BOREAS HYD-01: Under-Canopy Precipitation in Boreal Forests

Under-canopy precipitation measurements were collected from 1994 to 1997 at multiple flux tower sites in the Northern and Southern Study Areas of the BOREAS project. These data, which coincide with volumetric soil moisture measurements, quantify water that falls through the forest canopy to the ground or moss layer. The dataset supports research on the hydrological cycle and canopy interception processes in boreal ecosystems.

Use Cases

• Modeling canopy interception and throughfall based on site-specific precipitation measurements.
• Analyzing temporal trends in soil moisture coincident with precipitation events.
• Comparing hydrological dynamics between different boreal forest sites (e.g., NSA-OJP, SSA-YJP).

Strengths

• Multi-year temporal coverage from 1994 to 1997.
• Measurements collected at multiple, specific flux tower sites (e.g., NSA-OJP, SSA-OA).
• Data coincides with related volumetric soil moisture measurements.

Limitations

• Column names and exact data structure are unknown, limiting immediate usability.
• Conflicting metadata: one source lists data collection ending in 1996, another in 1997.
• Sparse technical metadata regarding measurement units, frequency, and file formats.
