field measurement of PM₂.₅-bound saccharides in three eastern Chinese cities. Daytime levoglucosan decay rates were calculated, and the driving factors were investigated using a machine learning model. Findings of this study offers a strong scientific basis to support air pollution management.

Despite growing use of machine learning in environmental research, few have studied how input data affects findings. We examined the impact of input data characteristics on nitrogen deposition estimates in East and Southeast Asia. Insufficient sample size cuts accuracy by up to 12 %, while data-scarce and remote areas show up to 50 % bias due to poor training data representation. We created a transferable framework for uncertainty quantification, applicable to other data-scarce geospatial tasks.

This study indicates that using HFO‑1234ze(E) as a medical propellant in pressurized metered dose inhalers (pMDIs) reduces environmental impact compared with current propellants, and that associated trifluoroacetic acid (TFA) formation levels are predicted to be significantly below all reported safety thresholds. The results suggest this next‑generation propellant supports climate goals with its near‑zero global warming potential (GWP) and offers a sustainable substitute, helping ensure future pMDI supply for people with chronic respiratory diseases.

Despite the crucial role of halogen radicals in the atmosphere, current chemical transport models (CTMs) do not account for multi-phase halogen processes. To address this issue, we incorporated 177 halogen reactions, together with anthropogenic and natural halogen emissions into the CTMs. Our findings reveal that incorporation of these halogen processes significantly improves model performances compared to observations. In addition, we emphasize the influence of halogen radicals on air quality.

We incorporated each HONO process into the current CMAQ modeling framework to enhance the accuracy of HONO mixing ratio predictions. These results expand our understanding of HONO photochemistry and identify crucial sources of HONO that impact the total HONO budget in Seoul, South Korea. Through this investigation, we contribute to resolving discrepancies in understanding chemical transport models, with implications for better air quality management and environmental protection in the region.

We describe the Comprehensive Air quality Model with extensions (CAMx) and evaluate a model simulation during 2016 over nine U.S. climate zones. For ozone, the model statistically replicates measured concentrations better than most other past models and applications. For small inhalable particulates, the model replicates concentrations consistent with most other past models and applications subject to common uncertainties associated with sources, weather, and chemical interactions.

NO2 is a gas with implications for air pollution. A campaign conducted in Houston provided an opportunity to compare NO2 from different instruments and a model. Aircraft and satellite observations agreed well with measurements on the ground; however, the latter estimated lower values. We find that model-simulated NO2 was lower than observations, especially downtown, suggesting that NO2 sources associated with the urban core of Houston, such as vehicle emissions, may be underestimated.

TROPOMI measurements offer a valuable means to validate emissions inventories and ozone formation regimes, with important limitations. Lightning NOx is important to account for in Texas and can contribute up to 24 % of the column NO2 in rural areas and 8 % in urban areas. Modeled NO2 in urban areas agrees with TROPOMI NO2 to within 20 % in most circumstances, with a small underestimate in Dallas (−13 %) and Houston (−20 %). Near Texas power plants, the satellite appears to underrepresent NO2.

Short summary
Secondary organic aerosol (SOA) constitutes a major component of atmospheric aerosol that models must account for to assess how human activities influence air quality, climate, and public health. We find substantial differences in how current air quality models represent SOA highlighting a lack of consensus within the modelling community. Our findings emphasize the need to recognize the limitations of current SOA schemes in the context of air quality management and policy development.
