Supplementary Data for Aeolian Abrasion Chamber Particle Velocities

Supplementary files for "Quantification of particle velocities and energy regime in an aeolian abrasion chamber" by Joanna Bullard, last updated April 2026. The dataset includes 78.9 MB of files supporting a study that measured two-dimensional velocity components for 17 different sand samples in a laboratory abrasion chamber. Particle velocities and energy regimes were quantified using a laser Doppler anemometer for air inflow rates up to 14.9 m s⁻¹.

Use Cases

• Modeling particle energy and velocity distributions in saltation based on the reported velocity and energy measurements.
• Calibrating laboratory abrasion chamber simulations against natural saltation clouds using the provided velocity and energy comparisons.
• Analyzing the relationship between particle size and mean velocity under constant air inflow, as described in the study.

Strengths

• Includes data for 17 distinct sand samples, allowing for comparative analysis.
• Reports specific particle velocity ranges (0.01 to 3.2 m s⁻¹) and median velocities (0.29 to 0.56 m s⁻¹) for a defined air inflow rate.
• Quantifies total energy values ranging from 0.54 to 1.38 J kg⁻¹, providing concrete energy regime data.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Description metadata is limited; actual data quality requires manual inspection after download.
