Spectral reflectance measurements were taken at each meter of the NIMS grid in Barrow, Alaska during the summer of 2012. The data was collected by SCIOPS using a Unispec DC spectrometer with a specific sensor angle and footprint. Measurements were taken from the edge of white boards aimed at plots located about 200 meters northeast of the ITEX dry sites.
Use Cases
- Modeling surface albedo and energy balance based on spectral reflectance data.
- Validating satellite-derived reflectance products based on ground-based spectrometer measurements.
- Studying vegetation and soil properties in Arctic tundra based on spectral signatures.
- Calibrating remote sensing instruments based on precise, localized spectral measurements.
Strengths
- Measurements were taken at each meter of the NIMS grid, suggesting systematic spatial coverage.
- Instrumentation and collection method are described, including a Unispec DC spectrometer and a specific sensor angle of 20 degrees.
- Geographic context is provided, situating the grid about 200 meters northeast of the ITEX dry sites in Barrow, Alaska.
Limitations
- Description metadata is limited; actual data quality requires manual inspection after download.
