Surface and Meteorological Data of Protodune Dynamics at Helga's Interdune Area, Gobabeb, Namib Desert, Namibia, 12th September 2023

This dataset includes raw point cloud data from repeat terrestrial laser scans (TLS) for early-stage protodunes migrating and eroding on a gravel surface in the Helga's Interdune Area, Gobabeb, Namib Desert, Namibia. As well as the TLS data, additional nearby measurements of the wind speed through a CSAT 3D sonic anemometer and sediment transport using a Sensit along with sediment trap data downwind of the focus protodune.

本数据集包含来自重复地面激光扫描（TLS）的原始点云数据，扫描场景为纳米比亚纳米布沙漠戈巴布赫尔加沙丘间区域内砾石表面上发生迁移与侵蚀的早期雏形沙丘（protodunes）。除上述TLS数据外，本数据集还涵盖配套的原位辅助测量数据：通过CSAT三维超声风速仪获取的近场风速数据、采用Sensit设备采集的泥沙输送数据，以及针对目标雏形沙丘下风侧的沉积物捕集器观测数据。
