BOREAS Foliage Nitrogen and Photosynthetic Capacity Data

The BOREAS TE-09 team collected data on the spatial and temporal relationship between foliage nitrogen concentration and photosynthetic capacity for three boreal tree species: black spruce, jack pine, and aspen. Measurements were taken from June to September 1994 to support modeling of vertical carbon fixation distribution in boreal forests. This dataset is managed by ORNL_CLOUD and appears on multiple platforms, including NASA Earthdata and Data.gov.

Use Cases

• Modeling the vertical distribution of carbon fixation in boreal forest canopies.
• Analyzing the relationship between foliage nitrogen concentration and photosynthetic capacity across species.
• Studying seasonal variation in leaf chemical and photosynthetic properties from June to September.
• Comparing physiological traits between black spruce, jack pine, and aspen in a boreal context.

Strengths

• Data covers three key boreal forest species: black spruce, jack pine, and aspen.
• Provides temporal coverage across a full growing season (June to September 1994).
• Cross-platform presence on NASA Earthdata and Data.gov indicates established use in the scientific community.

Limitations

• Specific column names, row counts, and file sizes are not provided by any source.
• Conflicting 'last updated' dates exist between sources (1994-09-19 vs. 2026-03 13).
