11 snow pits from the SnowEx 2023 NASA field campaign Intensive Observation Period (March 2023) were analyzed using microcomputed tomography. The data set includes two- and three-dimensional microstructural analysis, binary images of sub-sample scans, and raw instrument data. Snow containers were collected at 6 pits in approximately 17 cm intervals, with 5-8 discrete containers per pit.
Use Cases
- Develop models for snow density and thermal conductivity based on three-dimensional microstructural analysis.
- Validate remote sensing snow property estimates using ground-truth microstructure data.
- Analyze snow layer stratigraphy and metamorphism based on scans from overlapping container samples.
- Train machine learning models to classify snow types from binary image scans of sub-sections.
Strengths
- Data originates from a structured NASA field campaign (SnowEx 2023) with a documented Intensive Observation Period.
- Includes both raw instrument data and processed 2D/3D analyses for 11 snow pits.
- Sampling protocol is detailed, with containers collected at approximately 17 cm intervals and 5-8 containers per pit.
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.
