Forest Observation System: Global In Situ Forest Biomass Reference Data

A global in situ forest biomass database provides aboveground biomass and canopy height estimates at a 0.25-hectare scale from permanent research plots worldwide. The Forest Observation System initiative maintains this dataset for calibrating and validating satellite remote sensing products. The live dataset is available from the FOS website.

Use Cases

• Calibrating wall-to-wall satellite remote sensing biomass maps based on the global plot network.
• Validating the accuracy of carbon loss and forest degradation estimates using ground-based reference data.
• Assessing renewable energy potential from forest biomass resources based on geolocated plot measurements.
• Developing climate change mitigation policies by providing reliable and comparable in situ data for greenhouse gas accounting.

Strengths

• Plot estimates are geolocated and derived at a standardized 0.25-hectare scale, allowing direct comparison with remote sensing measurements.
• Data includes associated uncertainties for biomass and canopy height estimates, supporting robust error analysis.
• The dataset is maintained as a live, international cooperation, suggesting ongoing updates and community input.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and total geographic coverage are unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
