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.

The scan resolution varied between 0.8 and 3.1 mm at 10 m. The local coordinate system has been orientated to the wind direction. The dataset has been extracted in boxes to make the data manageable and details of the lower x and y coordinates for each box are included in the dataset. The CSAT 3D sonic anemometer was positioned 0.24 m above the surface. The Sensit was positioned at the ground surface. The Wenglors were at 0.02 and 0.05 m above the surface. See Delorme et al. (2023; doi:10.1029/2022GL101553) for more details of similar methodology.
