Direct identification of total and missing OH reactivities from light-duty gasoline vehicle exhaust in China based on LP-LIF measurement.
Xuehui Liu,Zibing Yuan,Qinge Sha,Shengrong Lou,Hong Wang,Xin Li,Junyu Zheng,Bin Yuan,Min Shao +8 more
TL;DR: In this paper , the authors improved the laser photolysis-laser-induced fluorescence (LP-LIF) technique and applied it to directly measure the total OH reactivity (TOR) in exhaust gas from light-duty gasoline vehicles in China.
Journal ArticleDOI
Minimum taxi fleet algorithm considering human spatiotemporal behaviors.
TL;DR: In this paper , the authors proposed a travel scheduling solution that comprehensively considers time and space costs, namely, the Spatial-Temporal Hopcroft-Karp (STHK) algorithm, which not only considers the minimum fleet size required to meet the urban travel needs but also considers the travel time and distance of the fleet.

Effect of sampling duration on the estimate of pollutant concentration behind a heavy-duty vehicle: A large-eddy simulation.
TL;DR: In this paper , the authors examined how sampling duration affects the uncertainty of the measured concentrations in plume chasing and revealed the mechanism leading to the variance in concentration measurements which is attributed to sampling duration.

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.
