SnowEx20-21 QSI Lidar Snow Depth 3m UTM Grid V001 provides snow depth values derived from point cloud digital terrain models. NSIDC_CPRD produced the data for February 2020 and March 2021 across multiple areas in Colorado, Idaho, and Utah. The data set is part of the SnowEx 2020 and 2021 campaigns.
Use Cases
- Validate snow depth models based on lidar-derived terrain models.
- Analyze spatial snow distribution patterns based on 3-meter resolution grids.
- Assess snowpack changes over time based on February 2020 and March 2021 data.
- Integrate snow depth data with DEM and vegetation height datasets mentioned in the description.
Strengths
- Provides snow depth data at a 3.0 meter spatial resolution.
- Covers multiple areas in Colorado, Idaho, and Utah.
- Includes data 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.
- Data may reflect geographic bias inherent to nasa_earthdata.
