BOREAS BIOME-BGC Model Simulations of Carbon and Water Fluxes

NASA's BIOME-BGC model simulated daily water and carbon budgets for BOREAS tower flux sites during 1994. The dataset contains input and output files in tabular ASCII format, estimating variables like gross primary production, respiration, evapotranspiration, and soil moisture. This investigation supports analysis of biogeochemical and hydrologic processes in boreal forest ecosystems.

Use Cases

• Calibrating and validating terrestrial ecosystem process models against tower flux site data.
• Analyzing daily carbon flux components like gross primary production and net ecosystem exchange.
• Studying hydrologic budgets including evaporation, transpiration, and soil moisture dynamics.
• Investigating seasonal patterns of snow cover and its impact on ecosystem processes.
• Comparing modeled biogeochemical outputs across different forest sites within the BOREAS study area.

Strengths

• Model outputs are based on a well-cited, general ecosystem process model (BIOME-BGC).
• Provides daily estimates for a full year (1994) at multiple BOREAS research sites.
• Simulates a wide range of interconnected carbon and water cycle variables.

Limitations

• Critical metadata conflicts exist: 'last updated' dates differ significantly between Data.gov (2026) and NASA Earthdata (1994).
• Specific row counts, file sizes, and detailed column names are not provided by any source.
• Data format is described as tabular ASCII, but exact structure and accessibility are unclear.
