BOREAS Understory Spectral Reflectance in Northern Manitoba

Spectral reflectance data were collected at the ground level across three boreal forest sites in Northern Manitoba (56°N, 98°W). This dataset was part of the Boreal Ecosystem-Atmospheric Study (BOREAS) TE-09 project, aiming to link understory light levels with airborne imagery for photosynthesis modeling. The project involved NASA and included canopy modeling, architecture measurements, and photometric readings.

Use Cases

• Calibrating airborne remote sensing imagery using ground-level spectral reflectance measurements.
• Modeling light availability and photosynthetic activity within boreal forest understories.
• Studying the relationship between canopy architecture and understory spectral properties.
• Integrating in-situ photometric data with high-resolution canopy models for ecosystem studies.

Strengths

• Data originates from the large, coordinated BOREAS study conducted by NASA.
• Measurements cover three distinct sites providing spatial replication.
• Dataset integrates multiple measurement types: spectral reflectance, canopy architecture, and photometry.

Limitations

• Key technical details like row count, file size, and specific column names are unavailable from all sources.
• There is a conflict on the last updated date: one source states 1994-07-31, while another lists a future date of 2026-03 13.
