Saltation Activity on Non-Dust Days in the Taklimakan Desert, China

Dust aerosols persistently affect nearly all landscapes worldwide, and the saltation activity caused by dusty weather (e.g., dust days) releases considerable amounts of aerosol into atmosphere. Nevertheless, dust-induced may also occur on non-dust days. To date, few studies have investigated characteristics Moreover, contribution days to total remains ambiguous. This study comprehensively investigates Specifically, we analyze influence utilizing saltation, atmospheric, soil, (i.e., PM10 optical depth), record data obtained from Taklimakan Desert, China, between 2008 2010. Our results show that lower temperature, vapor pressure, soil moisture reduces threshold velocity (5.9 m/s) more compared (6.5 m/s). Furthermore, regarding wind speed, relatively strong monthly occurs March August, daily 9:00 16:00. Although only contribute 18.5% 7.7% time count, respectively, both significantly aerosols. Therefore, effect cannot be undervalued, particularly while performing studies.
