ABoVE: AVIRIS-3 Imaging Spectroscopy for Alaska and Canada, 2023

AVIRIS-3 airborne sensor data measuring reflected radiance at 7.4-nm intervals across the Visible to Shortwave Infrared spectrum from 390-2500 nm. This dataset includes L1B radiance and L2A surface reflectance imagery collected over Alaska and northwestern Canada in 2023 for NASA's Arctic-Boreal Vulnerability Experiment (ABoVE) project. The imagery is provided in ENVI format with GeoJSON boundaries.

Use Cases

• Classifying land cover and vegetation types based on hyperspectral reflectance signatures.
• Monitoring changes in Arctic and boreal ecosystems based on multi-sensor airborne campaign data.
• Developing spectral indices for environmental variables based on 7.4-nm interval measurements.
• Calibrating or validating satellite-derived surface reflectance products based on airborne L2A data.

Strengths

• Data collected by NASA's AVIRIS-3 instrument, a spectral mapping system with 1234 pixels per scan line.
• Covers the Visible to Shortwave Infrared (VSWIR) spectral range from 390-2500 nm.
• Imagery is part of a coordinated multi-sensor airborne campaign involving eleven different aircraft teams.
• Ground sampling distances range from 12 meters down to sub-meter, depending on altitude.

Limitations

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