Short summary
In spite of the tremendous efforts, many questions remain unanswered regarding dust emission mechanisms. A series of wind tunnel experiments are carried out on dust emissions from different soil surfaces to better understand relevant mechanisms. Here are some interesting results that demonstrate the importance of surface renewal mechanism, which was normally neglected in previous research and is strongly recommended to be considered in future dust models.
