Title

Surface and Meteorological Data of Protodune Dynamics at Medano Creek Area, Great Sand Dunes National Park, Colorado, USA on 3rd April 2023

Abstract

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.

Quality and validity

Lineage

Leica P20 TLS was used to collect the topographic measurements. The scan resolution was 3.1 mm at 10 m. The local coordinate system has been orientated to the wind direction. The dataset has been extracted in 15 boxes to make the data manageable and details of the lower x and y coordinates for each box are included in the dataset. 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, upwind of the scanned area. The Wenglors were at heights of 0.02 and 0.05 m and the Sensit was positioned at the ground surface. See Delorme et al. (2023; doi:10.1029/2022GL101553) for more details of similar methodology.
