Summer 2011 spectral reflectance measurements taken at each meter of the NIMS grid in Barrow, Alaska. The data was collected using a Unispec DC spectrometer with fiber optics, mounted on a tripod at a height of 1.62 meters. The organization SCIOPS published the dataset on August 10, 2011.
Use Cases
- Analyze surface reflectance patterns based on meter-by-meter grid measurements.
- Model spectral signatures of Arctic tundra based on sensor data collected at a 20-degree angle.
- Validate remote sensing products based on ground-level spectral reflectance measurements.
- Study seasonal changes in vegetation or soil properties based on summer 2011 data.
Strengths
- Measurements taken at each meter of a defined grid, suggesting systematic spatial coverage.
- Instrumentation details are specified, including a Unispec DC spectrometer and tripod height of 1.62 meters.
- Sensor footprint and angle are documented, with a calculated footprint of 50-60 cm and a sensor angle of 20 degrees.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Last updated 2011-08-10 23:59:59.999000; freshness should be verified.
- Row count is unknown, which may limit suitability assessment.
