Great Sand Dunes National Park in Colorado, USA, is the location for this dataset of repeat terrestrial laser scans and meteorological measurements from April 5-11, 2022. It includes raw point cloud data for dry rippled and moist sandy surfaces, along with wind speed from a CSAT 3D sonic anemometer and sediment transport from Sensit and Wenglor fork sensors. The data was collected under NERC Grant NE/R010196/1 and is associated with the British Geological Survey.
Use Cases
- Modeling ripple formation and migration based on high-resolution surface scans.
- Correlating sediment transport rates with measured wind speed and direction.
- Analyzing surface moisture effects on sand mobility using scans of moist versus dry surfaces.
Strengths
- Data collection is precisely dated to April 5-11, 2022.
- Includes multiple sensor types (TLS, anemometer, sediment transport sensors) for a multi-faceted view of the process.
- Associated with a specific research grant (NERC Grant NE/R010196/1) and the British Geological Survey.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count and file size are unknown, which may limit suitability assessment.
- The dataset's last update is listed as 2026-05-28; freshness should be verified.
