BOREAS TE-07: Sap Flow and Transpiration in Boreal Forests

BOREAS TE-07 data contains sap flow measurements from boreal forest vegetation in Saskatchewan, Canada. The heat pulse method was used to monitor sap flow and estimate transpiration rates for aspen, black spruce, and mixed wood forests. Measurements were collected at multiple sites across three growing seasons from 1994 to 1996.

Use Cases

• Modeling canopy transpiration rates based on sap flow measurements and scaling procedures.
• Analyzing seasonal water use patterns in aspen, black spruce, and mixed wood forests.
• Comparing sap flow dynamics across different boreal forest sites (SSA-OA, MIX, SSA-OBS, Batoche).
• Validating remote sensing or hydrological models with ground-based transpiration estimates.

Strengths

• Data collection spans three growing seasons (1994, 1995, 1996), providing multi-year observations.
• Covers multiple boreal forest types (aspen, black spruce, mixed wood) and sites in Saskatchewan.
• Uses a specific, documented measurement method (heat pulse method for sap flow).

Limitations

• Column names and data structure are unknown, limiting immediate usability.
• Conflicting 'last updated' metadata between platforms (1996 vs. 2026).
• Specific file sizes and row counts are not provided.
