Global and North American Carbon Cycle Model Driver Data

Global and North American environmental driver data standardized for carbon cycle model intercomparison. The dataset contains 3,152 netCDF-4 files providing gridded climatology variables, atmospheric CO2, nitrogen deposition, land cover, and soil characteristics from 1801 to 2010. It was compiled by the Oak Ridge National Laboratory Distributed Active Archive Center for the North American Carbon Program's Multi-Scale Synthesis and Terrestrial Model Intercomparison Project.

Use Cases

• Providing standardized precipitation, air temperature, and wind speed inputs to minimize inter-model variability in carbon flux simulations.
• Running sensitivity analyses of terrestrial biosphere models using time-varying atmospheric CO2 concentrations and nitrogen deposition data.
• Initializing land surface models with consistent global biome fraction and type classifications and regional C3/C4 grasses fractions.
• Assessing the impact of historical land-use and land-cover change on carbon budgets from 1801 onward.
• Incorporating soil characteristics and phenology data as static drivers for ecosystem process modeling.

Strengths

• Data were used by 22 terrestrial biosphere models for the MsTMIP project, demonstrating community validation and utility.
• Provides a long temporal record suitable for historical simulations from 1801 to 2010.
• Offers standardized, gridded collections at two spatial resolutions: global (0.5-degree) and regional North America (0.25-degree).
• Files are compliant with the Climate and Forecast (CF) metadata convention (version 1.4), ensuring interoperability.

Limitations

• Specific column names and the exact row count are not provided by any platform.
• Conflicting 'last updated' dates exist between sources: one lists 2010-12-31 and another lists 2026-03-12, creating uncertainty about data currency.
• The license is ambiguously listed as 'other-license-specified' without further details.
