As well as the TLS data, additional measurements include wind speed with a CSAT 3D sonic anemometer and sediment transport using a Sensit sensor.

The scan resolution varied between 0.8 and 3.1 mm at 10 m. The local coordinate system has been orientated to the dominant wind direction of 185o. 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. Data collected over several months were merged using three fixed targets with a mean absolute error of 1 mm. Alongside the whole surface measurements between September and December, several high resolution temporal measurements were collected on the 11th September. The CSAT 3D sonic anemometer was positioned 0.24 m above the surface. The Sensit was positioned at the ground surface. See Delorme et al. (2023; doi:10.1029/2022GL101553) for more details of similar methodology.
