SeaFlux: Air-sea CO2 fluxes for surface pCO2 data products using a standardised approach

Fluxes calculated using standardised approach: \(F\text{CO}_2=K_0 \cdot K_w \cdot (p\text{CO}_2^\text{sea} - p\text{CO}_2^\text{atm})\ \cdot (1 - [ice])\).<br> We provide each of the components to this equation to reduce the potential for errors in fluxes due to methodological differences. \(p\text{CO}_2^\text{sea}\) is filled using a temporally scaled version of the Landschützer et al. (2020) climatology. \(K_0\) is calculated using the Weiss (1974) parameterization with EN4 salinity and OISST temperatures \(p\text{CO}_2^\text{atm}\) is calculated from NOAA's marine boundary layer product with ERA5 mean sea level pressure corrected for pH2O \([ice]\) is the ice fraction from the OISST product \(k_w\) is calculated for CCMPv2, JRA55, ERA5, NCEP1 and NCEP2 winds with each being scaled independently to 14-C bomb flux estimate of 16.5 cm/hr using the quadratic formulation by Wanninkhof (1992)
