Spectral reflectance measurements were taken at each meter of the NIMS grid in Imnavait, Alaska during the summer of 2012. The data was collected using a Unispec DC spectrometer with fiber optics, mounted on a tripod at a height of 1.62 meters, resulting in a calculated footprint of 50-60 cm per scan. The dataset was last updated on July 30, 2012.
Use Cases
- Model vegetation health and biomass based on spectral reflectance measurements.
- Analyze spatial patterns of surface reflectance across a meter-gridded plot.
- Validate satellite-derived reflectance data using ground-based spectrometer readings.
- Study seasonal changes in Arctic tundra surface properties during summer 2012.
Strengths
- Ground-based measurements provide high-resolution spatial data at each meter of the grid.
- Instrumentation details are specified, including a Unispec DC spectrometer and a tripod height of 1.62 meters.
- Reference scans were taken on a 100% reflective white board surface for 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.
