“…This phenomenon becomes more acute with lower moisture content of saline sand. Although this problem was previously reported in the research literature, no good solution has been found (Chepil, 1956;Nickling, 1978;Nickling and Ecclestone, 1981;Argaman et al, 2006;Nield et al, 2016). Even though we measured the moisture content of 1-mm depth of saline sand on the surface, which was approximately the total thickness of 5 layers of sand particles (200.00 μm for each layer), the error was still inevitable because surface moisture of wet sand is the key factor in controlling the initiation of particle motion.…”

“…Surfaces that are wet, rough, aggregated, crusted and partially covered with crop residue generally have a higher threshold shear velocity than surfaces that are dry, smooth, single-grained, non-crusted and devoid of vegetation (Ravi et al, 2006;Davidson-Arnott et al, 2008;Ishizuka et al, 2008;Sharratt and Vaddella, 2014;Raffaele et al, 2018). Natural surface crust can significantly reduce dust emission and soil erosion (Chepil, 1958;Zobeck, 1991;Zhang et al, 2008;Yan et al, 2015;Nield et al, 2016). In nature, an exposed soil surface usually forms a crust after cycles of saturation and insolation (Chen et al, 1980;Gomes et al, 2003).…”

“…High potential for dust emission exists from the salt-crusted surfaces typical of wet playas, and low potential exists from hard, compact surfaces that lack salt crusts (Reynolds et al, 2007). Furthermore, the types of salts that compose surface crusts influence emissivity (Nield et al, 2016). As mentioned in section 5.3, sulfate salts tend to be more emissive than chloride-carbonate salts, and consequently dust emitted from the AM-FLP area is dominated by sulfate compositions.…”
