本数据集研究民勤地区不同高度处的风速变化。数据文件名称：民勤沙尘暴期间不同下垫面下近地表风速沿高度分布.dat，包含1个表：（1）民勤沙尘暴期间不同下垫面下近地表风速沿高度分布，包含了三个不同高度处测得的风速等指标。\n本数据表共有十个字段：Ux1，0.5米高度处x方向风速；Uy1，0.5米高度处y方向风速；Uz1，0.5米高度处z方向风速；wnd1_spd，0.5米高度处平均风速；wnd1_dir，0.5米处风向；Ux2，1米高度处x方向风速；Uy2，1米高度处y方向风速；Uz2，1米高度处z方向风速；wnd2_spd，1米高度处平均风速；wnd2_dir，1米高度处风向。“Ux1”单位：m/s，其他代表风速的字段其单位也是m/s\n“wnd1_dir”和“wnd2_dir”单位： °。
