NACP Site Synthesis: Original Terrestrial Biosphere Model Outputs

Twenty-four distinct terrestrial biosphere models contributed estimates for six core ecosystem variables across 47 eddy covariance flux tower sites in North America. The data represents a benchmark for model inter-comparison within the North American Carbon Program, with outputs standardized into NetCDF format from original submissions. A related processed dataset provides gap-filled observations and aggregated time steps for direct evaluation.

Use Cases

• Benchmarking terrestrial biosphere model performance against gap-filled tower observations.
• Analyzing inter-model variability in estimates of gross primary productivity and net ecosystem exchange.
• Studying ecosystem respiration and energy flux patterns across diverse North American biomes.
• Comparing model-derived leaf area index with remote sensing or field measurements.

Strengths

• Includes outputs from 24 distinct terrestrial biosphere models, enabling robust inter-comparison.
• Covers 47 eddy covariance flux tower sites across multiple North American ecosystems.
• Data was standardized into consistent NetCDF files following a formal synthesis protocol.

Limitations

• Specific column names and row counts are not provided in the available metadata.
• Conflicting last-updated dates exist between platforms (2007 vs. 2026), creating uncertainty about data currency.
• The original data format is described as a mix of NetCDF and text files within ZIP archives, which may require unpacking and format handling.
