Surface and Meteorological Data of Protodune Dynamics at Helga's Interdune Area, Gobabeb, Namib Desert, Namibia on 13th September 2022 (NERC Grant NE/R010196/1)
This dataset includes raw point cloud data from repeat terrestrial laser scans (TLS) for a field of protodunes that initiated and developed on a desert gravel interdune surface close to Helga's dune at Gobabeb, Namibia. As well as the TLS data, additional measurements of the wind speed through a CSAT 3D sonic anemometer and sediment transport using a Sensit.
A Leica P20 TLS was used to collect the topographic measurements. It scanned the full 360 degree surface to measure the whole field of protodunes at 3.1 mm at 10 m resolution. A co-located Leica P50 TLS also collected data at the same resolution and a smaller section over the closer bedforms is included in this dataset. Both TLS have been placed in the same local coordinate system and orientated to the wind direction. Details on the specific scan times for each TLS are included in the dataset. The CSAT 3D sonic anemometer was positioned 0.24 m above the surface.
