SeaFlux: Harmonized Global Sea-Air CO2 Fluxes from Multiple Products

SeaFlux provides harmonized global sea-air carbon dioxide flux data calculated using a standardized approach. The dataset includes multiple components of the flux calculation, such as sea surface pCO2 from six products, gas transfer velocities from five wind products, atmospheric pCO2, and ice fraction. It was produced by Luke Gregor at ETH Zurich to reduce methodological inconsistencies in flux estimates.

Use Cases

• Modeling global ocean carbon uptake based on harmonized sea-air CO2 flux calculations.
• Assessing methodological uncertainty in flux estimates by comparing results from multiple pCO2 and wind products.
• Analyzing spatial and temporal patterns of ocean-atmosphere CO2 exchange using the provided gridded flux fields.
• Validating Earth system model outputs against a standardized observational flux product.

Strengths

• Uses a standardized calculation method to reduce errors from methodological differences.
• Integrates data from multiple sources, including six sea surface pCO2 products and five wind products.
• Provides all individual components of the flux equation, allowing for transparent error analysis.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Last update date is unknown; freshness unverified.
• Column-level documentation is absent; field semantics must be inferred after download.
