Abstract Aerosol hygroscopic behavior plays a central role in determining climate effects and environmental influence of atmospheric particulates. Water-soluble organic acids (WSOAs) constitute significant fraction aerosols. These have complex impact on aerosol hygroscopicity due to their physical chemical interactions with inorganic salts. The mixing WSOAs salts exerts multiple the growth phase behaviors particles, largely depending composition ratio, acid properties, particle size between...
Abstract. Air pollution in cities seriously impacts public health and regional climate. Turbulent mixing plays a crucial role pollutant formation dissipation, yet current atmospheric models struggle to accurately represent it. The intensity of turbulent varies with model resolution, which has rarely been analyzed. To investigate variations at multi-resolutions their implications for urban transport, we conducted numerical experiments using WRF-Chem 25 km, 5 1 km resolutions. simulated...
Abstract Size‐resolved organic functional group (OFG) concentrations in aerosol particles were measured during January−February 2019 Hefei, a major urban city eastern China. Alkane, carboxylic acid, and hydroxyl groups the main components of (OA), contributing 35.0%, 22.5%, 21.8%, respectively. The mass size distributions OFGs strongly depended on ambient relative humidity (RH). Specifically, OFG 50% higher high‐RH periods than low‐RH periods. peak distribution was 0.56–1 μm periods, while...
Abstract Religious burning (RB) has been identified as a major source of atmospheric aerosols on the Qinghai‐Tibet Plateau. However, there is limited understanding detailed chemical composition, size distribution, and optical properties RB in this region. To characterize these important aerosol properties, ambient PM 2.5 resolved from emissions Lhasa were collected during summer 2019. Organic functional group (OFG) inorganic ion composition was measured using Fourier transform infrared...
