Improving PM2.5 Air Quality Model Forecasts in China Using a Bias-Correction Framework
TL;DR: A bias-correction framework that utilized the historic relationship between the model biases and forecasted and observational variables to post-process the current forecasts to improve the PM2.5 air quality model forecasts in China is proposed.

Da Pan,Lei Tao,Kang Sun,Levi M. Golston,David J. Miller,David J. Miller,Tong Zhu,Yue Qin,Yan Zhang,Denise L. Mauzerall,Mark A. Zondlo +10 more
TL;DR: It is found that switching to NGVs from conventional vehicles in China has led to a net increase in greenhouse gas (GHG) emissions since 2000 and the next decade will be critical for China to reverse the trend with the upcoming China VI standard for heavy-duty vehicles.
Journal ArticleDOI
Recent advances in three-way catalysts of natural gas vehicles
TL;DR: In this article, a review of the recent research advances in TWC for NGVs, including the technical fundamentals, classic components (active phases, supports, and promoters), novel preparations of catalysts, resistance to thermal and chemical aging, current challenges and future perspectives are discussed.

Variation tendency of pollution characterization, sources, and health risks of PM2.5-bound polycyclic aromatic hydrocarbons in an emerging megacity in China: Based on three-year data
TL;DR: In this paper, a total of 180 PM 2.5 samples were collected from December 3, 2013 to October 20, 2016 in an urban area in Zhengzhou, China, and 16 polycyclic aromatic hydrocarbons (PAHs) were analyzed.

TL;DR: In this paper, the authors provided an assessment of black-carbon climate forcing that is comprehensive in its inclusion of all known and relevant processes and that is quantitative in providing best estimates and uncertainties of the main forcing terms: direct solar absorption; influence on liquid, mixed phase, and ice clouds; and deposition on snow and ice.

TL;DR: The results suggest that, in addition to mitigating primary particulate emissions, reducing the emissions of secondary aerosol precursors from fossil fuel combustion and biomass burning is likely to be important for controlling China’s PM2.5 levels and for reducing the environmental, economic and health impacts resulting from particulate pollution.

Strong radiative heating due to the mixing state of black carbon in atmospheric aerosols
TL;DR: Simulation of the evolution of the chemical composition of aerosols finds that the mixing state and direct forcing of the black-carbon component approach those of an internal mixture, largely due to coagulation and growth of aerosol particles.

Characteristics of PM 2.5 speciation in representative megacities and across China
TL;DR: Based on PM2.5 chemical data sets from literature and from surface observations, chemical species and reconstructed speciation of PM2.5 in representative Chinese megacities and across China were compared to draw insights into the characteristics of PM 2.5 speciation as mentioned in this paper.
