BOREAS Photosynthetic Response Data for Boreal Tree Species

Photosynthetic response data for black spruce, jack pine, and aspen were collected by the BOREAS TE-09 team. Measurements include leaf and shoot-level photosynthesis responses to CO2, temperature, and light, stomatal conductance, and shoot water potentials. The dataset originates from field campaigns during three Intensive Field Campaigns in 1994 in the Northern Study Area.

Use Cases

• Modeling photosynthetic light and CO2 response curves using incident PAR and intercellular CO2 concentration measurements.
• Analyzing stomatal behavior under varying atmospheric conditions using vapor pressure difference and conductance data.
• Studying plant water relations and drought stress via controlled laboratory measurements of shoot water potential.
• Comparing physiological traits, such as temperature response of photosynthesis, across three key boreal tree species.

Strengths

• Data covers three distinct boreal tree species: black spruce, jack pine, and aspen.
• Includes both field measurements from three 1994 IFCs and controlled laboratory experiments.
• Cross-platform presence on NASA EarthData and Data.gov indicates established scientific use.

Limitations

• Key quantitative details like row count, file size, and specific column names are unavailable from all sources.
• Conflicting 'last updated' dates exist between platforms (1994-09-19 and 2026-03-13), creating uncertainty about metadata maintenance.
