Black carbon, primary brown carbon and secondary brown carbon are the leading light-absorbing carbonaceous aerosols (LACs) that contribute significantly to climate change. We modified the GEOS-Chem model to simulate the climate change by LACs based on a local emission inventory and explored the impacts of LAC properties and atmospheric variables on the corresponding direct radiative forcings (DRFs) in seven regions of China. The study confirms the warming effect of LACs and deepens our knowledge of their climatic effects.

NPF (new particle formation) is a key global CCN (cloud condensation nuclei) source, but its contribution at the polluted boundary-layer top remains unclear. Based on mountaintop observations in the Yangtze River Delta, we show that under polluted conditions, NPF at the boundary-layer top is enhanced and accelerates its conversion to CCN. Ammonia plays a key role, and a newly defined "Time Window" metric highlights the importance of oxidation-driven growth and regional transport in this process.

The methane leakage from natural gas may offset the reduced CO2 emissions from its combustion, To quantify its effect, we established the flux observation platform in Beijing, the results showed that natural gas has become a common source of both after the transformation of energy structure, the natural gas could escape during production, storage and use. Although the natural gas leakage rate is not high (1.12 %), the greenhouse effect caused by natural gas leakage can not be ignored.

This research presents China's first long-term (1981–2023) hyperspectral ultraviolet radiation dataset with exceptional 0.5 nm spectral resolution. The spectral detail enables precise identification of UV absorption characteristics and atmospheric interactions previously obscured in conventional broadband measurements. These results provide new capabilities for monitoring ozone depletion, and optimizing solar energy systems across China's diverse climatic regions.

Aerosol vertical distribution that plays a crucial role in aerosol–photolysis interaction (API) remains underrepresented in chemical models. We integrated lidar and radiosonde observations to constrain the simulated aerosol profiles over North China and quantified the photochemical responses. The increased photolysis rates in the lower layers led to increased ozone and accounted for a 36 %–56 % reduction in API effects, resulting in enhanced atmospheric oxidizing capacity and aerosol formation.

Online vertical gradient measurements of volatile organic compounds (VOCs), ozone, and NOx were conducted based on a 325 m tall tower in urban Beijing. Vertical changes in the concentrations, compositions, key drivers, and environmental impacts of VOCs were analyzed in this study. We find that VOC species display differentiated vertical variation patterns and distinct roles in contributing to photochemical ozone formation with increasing height in the urban planetary boundary layer.

By integrating the SNICAR model with Polar-WRF, we find that 50 ng g−1 black carbon (BC) deposition decreases snow albedo, increasing radiative forcing (RF) by 1–4 W m−2, especially in Greenland, Baffin Island, and eastern Siberia. The impact is strongly linked to BC mass, with deep snowpacks showing greater sensitivity. Snowmelt and land–atmosphere interactions are crucial. High-resolution modelling is necessary to better understand these effects on Arctic climate change.

Limited ultraviolet (UV) measurements hindered further investigation of its health effects. This study used a machine learning algorithm to predict UV radiation with a daily and 10 km resolution of high accuracy in mainland China in 2005–2020. Then, uneven spatial distribution and population exposure risks as well as increased temporal trend of UV radiation were found in China. The long-term and high-quality UV dataset could further facilitate health-related research in the future.

We provide the average vertical profiles of black carbon (BC) concentration, size distribution and coating thickness at different times of the day in an urban area based on 112 vertical profiles. In addition, it is found that BC in the residual layer generally has a thicker coating, higher absorption enhancement and hygroscopicity than on the surface. Such aged BC could enter into the boundary layer and influence the BC properties in the early morning.

We comprehensively investigated the mass growth potential, oxidation degree, formation pathway, and mass spectra features of typical urban-lifestyle secondary organic aerosols (SOAs) including vehicle SOAs and cooking SOAs. The mass spectra we acquired could provide necessary references to estimate the mass fractions of vehicle and cooking SOAs in the atmosphere, which would greatly decrease the uncertainty in air quality evaluation and health risk assessment in urban areas.

Through simultaneous online measurements of detailed aerosol compositions at both surface and surface-influenced mountain sites, the evolution of aerosol composition during daytime vertical transport was investigated. The results show that, from surface to the top of the planetary boundary layer, the oxidation state of organic aerosol had been significantly enhanced due to evaporation and further oxidation of these evaporated gases.

Different weather types will shape significantly different structures of the pollution boundary layer. The findings of this study allow us to understand the inherent difference among heavy pollution boundary layers; in addition, they reveal the formation mechanism of haze pollution from an integrated synoptic-scale and boundary layer structure perspective.

Weak atmospheric dilution capability is a key factor leading to the frequent occurrence of serious air pollution. This study aims to analyze the mixing layer dilution capability of the atmosphere and to quantify the mixing layer PM2.5 transport flux. Our results showed the main controlling factors during the transition and heavy polluted period in Beijing. The results help in understanding the causes of air pollution and making decisions on prevention and control of air pollution.
