Abstract Aerosol‐planetary boundary layer (PBL) interactions have been found to enhance air pollution in megacities China. We show that black carbon (BC) aerosols play the key role modifying PBL meteorology and hence enhancing haze pollution. With model simulations data analysis from various field observations December 2013, we demonstrate BC induces heating PBL, particularly upper resulting decreased surface heat flux substantially depresses development of consequently enhances occurrences...
To control the spread of 2019 novel coronavirus (COVID-19), China imposed nationwide restrictions on movement its population (lockdown) after Chinese New Year 2020, leading to large reductions in economic activities and associated emissions. Despite such decreases primary pollution, there were nonetheless several periods heavy haze pollution eastern China, raising questions about well-established relationship between human air quality. Here, using comprehensive measurements modeling, we show...
The existence of gas‐phase ammonia (NH 3 ) in the atmosphere and its interaction with other trace chemical species could have a substantial impact on tropospheric chemistry global climate change. China is large agricultural country an enormous animal population, tremendous nitrogen fertilizer consumption and, consequently, emission NH . Despite importance (N) cycle, considerable inaccuracies uncertainty exist regarding China. In this study, comprehensive inventory was compiled for 1 km ×...
China has been experiencing fine particle (i.e., aerodynamic diameters ≤ 2.5 µm; PM2.5) pollution and acid rain in recent decades, which exert adverse impacts on human health the ecosystem. Recently, ammonia NH3) emission reduction proposed as a strategic option to mitigate haze pollution. However, atmospheric NH3 is also closely bound nitrogen deposition rain, comprehensive of control are still poorly understood China. In this study, by integrating chemical transport model with...
GRASP (Generalized Retrieval of Aerosol and Surface Properties) is the first unified algorithm to be developed for characterizing atmospheric properties gathered from a variety remote sensing observations (an introductory video available elsewhere1). based on recent algorithm2 created improve aerosol retrieval French Space Agency’s PARASOL3 imager over bright surfaces like deserts where high surface reflectance dwarfs signal aerosols. Moreover, relies heritage advances4–7 implemented...
Abstract. Ammonia (NH3) can interact in the atmosphere with other trace chemical species, which lead to detrimental environmental consequences, such as formation of fine particulates and ultimately global climate change. China is a major agricultural country, livestock numbers nitrogen fertilizer use have increased drastically since 1978, following rapid economic industrial development experienced by country. In this study, comprehensive NH3 emissions inventories were compiled for 1980–2012....
Abstract Atmospheric aerosols have been found to influence the development of planetary boundary layer (PBL) and hence enhance haze pollution in megacities. Previous works on aerosol‐PBL interaction were mainly based model simulation for short‐term cases; so far, there is a lack long‐term observational evidences. In this study, multiyear measurements reanalysis meteorological data, we give evidences its impact aggravation. We significant heating upper PBL with maximum temperature change...
Abstract. Haze pollution caused by PM2.5 is the largest air quality concern in China recent years. Long-term measurements of and precursors chemical speciation are crucially important for evaluating efficiency emission control, understanding formation transport associated with change meteorology, accessing impact human activities on regional climate change. Here we reported long-term continuous PM2.5, components, their at a background station, Station Observing Regional Processes Earth...
Recent evidence shows that carbon emissions in China are likely to peak ahead of 2030. However, the social and economic impacts such an early have rarely been assessed. Here we focus on costs health benefits different mitigation pathways, considering both possible socio-economic futures varying ambitions climate policies. We find before 2030 line with 1.5 °C target could avoid ~118,000 ~614,000 PM

Abstract Investigating sulfate formation processes is important not only for air pollution control but also understanding the climate system. Although mechanisms of secondary production have been widely studied, in situ observational evidence implicating an role NO 2 SO oxidation real atmosphere has rare. In this study, we report two unique cases, from intensive campaign conducted at Station Observing Regional Processes Earth System (SORPES) East China, showing distinctly different by and...
Abstract. Black carbon (BC) has been identified to play a critical role in aerosol–planetary boundary layer (PBL) interaction and further deterioration of near-surface air pollution megacities, which referred as the “dome effect”. However, impacts key factors that influence this effect, such vertical distribution aging processes BC, well underlying land surface, have not quantitatively explored yet. Here, based on available situ measurements meteorology atmospheric aerosols together with...
Abstract. Ground-based multi-axis differential optical absorption spectroscopy (MAX-DOAS) and lidar measurements were performed in Shanghai, China, during May 2016 to investigate the vertical distribution of summertime atmospheric pollutants. In this study, profiles aerosol extinction coefficient, nitrogen dioxide (NO2) formaldehyde (HCHO) concentrations retrieved from MAX-DOAS using Heidelberg Profile (HEIPRO) algorithm, while ozone (O3) was obtained an lidar. Sensitivity study profile...
Abstract. The North China Plain has been identified as a significant hotspot of ammonia (NH3) due to extensive agricultural activities. Satellite observations suggest increase about 30 % in tropospheric gas-phase NH3 concentrations this area during 2008–2016. However, the estimated emissions decreased slightly by 7 because changes Chinese practices, i.e., transition fertilizer types from ammonium carbonate urea, and livestock rearing system free-range intensive farming. We note that sulfur...
Abstract. Long-range-transported Canadian smoke layers in the stratosphere over northern France were detected by three lidar systems August 2017. The peaked optical depth of stratospheric layer exceeds 0.20 at 532 nm, which is comparable with simultaneous tropospheric aerosol depth. measurements satellite sensors revealed that observed plumes transported from wildfires after being lofted strong pyro-cumulonimbus. Case studies two observation sites, Lille (lat 50.612, long 3.142, 60 m a.s.l.)...
Extreme wildfires threaten human lives, air quality, and ecosystems. Meteorology plays a vital role in wildfire behaviors, the links between climate have been widely studied. However, it is not fully clear how fire-weather feedback affects short-term variability, which undermines our ability to mitigate fire disasters. Here, we show primacy of synoptic-scale driving extreme fires Mediterranean monsoon regimes West Coast United States Southeastern Asia. We found that radiative effects smoke...
Despite the large reduction in anthropogenic activities due to outbreak of COVID-19, air quality China has witnessed little improvement and featured great regional disparities. Here, by combining observational data simulations, this work aims understand diverse response two city clusters, Yangtze River Delta region (YRD) Pearl (PRD), China. Though there was a noticeable drop primary pollutants both regions, differently, maximum daily 8 h average ozone (O3) soared 20.6-76.8% YRD but decreased...
Enhanced anthropogenic and biogenic interaction by approaching typhoons deteriorates cross-regional ozone pollution in China.
Abstract China pledged to achieve carbon neutrality by 2060 combat global climate change, yet the resulting multi-aspect domestic impacts are not fully analysed due an incomplete understanding of underlying anthropogenic–natural interactions. Building integrated cross-disciplinary modelling framework that can capture feedbacks changing aerosols on meteorology, here we highlight amplified air quality, human health and renewable energy self-reinforcing synergies China’s neutral target in...
