“…Anthropogenic mineral dust can also influence air quality and human health through the processes of their emission, transport, removal, and deposition (Aleksandropoulou et al, 2011;Chen et al, 2013;Huang et al, 2014Huang et al, , 2015aKim et al, 2009;Li et al, 2009;Mahowald and Luo, 2003;Zhang et al, 2005Zhang et al, , 2015. Ginoux et al (2010) estimated that anthropogenic dust accounts for 25 % of all dust aerosols using observational data from satellite products combined with a land-use fraction dataset.…”

Abstract. Mineral dust aerosols (MDs) not only influence the climate by scattering and absorbing solar radiation but also modify cloud properties and change the ecosystem. From 3 April to 16 May 2014, a ground-based mobile laboratory was deployed to measure the optical and microphysical properties of MDs near dust source regions in Wuwei, Zhangye, and Dunhuang (in chronological order) along the Hexi Corridor over northwestern China. Throughout this dust campaign, the hourly averaged (±standard deviation) aerosol scattering coefficients (σ sp , 550 nm) of the particulates with aerodynamic diameters less than 2.5 µm (PM 2.5 ) at these three sites were sequentially 101.5 ± 36.8, 182.2 ± 433.1, and 54.0 ± 32.0 Mm −1 . Correspondingly, the absorption coefficients (σ ap , 637 nm) were 9.7 ± 6.1, 6.0 ± 4.6, and 2.3 ± 0.9 Mm −1 ; single-scattering albedos (ω, 637 nm) were 0.902 ± 0.025, 0.931 ± 0.037, and 0.949 ± 0.020; and scattering Ångström exponents (Å sp , 450-700 nm) of PM 2.5 were 1.28 ± 0.27, 0.77 ± 0.51, and 0.52 ± 0.31. During a severe dust storm in Zhangye (i.e., from 23 to 25 April), the highest values of σ 2.5 sp (∼ 5074 Mm −1 ), backscattering coefficient (σ 2.5 bsp , ∼ 522 Mm −1 ), and ω 637 (∼ 0.993) and the lowest values of backscattering fraction (b 2.5 , ∼ 0.101) at 550 nm and Å 2.5 sp (∼ −0.046) at 450-700 nm, with peak values of aerosol number size distribution (appearing at the particle diameter range of 1-3 µm), exhibited that the atmospheric aerosols were dominated by coarse-mode dust aerosols. It is hypothesized that the relatively higher values of mass scattering efficiency during floating dust episodes in Wuwei and Zhangye are attributed to the anthropogenic soil dust produced by agricultural cultivations.

“…Publication year (Zhang et al 2015d;Gao et al 2017). Owing to high levels of atmospheric pollutant emissions, more serious haze episodes occurs in China after 2013, especially in urban agglomerations such as the Beijing-Tianjin-Hebei region, the Yangtze River Delta area, and the Pearl River Delta area (Fu and Chen 2017;Li et al 2017).…”
