Snow pit data from 13 excavations during the NASA SnowEx23 field campaign near Fairbanks, Alaska. The data was collected in April 2023 across three sites: Caribou/Poker Creek Research Watershed, Farmer’s Loop/Creamers Field, and Delta Junction. Measurements were processed according to standard NASA SnowEx methodology to support analysis of snow spectra.
Use Cases
- Validate and calibrate hyperspectral snow reflectance models based on concurrent spectrometer transects.
- Analyze snow microstructure and water content features mentioned in the description.
- Support studies of snow properties across boreal forests, burned forests, and open meadows.
- Train ML models to predict snow characteristics from remote sensing data using ground-truth pit measurements.
Strengths
- Data from 13 snow pits provides multiple ground-truth points.
- Collection was concurrent with hyperspectral measurements from NEON towers, drones, AVIRIS-NG, and satellites, enabling cross-validation.
- Standardized methodology aligns with other SnowEx 2023 datasets.
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 geographic bias inherent to nasa_earthdata, focusing on three sites near Fairbanks, Alaska.
