McMurdo Sound, Antarctica, October-December 2022, contains processed UAV-collected data on snow surface temperature, topography, and irradiance. The dataset includes orthomosaics of RGB imagery, digital elevation models, thermal infrared images, and point measurements of radiation and atmospheric parameters. It was collected using a DJI Matrice 30T UAV and published by ENVIDAT.
Use Cases
- Modeling solar irradiance distribution on sea ice based on terrain-corrected radiative transfer calculations.
- Analyzing spatial variability of snow surface temperature based on thermal camera imagery.
- Mapping snow topography and roughness based on UAV-derived digital elevation models.
- Correlating atmospheric conditions with surface properties based on automated weather station data.
- Validating radiative transfer models based on measured shortwave and longwave radiation components.
Strengths
- Thermal camera imagery has a specified accuracy of ±2 °C or ± 2%.
- GNSS data includes high-precision location information (latitude, longitude, ellipsoidal height).
- Data collection used specialized equipment suitable for polar conditions (temperature range from -20 to +50 °C).
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/temporal bias inherent to nasa_earthdata.
