Transport mass and proportion data of soil wind-eroded dust from three dust source surfaces

我们从中国乌兰布沙漠的三个潜在尘埃源表面收集了未受干扰的土壤样本,包括移动沙丘、干涸的湖床和农田。通过风洞模拟和室内分析,我们测量了在 8 m·s-1、11 m·s-1 和 14 m·s-1 风速下这些表面排放的 PM2.5、PM10、PM63 和总沉积物的质量。此外,我们量化了 10 个近表面高度 (13-130 cm) 上细颗粒的比例和质量变化。该数据集包含用于分析 Ulan buh 沙漠及周边地区的沙尘排放和沙尘垂直剖面的 R 脚本和数据。这些脚本包括用于数据处理、可视化和统计分析的代码。数据包括在不同风速和表面条件下的粉尘排放和粉尘垂直剖面的测量。这些数据存放在这里是为了支持对不同表面的扬尘排放潜力和近地表传输模式的分析,确定区域扬尘事件中细颗粒物的主要来源,并强调农田防护林对扬尘控制的必要性。We collected undisturbed soil samples from the surfaces of three potential dust sources in the Ulan Buh Desert, China, including mobile sand dunes, dried lake beds and farmlands. Through wind tunnel simulations and laboratory analyses, we measured the mass of emitted PM2.5, PM10, PM63 and total sediment from these surfaces at wind speeds of 8 m·s⁻¹, 11 m·s⁻¹ and 14 m·s⁻¹. In addition, we quantified the proportion and mass variations of fine particles at 10 near-surface heights ranging from 13 cm to 130 cm. This dataset contains R scripts and data for analyzing dust emissions and dust vertical profiles in the Ulan Buh Desert and its surrounding regions. These scripts include codes for data processing, visualization and statistical analysis. The dataset includes measurements of dust emissions and dust vertical profiles under varying wind speeds and surface conditions. These data are deposited here to support analyses of dust emission potentials and near-surface transport patterns of different surfaces, identify the main sources of fine particulate matter in regional dust events, and highlight the necessity of farmland shelterbelts for dust emission control.
