SnowEx23 Apr23 IOP Snow Surface Imagery V001 contains 54 photographs of snow surfaces collected during the NASA SnowEx23 field campaign near Fairbanks, Alaska. Photos were acquired in April and May 2023 at three study sites representing intact boreal forest, burned forest, and open meadows. The dataset provides visual context for concurrent ground-based hyperspectral, snow sample, UAV, and satellite observations.
Use Cases
- Interpret spectral variability of snow surfaces based on concurrent ground measurements mentioned in the description
- Analyze snow surface characteristics across different landcover conditions including boreal forest and meadows
- Provide visual context for calibrating or validating airborne and satellite hyperspectral data
- Study snowpack evolution in boreal and recently burned forest environments during spring
Strengths
- 54 photographs provide direct visual context for snow surface measurements
- Data collected concurrently with hyperspectral spectrometer, snow samples, UAV, AVIRIS-NG, and satellite observations
- Three distinct study sites covering intact boreal forest, recently/historically burned forest, and open meadows
Limitations
- Row count is unknown, which may limit suitability assessment
- Column-level documentation is absent; field semantics must be inferred after download
- Data may reflect geographic bias inherent to nasa_earthdata, being limited to sites near Fairbanks, Alaska
