BOREAS TF-09: Foliar Carbon and Water Vapor Fluxes

From 07-April through 23-November-1996, the BOREAS TF-09 team measured carbon dioxide and water vapor fluxes from foliage at the SSA-OBS site. This dataset provides branch-level gas exchange data for the Boreal Ecosystem-Atmosphere Study (BOREAS). The time-series measurements support analysis of vegetation-atmosphere interactions in a boreal forest environment.

Use Cases

• Modeling net ecosystem exchange based on direct foliar flux measurements.
• Studying seasonal patterns of plant gas exchange from April to November.
• Analyzing the relationship between leaf characteristics and carbon/water vapor fluxes.
• Validating remote sensing data for boreal forest productivity.
• Comparing branch-level flux data with tower-based eddy covariance measurements.

Strengths

• Provides a continuous, nearly eight-month time series from April to November 1996.
• Collected as part of the large-scale, multi-disciplinary BOREAS campaign, ensuring contextual richness.
• Cross-platform presence on Data.gov and NASA Earthdata signals importance and curation.

Limitations

• Column names and exact data structure are unknown, limiting immediate usability.
• Metadata conflicts: Data.gov lists a 2026 update date, while NASA Earthdata shows a 1996 date, creating uncertainty about provenance.
• Dataset size, row count, and specific file formats within the ZIP archives are not detailed.
