Tom V Kokkonen,Yuning Xie,Pauli Paasonen et al.
Tom V Kokkonen et al.
The effects of the urban morphological characteristics on the spatial variation of near-surface PM2.5 air quality were examined. Unlike previous studies, we performed the analyses in real urban environments using continuous observations cov...
A modelling study of OH, NO3 and H2SO4 in 2007-2018 at SMEAR II, Finland: analysis of long-term trends [0.03%]
2007-2018年芬兰SMEAR II地区OH、NO3和H2SO4的模型研究：长期趋势分析
Dean Chen,Carlton Xavier,Petri Clusius et al.
Dean Chen et al.
Major atmospheric oxidants (OH, O3 and NO3) dominate the atmospheric oxidation capacity, while H2SO4 is considered as a main driver for new particle formation. Although numerous studies have investigated the long-term trend of ozone in Euro...
Molecular characterization of ultrafine particles using extractive electrospray time-of-flight mass spectrometry [0.03%]
使用提取电喷雾飞行时间质谱法对超细颗粒进行分子特征分析
Mihnea Surdu,Veronika Pospisilova,Mao Xiao et al.
Mihnea Surdu et al.
Aerosol particles negatively affect human health while also having climatic relevance due to, for example, their ability to act as cloud condensation nuclei. Ultrafine particles (diameter D p < 100 nm) typically comprise the largest fractio...

Giancarlo Ciarelli et al.
The spread of COVID-19 has posed serious challenges for the global communities. To reduce the circulation of the infection, governmental bodies have imposed different lockdown measures at various levels of complexity and duration. As a resu...
Emerging Investigator Series: COVID-19 lockdown effects on aerosol particle size distributions in northern Italy [0.03%]
新兴 investigator 系列：COVID-19 锁国令对意大利北部气溶胶颗粒粒径分布的影响
Jiali Shen,Alessandro Bigi,Angela Marinoni et al.
Jiali Shen et al.
The lockdown measures implemented to curb the COVID-19 epidemic in Italy reduced human mobility dramatically, which resulted in a marked decline in traffic intensity. In this study, we present the effect of lockdown measures on several air ...
Mineral and biological ice-nucleating particles above the South East of the British Isles [0.03%]
英国东南部的矿物和生物冰核粒子
A Sanchez-Marroquin,J S West,I T Burke et al.
A Sanchez-Marroquin et al.
A small fraction of aerosol particles known as Ice-Nucleating Particles (INPs) have the potential to trigger ice formation in cloud droplets at higher temperatures than homogeneous freezing. INPs can strongly reduce the water content and al...
