Summer 2012 spectral reflectance measurements were taken at each meter of the NIMS grid in Atqasuk, Alaska. The data was collected using a Unispec DC spectrometer with fiber optics sensors mounted on a tripod. The organization SCIOPS published the dataset on NASA EarthData.
Use Cases
- Modeling vegetation indices based on spectral reflectance measurements.
- Analyzing spatial patterns of ground reflectance across a meter-gridded field site.
- Calibrating remote sensing instruments using the described 100% reflective white board reference scans.
- Studying Arctic ecosystem properties based on field-collected spectral data.
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 a tripod height of 1.62 meters.
- Reference scans were taken on a 100% reflective white board surface, which aids data calibration.
Limitations
- Description metadata is limited; actual data quality requires manual inspection after download.
- Last updated 2012-07-30 23:59:59.999000; freshness should be verified.
- Column-level documentation is absent; field semantics must be inferred after download.
