Separating emitted dust from the total suspension in airflow based on the characteristics of PM10 vertical concentration profiles on a Gobi surface in northwestern China
《Journal of Arid Land》2022年第6期589-603,共15页ZHANG Chunlai WANG Xuesong CEN Songbo ZHENG Zhongquan Charlie WANG Zhenting 
This work was supported by the National Natural Science Foundation of China(41630747).
During aeolian processes,the two most critical factors related to dust emissions are soil particle and aggregate saltation,which greatly affect the vertical profiles of near-surface dust concentrations.In this study,w...
