PM2.5 data from major cities in the southern North China Plain during 2013–2015 were comprehensively analyzed relative to variation features, meteorology effects, and regional transport contributions. The annual average ranged from 87 to 123 μg m... see more

 

Hui Shi, Qingqing He and Wenting Zhang

A substantial number of studies have analyzed how driving factors impact aerosols, but they have been little concerned with the spatial heterogeneity of aerosols and the factors that impact aerosols. The spatial distributions of the aerosol optical depth ... see more

 

Chao Wang and Lijuan Wang

Using ERA-Interim daily reanalysis and precipitation data, the combined effects of East Asia-Pacific (EAP) and Silk Road (SR) teleconnection patterns on summer precipitation in Southern China were investigated on synoptic to sub-monthly timescales. Combin... see more

 

Wenjie Zhao, Yiran Peng, Bin Wang and Jiangnan Li

The cloud longwave (LW) scattering effect has been ignored in most current climate models. To investigate its climate impact, we apply an eight-stream DIScrete Ordinates Radiative Transfer (DISORT) scheme to include the cloud LW scattering in the General ... see more

 

Georgios Papailias and Ilias Mavroidis

This paper addresses the atmospheric emissions of CO2, SO2, H2S, NOx, and volatile organic compounds (VOCs) from oil and gas extraction and production in the Gulf of Kavala. This is currently the only location of oil and gas production in Greece. Faciliti... see more

 

Qiqi Yang, Qiang Dai, Dawei Han, Xuehong Zhu and Shuliang Zhang

Designed for rainstorms and flooding, hydrosystems are largely based on local rainfall Intensity–Duration–Frequency (IDF) curves which include nonstationary components accounting for climate variability. IDF curves are commonly calculated using downscalin... see more

 

Hai-Ying Liu, Daniel Dunea, Stefania Iordache and Alin Pohoata

Exposure to airborne fine particulate matter (PM2.5) carries substantial health risks, particularly for younger children (0–10 years). Epidemiological evidence indicates that children are more susceptible to PM health effects than adults. We conduct... see more

 

Mingzhao Yu, Bingfang Wu, Hongwei Zeng, Qiang Xing and Weiwei Zhu

The aerodynamic roughness length (z0m) is a crucial parameter for reliably simulating turbulent exchanges between the land surface and the atmosphere. Due to the large number of input variables related to vegetation growth and aerodynamic conditions near ... see more

 

Noppol Arunrat, Nathsuda Pumijumnong and Sukanya Sereenonchai

Particulate pollution is a continual problem which is usually caused by the burning of crop residues in highland agricultural systems. The objectives of this study are to investigate crop-residue management and estimate the amount of pollutant emissions f... see more

 

Siwatt Pongpiachan, Akihiro Iijima and Junji Cao

Bonfire night is a worldwide phenomenon given to numerous annual celebrations characterised by bonfires and fireworks. Since Thailand has no national ambient air quality standards for metal particulates, it is important to investigate the impacts of parti... see more

 

Sium Gebremariam, Siwei Li and Mengsteab Weldegaber

The correlation between aerosol particulate matter with aerodynamic diameter =2.5 µ m (PM2.5) and cloud base height (CBH) of low clouds (CBH lower than 1.5 km a.g.l.) at Baltimore and New York, United States, for an 8 year period (2007–2014) was i... see more

 

Nan Shan, Zhongjie Shi, Xiaohui Yang, Hao Guo, Xiao Zhang and Zhiyong Zhang

The response of potential evapotranspiration (ET0) to widespread irrigation is important to fully understand future regional climate changes and to infer adaptive management of agricultural water resources. The quantitative impact of irrigation on ET0 fro... see more

 

Chih-Chiang Wei, Po-Chun Peng, Cheng-Han Tsai and Chien-Lin Huang

Taiwan is located on a route where typhoons often strike. Each year, the strong winds accompanying typhoons are a substantial threat and cause significant damage. However, because the terrains of high mountains in Taiwan vary greatly, when a typhoon passe... see more

 

Sean M. McGinn and Thomas K. Flesch

Concentrated animal feeding operations (CAFO) such as open-air beef cattle feedlots are known ‘hot spots’ of emissions of numerous gases including the major greenhouse gases methane, nitrous oxide, and carbon dioxide. Some work has documented CAFOs to der... see more

 

Jing Chai, Fei Liu, Jian Liu and Xinyong Shen

In this study, we investigate global monsoon precipitation (GMP) changes between the Present Warm Period (PWP, 1900–2000) and the Little Ice Age (LIA, 1250–1850) by performing millennium sensitivity simulations using the Community Earth System Model versi... see more

 

Xiangwei Zhao, Qian Gao, Meng Sun, Yunchuan Xue, RuiJin Ma, Xingyuan Xiao and Bo Ai

Air pollution has impacted people’s lives in urban China, and the analysis of the distribution and driving factors behind air quality has become a current research focus. In this study, the temporal heterogeneity of air quality (AQ) and the dominant air p... see more

 

Nicholas Clements, Patricia Keady, Joanne B. Emerson, Noah Fierer and Shelly L. Miller

Aerosol measurements were collected at fifteen homes over the course of one year in Colorado (USA) to understand the temporal variability of indoor air particulate matter and bacterial concentrations and their relationship with home characteristics, inhab... see more

We refined the aqueous-phase sulfate (SO42-) production in the state-of-the-art Community Multiscale Air Quality (CMAQ) model during the Japanese model inter-comparison project, known as Japan’s Study for Reference Air Quality Modeling (J-STREAM). In Japa... see more

 

Zhengyao Lu, Zhengyu Liu, Jiang Zhu and Kim M. Cobb

The Earth has seen El Niño-Southern Oscillation (ENSO)—the leading mode of interannual climate variability—for at least millennia and likely over millions of years. This paper reviews previous studies from perspectives of both paleoclimate proxy data (fro... see more
