SeaFlux: Standardized Air-Sea CO2 Flux Components for Multiple Wind Products

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

Use Cases

• Calculate standardized CO2 fluxes based on the provided flux equation components.
• Compare air-sea CO2 flux estimates derived from different wind products (CCMPv2, JRA55, ERA5, NCEP1, NCEP2).
• Analyze the impact of sea ice fraction on CO2 exchange using the provided icefrac variable.
• Study spatial and temporal patterns of ocean carbon uptake using the filled sea-surface pCO2 data.

Strengths

• Uses a standardized calculation approach to reduce methodological differences in flux estimates.
• Provides pre-calculated product terms (sf_prod_WIND) for each wind product to reduce download size.
• Integrates data from multiple authoritative sources including NOAA, ERA5, EN4, and OISST.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred from the description.
• Last update date is unknown; freshness unverified.
