SnowEx17 data contains snowpack relative permittivities and densities derived from Ground Penetrating Radar surveys and airborne lidar observations. NSIDC_CPRD published this data set, which covers Grand Mesa, Colorado, between 08 Feb 2017 and 25 Feb 2017. Parameters include two-way travel time, lidar-measured snow depth, calculated snow water equivalent, snow density, and relative permittivity.
Use Cases
- Model snow water equivalent based on lidar-measured snow depth and calculated SWE.
- Analyze snowpack density variations based on calculated snow density.
- Validate remote sensing algorithms using derived relative permittivity.
- Study snowpack structure using two-way travel time from GPR surveys.
Strengths
- Data integrates two remote sensing methods: Ground Penetrating Radar and airborne lidar.
- Parameters include calculated snow water equivalent, snow density, and relative permittivity.
- Temporal coverage is specific: 08 Feb 2017 to 25 Feb 2017.
- Geographic coverage is specific: Grand Mesa, Colorado.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
