SnowEx 2020 and 2021 campaigns provide snow depth values at a 0.5 m spatial resolution, derived from point cloud digital terrain models. Snow depths are available for February 2020 and March 2021 for multiple areas in Colorado, Idaho, and Utah. These data were produced alongside DEM and Vegetation Height data sets.
Use Cases
- Model snow water equivalent based on snow depth measurements.
- Validate satellite-derived snow cover products based on lidar-derived snow depth.
- Assess seasonal snowpack variability across mountainous regions based on multi-year data.
- Study snow accumulation and ablation patterns based on high-resolution terrain models.
Strengths
- Data has a 0.5 meter spatial resolution.
- Coverage includes multiple areas in Colorado, Idaho, and Utah.
- Data is available for two distinct time periods: February 2020 and March 2021.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
