SeaFlux: Standardized Air-Sea CO2 Flux Components for Surface pCO2 Products

SeaFlux provides components for calculating air-sea carbon dioxide fluxes using a standardized equation. The dataset includes sea surface pCO2 from a scaled climatology, atmospheric pCO2 from NOAA, solubility, and gas transfer velocities derived from multiple wind products. It was created by Luke Gregor at ETH Zurich to reduce methodological errors in flux calculations.

Use Cases

• Calculating global air-sea CO2 flux budgets based on the standardized flux equation.
• Comparing flux estimates derived from different wind products (CCMPv2, JRA55, ERA5, NCEP1, NCEP2).
• Analyzing the impact of sea ice fraction on regional CO2 exchange based on the OISST ice data.
• Studying the spatial and temporal variability of surface ocean pCO2 using the Landschützer climatology.
• Correcting atmospheric pCO2 for water vapor pressure using ERA5 mean sea level pressure data.

Strengths

• Uses a standardized flux calculation approach to reduce methodological inconsistencies.
• Integrates data from multiple authoritative sources, including NOAA, ERA5, OISST, and EN4.
• Provides multiple wind product options (CCMPv2, JRA55, ERA5, NCEP1, NCEP2) for gas transfer velocity.

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.
