The Snowflake Measurement and Analysis System (SMAS) dataset from the University of Connecticut reconstructs the three-dimensional structure of snowflakes using seven high-resolution cameras. It contains BMP images and a CSV file with data from January 14, 2023 to March 21, 2024. The dataset is hosted by NASA's GHRC DAAC.
Use Cases
- Analyze snowflake morphology based on multi-view photographs
- Develop models for precipitation microphysics based on 3D particle structure
- Validate remote sensing snowfall retrievals based on in-situ particle measurements
- Train computer vision models for particle segmentation and classification
Strengths
- Uses seven high-resolution cameras for 3D reconstruction
- Can measure and analyze multiple snowflakes simultaneously
- Data spans over a year from January 2023 to March 2024
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
- Data may reflect temporal bias inherent to the 2023-2024 collection period
