Abstract. Oil and natural gas are important for energy supply around the world. The exploring, drilling, transportation processing in oil regions can release a lot of volatile organic compounds (VOCs). To understand VOC levels, compositions sources such regions, an station northwest China was chosen as research site 57 VOCs designated photochemical precursors were continuously measured entire year (September 2014–August 2015) using online monitoring system. average concentration total 297 ±...
Biomass burning (BB) has significant impacts on air quality, climate and human health. In China, the BB emission changed substantially over past decades while multi-year variation held high uncertainty driving forces have addressed little attention. Here, this research aimed to conduct a comprehensive systematic analysis of in China provided precise targeted reduction suggestions. The moving for from 2003 2014 was clearly identified, by view reliable estimation anthropogenic impacts....
Abstract. Open biomass burning (OBB) has significant impacts on air pollution, climate change and potential human health. OBB gathered wide attention but with little focus the annual variation of pollutant emission. Central eastern China (CEC) is one most polluted regions in China. This study aims to provide a state-of-the-art estimation emissions from CEC 2003 2015, by adopting satellite observation dataset – burned area product (MCD64Al) active fire (MCD14 ML) along local data (updated...
Levoglucosan (LG) emitted from non-biomass burning (non-BB) sources has given rise to biased or even unreasonable source identification results when adopting LG as a distinct marker of biomass (BB). The estimation emission and its spatiotemporal variation for various are the keys reducing uncertainty. This study first developed inventory China 25 sub-type belonging eight categories, with 3 km × spatial resolution monthly distribution. total in 2014 was 145.7 Gg. Domestic BB open contributed...
Emissions of light-absorbing black carbon (BC) and organic aerosol (OA) from biomass burning are presented as complex mixtures, which introduce challenges in modeling their absorbing properties. In this study, we chose typical residential wood emission used a novel designed chamber to investigate the early stage evolution plumes different phases under real ambient conditions. The detailed mixing state between BC OA was evaluated, on basis optical performed achieve closure aerosol-absorbing...
Abstract. Black carbon (BC), which is formed from the incomplete combustion of fuel sources (mainly fossil fuel, biofuel and open biomass burning), a chemically inert optical absorber in atmosphere. It has significant impacts on global climate, regional air quality human health. During transportation, its physical chemical characteristics as well change dramatically. To investigate properties BC (i.e., mass concentration, properties) during intra-regional transport between southern edge...
Abstract The less improvement of ambient visibility suspects the government’s efforts on alleviating PM 2.5 pollution. COVID-19 lockdown reduced and increased in Wuhan. Compared to pre-lockdown period, concentration decreased by 39.0 μg m −3 , dominated NH 4 NO 3 mass reduction (24.8 ) during period. threshold corresponding 10 km (PTV varied 54–175 an hourly 54 was recommended prevent haze occurrence. measures elevated PTV 9–58 as decreases scattering efficiency optical hygroscopicity. 107%,...
Light-absorbing organic carbon (OC), sometimes known as Brown Carbon (BrC), has been recognized an important fraction of carbonaceous aerosols substantially affecting radiative forcing. This study firstly developed a bottom-up estimate global primary BrC, and discussed its spatiotemporal distribution source contributions from 1960 to 2010. The total BrC emission both natural anthropogenic sources in 2010 was 7.26 (5.98–8.93 interquartile range) Tg, with 43.5% sources. High emissions were...
