Surface and Meteorological Data of Ripples, Saltation and Protodune Dynamics at Medano Creek, Great Sand Dunes National Park and Preserve, Colorado, USA in March and April 2023
This dataset includes raw point cloud data from repeat terrestrial laser scans (TLS) for measuring ripple and saltation dynamics as well as early-stage protodunes migrating and eroding on a moist surface in the Medano Creek Area, Great Sand Dunes National Park and Preserve, Colorado, USA. 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.

Leica P50 and P20 TLS was used to collect the topographic measurements. 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. Along with the data, c codes are included to process the raw point clouds and Matlab scripts to process the gridded data to calculate various ripple and saltation metrics.
