Relationships between Near-Surface Horizontal Dust Fluxes and Dust Depositions at the Centre and Edge of the Taklamakan Desert

The emission, transport, and deposition of dust are frequently the focus aerosol studies. However, owing to limited observation data, few studies have examined relationships between key parameters especially in typical source areas. Therefore, investigating relationship near-surface horizontal fluxes depositions desert areas can further help us understand movement transport patterns aerosols. Based on observational experiments two parameters, this study focused quantitative flux (Q) (D). A 13-month long sample collection experiment was conducted from August 2017 2018 at Xiaotang Station (hereafter XT,40°48′ N, 84°18′ E) Tazhong TZ, 39°00′ 83°40′ E). results show that observed D Q peaks coincided with periods high storm incidence, greatest accumulation spring. Moreover, both decreased increasing height XT, phenomenon remained a monthly scale. In contrast, no clear decreasing pattern TZ. Additionally, relatively coarse particles, primarily local sources, dominated locations. proportion deposited particles size <20 μm slightly higher XT than Specifically, contained finer more long-distance transport. Furthermore, had significantly positive linear correlation XT; however, significant Analysis wind dynamics surface particle indicated topographic differences stations caused these correlation.
