Air pollution in China has shifted from particles to ozone as a main concern in warm-seasons. We combined ten years of observations with model simulations to explore how ozone and secondary particles change in the Guanzhong Basin. We find that chemical drivers shift during the season, leading to different pollution responses. These insights point to targeted, season-specific strategies that can improve air quality more effectively.

We compared fine particles collected in a city road tunnel with particles from controlled tests of gasoline vehicle exhaust. The exhaust samples reproduced the main chemical pattern in the tunnel but missed many chemicals containing sulfur and substances linked to tire wear. The results show that tailpipe exhaust alone cannot fully describe traffic pollution and that road wear and chemical changes near roads should also be considered.

This study examines how air pollution affects snowfall during a winter storm in central China. Using a detailed computer model of weather and air pollution, we compared conditions with different pollution levels. We find that pollution can either increase or decrease snowfall, depending on air moisture and whether snow forms mainly as ice or liquid. Pollution mainly changes how often snowfall occurs, rather than where it falls, improving understanding of weather and climate impacts.

This study examines the aerosol hygroscopicity and mixing state at Huashan (2060 m), a key free tropospheric site in central China. We find that hygroscopicity depends on particle size, source-related changes, and moisture-driven processing, which distinguishes this region from other high-altitude regions and may provide key constraints for aerosol-cloud and regional climate models.

This study examines how dust transport modulates oxalic acid formation pathways in aerosols across different elevations of Mount Hua. During dust events, oxalic acid and precursors shift from fine to coarse particles, with concurrent heterogeneous reactions on coarse particle surfaces. The characteristic isotopic fractionation signatures accompanying these transformations yield novel theoretical frameworks for elucidating aerosol aging mechanisms in mountainous environments.

This study investigated how cloud–radiation interactions influence ozone formation in a warming climate. Using measurements, reanalysis data, and models, we found that cloud–radiation interactions can worsen O3 pollution, and climate warming will amplify the influence. We highlight that climate change will pose greater challenges for China's O3 pollution prevention and control, and actions such as reducing O3 precursors emissions and mitigating climate change are urgently needed.

The impacts of agricultural fertilization on nitrogen oxide and air quality are becoming more pronounced with continuous reductions in fossil fuel sources in China. We report that atmospheric nitrogen dioxide pulses driven by agricultural fertilization largely complicate air pollution in the North China Plain, highlighting the necessity of agricultural emission control.

Our results demonstrate that the reduction in mass absorption efficiency from biomass burning is mainly driven by the decline in the imaginary part, with particle size playing a minor role. And light absorption of oxygenated brown carbon (BrC) increases significantly with aging, but hydrocarbon-like BrC decreases over time. These results emphasize the necessity to classify BrC into different groups based on their mass absorption efficiency and atmospheric behavior in climate models.

This study uses a cloud-resolving model to examine how aerosols influence a mesoscale convective system (MCS) in central China via aerosol–radiation interaction (ARI) and aerosol–cloud interaction (ACI). Without ARIs, added aerosols do not significantly affect precipitation due to cloud competition for moisture. ARIs can stabilize or enhance convection. High aerosol levels lead to a combined ARI and ACI effect that greatly reduces precipitation.

We studied wildfire carbon dioxide emissions across China from 2001 to 2022 and found that cropland and forest fires are the main contributors. While forest and shrub fires have decreased, cropland fires are rising, especially in northeastern China. Our findings suggest that climate and local policies affect wildfire emissions and that better fire management is needed to reduce future carbon impacts.

Brown carbon (BrC) is a type of airborne particle produced from various combustion sources which is light absorption. Historically, climate models have categorizing organic particles as either non-absorbing or purely reflective. Our study shows that BrC can reduce the usual cooling effect of organic particles. While BrC is often linked to biomass burning, however, BrC from fossil fuels contributes significantly to atmospheric heating.

Accurate NOx emission estimates are required to better understand air pollution. This study investigates and demonstrates the ability of the superposition column model in combination with TROPOMI tropospheric NO2 column data to estimate city-scale NOx emissions and lifetimes and their variabilities. The results of this work nevertheless confirm the strength of the superposition column model in estimating urban NOx emissions with reasonable accuracy.

We studied nitrogen-containing organic compounds (NOCs) in particulate matter <2.5 µm particles on the southeastern Tibetan Plateau. We found that biomass burning and transboundary transport are the main sources of NOCs in the high-altitude area. Understanding these aerosol sources informs how they add to regional and potentially global climate changes. Our findings could help shape effective environmental policies to enhance air quality and address climate impacts in this sensitive region.

A new long-term inversed emission inventory for Chinese air quality (CAQIEI) is developed in this study, which contains constrained monthly emissions of NOx, SO2, CO, PM2.5, PM10, and NMVOCs in China from 2013 to 2020 with a horizontal resolution of 15 km. Emissions of different air pollutants and their changes during 2013–2020 were investigated and compared with previous emission inventories, which sheds new light on the complex variations of air pollutant emissions in China.

The Tibetan Plateau has a unique geographical location, but there is a lack of detailed research on the real-time characteristics of full aerosol composition. This study elaborates the changes in chemical characteristics between transport and local fine particles during the pre-monsoon, reveals the size distribution and the mixing states of different individual particles, and highlights the contributions of photooxidation and aqueous reaction to the formation of the secondary species.

PM2.5 pollution still frequently occurs in northern China during winter, and it is necessary to figure out the causes of air pollution based on intensive real-time measurement. The findings elaborate the chemical characteristics and source contributions of PM2.5 in three pilot cities, reveal potential formation mechanisms of secondary aerosols, and highlight the importance of controlling biomass burning and inhibiting generation of secondary aerosol for air quality improvement.

We investigated the light absorption properties of brown carbon (BrC) in the Tibetan Plateau (TP). BrC made a substantial contribution to the submicron aerosol absorption, which is related to the cross-border transport of biomass burning emission and secondary aerosol from Southeast Asia. The radiative effect of BrC was half that of black carbon, which can remarkably affect the radiative balance of the TP.

We identified the brown carbon (BrC) molecules and their absorbing abilities on a molecular level from animal dung fuel combustion over the Tibetan Plateau region in China. The ultra-high performance liquid chromatography quadrupole time-of-flight mass spectrometer coupled with the partial least squares regression were precisely applied to characterize the molecular absorptions, key molecular markers, and radiative effects of BrC from household combustion scenarios at the high-altitude area.

In this study, we report the long-term measurement of organic carbon (OC) and elementary carbon (EC) in PM2.5 with hourly time resolution conducted at a regional site in Shanghai from 2016 to 2020. The results from this study provide critical information about the long-term trend of carbonaceous aerosol, in particular secondary OC, in one of the largest megacities in the world and are helpful for developing pollution control measures from a long-term planning perspective.

Atmospheric motions play an important role in the mass concentration and the direct radiative effect (DRE) of black carbon (BC). The finding from this study elaborated the impacts of different scales of atmospheric motion on source-specific BC and its DREs, which revealed the nonlinear change between BC mass concentration and its DREs and emphasizes the importance of regionally transported BC for potential climatic effects.

We investigated aerosol optical properties and the direct radiative effect (DRE) at an urban site in China before and during the COVID-19 lockdown. The total light extinction coefficient (bext) decreased under emission control measures; however, bext from biomass burning increased due to the undiminished need for residential cooking and heating. Biomass burning, rather than traffic-related emissions, became the largest positive effect contributor to aerosol DRE in the lockdown.

Short summary
Looking at characteristics and δ13C compositions of dicarboxylic acids and related compounds in BB aerosols, we used a combined combustion and aging system to generate fresh and aged aerosols from burning straw. The results showed the emission factors (EFaged) of total diacids of aging experiments were around an order of magnitude higher than EFfresh. This meant that dicarboxylic acids are involved with secondary photochemical processes in the atmosphere rather than primary emissions from BB.
