Aerosol effects on climate, weather, and air quality depend on characteristics of individual particles, which are tremendously diverse and change in time. Particle-resolved models are the only models able to capture this diversity in partic...
Effect of Long-Range Transported Aerosol on Urban Air Quality in Eastern Germany [0.03%]
长距离输送气溶胶对德国东部城市空气质量的影响

Samira Atabakhsh et al.
Submicron particles (PM1) play a crucial role in air quality and human health. This study investigates the influence of long-range transport (LRT) on urban aerosol levels in Leipzig, Germany, using high-resolution aerosol mass spectrometry ...
Aerosol Hygroscopicity and Surface-Active Coverage for the Droplet Growth of Aerosol Mixtures [0.03%]
混合气溶胶的吸湿性和表面活性覆盖对气溶胶液滴增长的影响

Nahin Ferdousi-Rokib et al.
The partitioning between inorganic salts and organic compounds within individual particles is a key factor that influences the uptake of water by particles. In this study, we investigated the aerosol hygroscopicity of ammonium sulfate (AS) ...
Interpreting Measurements of the Global Diurnal Variation of Fine Particulate Matter Using the GEOS-Chem Model [0.03%]
基于GEOS-chem模型的全球细颗粒物日变化观测解释
Yanshun Li,Randall V Martin,Yuanjian Zhang et al.
Yanshun Li et al.
Globally distributed measurements of the diurnal variation of fine particulate matter (PM2.5) reveal a remarkable overall consistency with similar bimodal patterns and some regional variation, neither of which is well understood. We interpr...
Influence of Relative Humidity and Seed Particles on Molecular Composition of α‑Pinene Secondary Organic Aerosol [0.03%]
相对湿度和凝结核对α-蒎烯二次有机气溶胶分子组成的影响
Jens Top,Natasha M Garner,Félix Sari Doré et al.
Jens Top et al.
Secondary organic aerosol (SOA), a major component of submicrometer particles, is critical to the climate and human health. SOA can form through nucleation of low-volatility organic compounds, following atmospheric oxidation, or by condensi...
Quantifying Dissemination of Antibiotic Resistance Genes in Air from a Dairy Farm and Swine Farm [0.03%]
定量分析来自奶牛场和养猪场空气中的抗生素抗性基因的传播量
David A Kormos,Gabriel Isaacman-VanWertz,Jactone A Ogejo et al.
David A Kormos et al.
Farms are a suspected source of dissemination of antibiotic resistance genes (ARGs) to the atmosphere, but their contribution remains poorly quantified. This study investigated the concentrations, emission rates, and particle size distribut...
Year-Round Analysis of Multiphase Sulfate Production in Aerosol Particles in East Asia [0.03%]
东亚太气溶胶粒子硫酸盐多阶段生成全年特征分析研究
Katherine R Travis,Benjamin A Nault,James H Crawford et al.
Katherine R Travis et al.
Missing sulfate production pathways have been implicated as the cause of model underestimates of sulfate during haze events in East Asia. We add multiphase oxidation of SO2 in aerosol particles by H2O2, O3, NO2, HCHO, and O2, catalyzed by t...
Characterizing Air Quality Impacts Related to North Atlantic Offshore Emissions Sources [0.03%]

Wind energy projects are being planned and constructed off the northern Atlantic coast to provide additional energy capacity to the eastern U.S. Emissions related to construction, operation, and routine maintenance of these offshore wind pr...
Assessing the Impact of Wildfire Smoke Transport Through Chemical Transport Modeling, Satellite Retrievals, and Ground-Based Observations of Ozone in Rural Nevada [0.03%]
基于化学输送模式、卫星遥感及地面观测评估野火烟雾输送对内华达州农村地区臭氧的影响
Yi Ji,Xiaodan Zhang,Abiola S Lawal et al.
Yi Ji et al.
Wildfires emit a large amount of ozone precursors, nitrogen oxides, and particulate matter into the troposphere and sometimes the stratosphere. With the increasing wildfire events in recent years, the western U.S. regions may experience cha...
Emissions of Volatile Organic Compounds from Brake Wear and Their Role in Ultrafine Particle Nucleation [0.03%]
制动磨损产生的挥发性有机化合物及其在超细颗粒核化中的作用
Olivier Durif,Lucas Bard,Karine Elihn et al.
Olivier Durif et al.
The emission of volatile organic compounds (VOCs) from brake wear is a relatively underexplored aspect of nonexhaust traffic emissions. We employed a proton-transfer-reaction time-of-flight mass spectrometer to investigate the real-time emi...
