Global Peatland Carbon Balance and Land Use Emissions Over 11,000 Years

ORNL_CLOUD provides a 11,000-year time series of global peatland carbon balance and land-use change CO2 emissions. The dataset combines empirical data from 64 dated peat cores with LPX-Bern model simulations and published land-use scenarios (HYDE 3.1, HYDE 3.2, KK10). This synthesis aims to constrain the range of past anthropogenic emissions and their role in the carbon cycle.

Use Cases

• Calibrating Earth system models using historical peatland carbon balance data.
• Analyzing the contribution of pre-industrial land-use change to Holocene atmospheric CO2 trends.
• Comparing different anthropogenic land-use change emission scenarios (HYDE and KK10) over millennia.
• Studying the relationship between peatland distribution dynamics and long-term carbon sequestration.

Strengths

• Integrates empirical data from 64 dated peat cores for model validation.
• Covers an extensive 11,000-year temporal range of the Holocene.
• Combines multiple model estimates and land-use scenarios to narrow emission uncertainties.

Limitations

• Specific column names and row counts are not provided by any platform.
• Conflicting 'last updated' dates exist (2001 vs. 2026), creating uncertainty about data currency.
• The exact license terms under 'other-license-specified' are not detailed.
