Snow Microstructure and Compression Data with 3D CT Images

Unconfined compression experiments and 3D computed tomography (CT) imaging were performed on sintered rounded grain snow and spherical model snow. The data was created for calibrating numerical models like discrete element models (DEM) and was last updated in 2019. The dataset originates from ENVIDAT and is hosted on NASA's Earthdata platform.

Use Cases

• Calibrating discrete element models (DEM) based on geometrically simplified spherical model snow.
• Investigating the relationship between sintering time and microstructural properties based on the described experimental variation.
• Analyzing 3D microstructure reconstructions based on CT images of cylindrical snow samples.
• Studying the mechanical properties of snow under unconfined compression based on the experimental data.

Strengths

• Includes 3D CT images allowing for complete reconstruction of experimental samples.
• Experimental design systematically varies sintering time and density to create microstructural variation.
• Spherical model snow provides geometrically simplified, well-defined microstructures for model calibration.

Limitations

• Last updated 2019-01-01 00:00:00; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file formats are unknown, which may limit suitability assessment.
