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.

Biogenic secondary organic aerosol (BSOA), as an important atmospheric component, is prevalent within the boundary layer and can influence air quality and human health. Our observations demonstrate that anthropogenic NOx and the enhanced aerosol water driven by sulfate inhibit BSOA formation in lifting air masses, leading to a moderate reduction in the SOA burden in the upper boundary layer.

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.

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.

This study examines aerosol hygroscopicity and mixing states at Mt. Hua (2060 m), a key free-tropospheric site in central China. We found size-dependent hygroscopicity, source-related variations, and humidity-driven processing, distinguishing this region from other high-altitude sites, which may provide key constraints for aerosol-cloud and regional climate models.

The influence of anthropogenic pollution on atmospheric organic composition was studied to explore the chemical processes of anthropogenic–biogenic interactions in the Qinling Mountains region of central China using advanced Orbitrap mass spectrometry. Organic molecular species exhibited distinct seasonal variabilities and were more abundant and chemically diverse in winter. Anthropogenic pollution played key roles in altering their composition and related properties under various conditions.

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.

Brown carbon (BrC) is prevalent in the troposphere and can efficiently absorb solar and terrestrial radiation. Our observations show that the enhanced light absorption of BrC relative to black carbon at the tropopause can be attributed to the formation of nitrogen-containing organic compounds through the aqueous-phase reactions of carbonyls with ammonium.

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.

We conducted black carbon (BC) source apportionment on the southeastern Tibetan Plateau (TP) by an improved aethalometer model with the site-dependent Ångström exponent and BC mass absorption cross section (MAC). The result shows that the biomass-burning BC on the TP is slightly higher than fossil fuel BC, mainly from cross-border transportation instead of the local region, and the BC radiative effect is lower than that in the southwestern Himalaya but higher than that on the northeastern TP.

Light-absorbing carbonaceous (LAC) aerosol is an important influencing factor for global climate forcing. In this study, we used a receptor model coupling multi-wavelength absorption with chemical species to explore the source-specific LAC optical properties at a tropical marine monsoon climate zone. The results can improve our understanding of the LAC radiative effects caused by ship emissions.

Recently, China has promulgated a series of regulations to reduce air pollutants. The decreased black carbon (BC) and co-emitted pollutants could affect the interactions between BC and other aerosols, which in turn results in changes in BC. Herein, we re-assessed the characteristics of BC of a representative pollution site in northern China in the final year of the Chinese
Action Plan for the Prevention and Control of Air Pollution.

Short summary
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.
