ABoVE: Tundra Plant Community Reflectance Spectra across Northern Alaska

Full-spectrum reflectance measurements of tundra plant communities and individual species collected during the 2017 and 2018 summer field seasons. The data include plot-level and leaf-level scans across multiple sites in northern Alaska, calibrated using a white reference panel. Measurements follow the Ecological Spectral Information System (EcoSIS) Spectral Library structure and were collected by the National Aeronautics and Space Administration.

Use Cases

• Classifying tundra vegetation types based on spectral signatures.
• Developing models for plant community composition from remote sensing data.
• Calibrating satellite or airborne sensor data using ground-level spectral measurements.
• Studying spectral properties of individual Arctic plant species.

Strengths

• Spectral range covers 350-2500 nm, providing full-spectrum data.
• Data collection follows established EcoSIS Spectral Library methods.
• Includes both plot-level (1 m2) community data and leaf-level species-specific scans.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
