Experimental data of Large Effects of Particle Size Heterogeneity and Measurement Method on Dynamic Saltation Threshold

There are the experimental data we conducted in a wind tunnel in Lanzhou University. And we present the original data about wind velocitys U [m/s] and corresponding measuring locations H above the sand bed [cm] with different sand size distribution here.本数据集收录了我们于兰州大学风洞内开展的实验相关数据。本次公开的原始数据涵盖不同粒径分布（sand size distribution）条件下，沙床上方的风速U（单位：米每秒，m/s）及其对应的测量高度H（单位：厘米，cm）。
