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.
