This dataset includes raw point cloud data from repeat terrestrial laser scans (TLS) for early-stage protodunes developing on a moist sandy surface in the Medano Creek area at Great Sand Dunes National Park, Colorado, USA under very strong winds. 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 and Wenglor fork sensors.
