SeaFlux: harmonised sea-air CO2 fluxes from surface pCO2 data products using a standardised approach
Fluxes calculated using standardised approach: \(F\text{CO}_2=K_0 \cdot K_w \cdot (p\text{CO}_2^\text{sea} - p\text{CO}_2^\text{atm})\ \cdot (1 - [ice])\). We provide each of the components to this equation to reduce the potential for errors in fluxes due to methodological differences. The netCDFs c...
