Land-use Fluxes from Global Models and National Inventories for 42 Countries

42 countries with managed forest areas exceeding 10 million hectares are covered. The dataset compares average CO2 fluxes from 2001-2020 derived from three bookkeeping models, 17 dynamic global vegetation models, and national greenhouse gas inventories. It was compiled by Giacomo Grassi of the European Commission for a submitted study.

Use Cases

• Benchmark global carbon model outputs against national inventory reports based on the provided CO2 flux data.
• Analyze discrepancies in forest land and deforestation flux estimates between different methodological approaches.
• Assess the carbon budget for large managed forest areas across 42 countries.
• Validate land-use change emissions from organic soils, cropland, and grassland using multi-source data.

Strengths

• Data aggregates results from three bookkeeping models and 17 dynamic global vegetation models.
• Focuses on 42 countries with managed forest areas greater than 10 million hectares.
• Provides a 20-year average (2001-2020) for CO2 fluxes from multiple sources.

Limitations

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