Spectral reflectance measurements were taken at each meter of the NIMS grid in Atqasuk, Alaska during the summer of 2012. The instrumentation used was a Unispec DC spectrometer with fiber optics, positioned on a tripod at a height of 1.62 meters. The dataset was collected by SCIOPS and last updated on August 18, 2012.
Use Cases
- Analyze vegetation spectral signatures based on reflectance measurements from meter-grid plots.
- Model surface albedo or reflectance properties based on calibrated scans from a 100% reflective white board reference.
- Study spatial heterogeneity of ground cover within the ITEX research area based on the grid's proximity to dry sites.
Strengths
- Measurements were taken at each meter of a defined grid, suggesting systematic spatial coverage.
- Instrumentation details are provided, including a Unispec DC spectrometer and tripod height of 1.62 meters.
- Reference scans were taken on a calibrated 100% reflective white board surface.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
