Surface and meteorological data of protodune dynamics at Medano Creek, Great Sand Dunes National Park and Preserve, Colorado, USA in March and April 2023

This dataset includes raw point cloud data from repeat terrestrial laser scans (TLS) for measuring early-stage protodunes developing, migrating and eroding on a moist surface in the Medano Creek Area, Great Sand Dunes National Park and Preserve, Colorado, USA. As well as the TLS data, additional measurements include wind speed with a CSAT 3D sonic anemometer and sediment transport using a Sensit and Wenglor fork sensors.

本数据集涵盖源自重复地面激光扫描（TLS）的原始点云数据，用于实测美国科罗拉多州大沙丘国家公园及保护区梅达诺溪区域潮湿地表上发育、迁移并遭到侵蚀的早期原型沙丘（protodunes）。除地面激光扫描数据外，数据集还包含额外测量结果：采用CSAT三维超声风速仪获取的风速数据，以及借助Sensit与Wenglor叉型传感器采集的泥沙输运数据。
