TL;DR: In this article, an intensive measurement campaign was conducted at Xi'an, China from Dec. 2012 to Jan. 2013 to investigate the sources and physicochemical characteristics of refractory BC (rBC) and its direct radiative forcing at the surface.

TL;DR: In this article, the light absorption properties and chromophore composition of brown carbon aerosol (BrC) were investigated for samples collected in Xi'an, northwestern China, from 2015 to 2016.

TL;DR: In this paper, an intensive measurement campaign was conducted at Qinghai Lake (~ 3200 m above sea level) at the edge of the northeastern Qinghai-Tibetan Plateau during winter using a ground-based single particle soot photometer (SP2) and a photoacoustic extinctiometer (PAX).

TL;DR: In this paper, the authors measured the emission factors for mass and carbonaceous particles from residential coal combustion and agricultural biomass burning in the laboratory simulations and found that the average PM 2.5, organic carbon (OC) and elemental carbon (EC) EFs from the combustion of a mixture of bituminous and anthracite coals were 6.1−7.1g−kg −1, 1.9−±2.5, OC and EC EFs were 14.4±3.8, respectively, while the average OC/EC ratio for agricultural

TL;DR: In this paper, an Aerodyne quadrupole aerosol chemical speciation monitor (Q-ACSM), combined with other online instruments, was used to characterize the sub-micrometer particulate matter (diameter ǫ 1 µ m, PM1 ) in Beijing during summer and winter 2015.
