North American Carbon Flux Model at 8-km Resolution for 2004

Modeled carbon flux estimates at 8-km spatial resolution over North America for the year 2004. The dataset includes five annual and two daily flux components: net ecosystem exchange, net ecosystem production, stream evasion, emissions from harvested products, and biomass burning. It was produced by NASA using the CarbonTracker modeling system and is provided in seven NetCDF files.

Use Cases

• Validating terrestrial biosphere models by comparing simulated NEP and NEE against the modeled 8-km estimates.
• Analyzing spatial patterns of carbon emissions from biomass burning and harvested products across North America.
• Assessing the contribution of inland water systems to regional carbon budgets using the stream evasion flux component.
• Conducting bottom-up carbon accounting by integrating the five distinct flux components provided in the dataset.

Strengths

• Provides a multi-component carbon budget with five distinct flux types, enabling detailed analysis.
• Offers high spatial resolution (8-km) for the entire North American continent.
• Includes both annual and daily temporal resolutions for NEP and stream evasion fluxes.

Limitations

• Data is limited to a single year (2004), reducing utility for trend analysis.
• Conflicting metadata exists: one source lists a last updated date of 2026-03-13, while another indicates the data year is 2004.
• Specific row counts, file sizes, and detailed column names are not provided across sources.
