Irrigation and urban greening can mitigate extreme temperatures and reduce adverse health impacts from heat. However, some recent studies suggest these interventions could actually exacerbate heat stress by increasing humidity. These studie...
Impact of shipping emissions regulation on urban aerosol composition changes revealed by receptor and numerical modelling [0.03%]
基于受体和数值模拟的船舶排放控制对城市气溶胶的影响研究

Anthropogenic aerosols mask the climate warming caused by greenhouse gases (GHGs). In the absence of observational constraints, large uncertainties plague the estimates of this masking effect. Here we used the abrupt reduction in anthropoge...
Importance of humidity for characterization and communication of dangerous heatwave conditions [0.03%]
湿度对表征和传播危险热浪条件的重要性

Heatwaves are one of the leading causes of climate-induced mortality. Using the examples of recent heatwaves in Europe, the United States and Asia, we illustrate how the communication of dangerous conditions based on temperature maps alone ...
The contribution of industrial emissions to ozone pollution: identified using ozone formation path tracing approach [0.03%]
基于臭氧生成过程的源解析方法及其在工业排放对京津冀地区臭氧污染贡献中的应用研究
Junlei Zhan,Wei Ma,Boying Song et al.
Junlei Zhan et al.
Wintertime meteorological conditions are usually unfavorable for ozone (O3) formation due to weak solar irradiation and low temperature. Here, we observed a prominent wintertime O3 pollution event in Shijiazhuang (SJZ) during the Chinese Ne...

The use of air quality monitoring networks to inform urban policies is critical especially where urban populations are exposed to unprecedented levels of air pollution. High costs, however, limit city governments' ability to deploy referenc...
Non-linearity of secondary pollutant formation estimated from emissions data and measured precursor-secondary pollutant relationships [0.03%]
基于排放清单数据和观测的前体物-二次污染物关系估算二次污染非线性因子
Roy M Harrison,David C S Beddows,Chengxu Tong et al.
Roy M Harrison et al.
In order to predict the impacts of reductions in air pollutant emissions, it is important to know whether secondary pollutant concentrations will decline in direct proportion to the reduction in their precursor, referred to as linearity. Tr...
