SeaFlux: harmonised sea-air CO2 fluxes from surface pCO2 data products using a standardised approach

Description

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 contain the following data:  fgco2_all_winds_products: the sea-air CO2 flux for all spCO2 products (6) and kws from all wind products (5).  solWeis74:  \(K_0\)  is calculated using the Weiss (1974) parameterization with EN4 salinity and OISST temperatures  kw_quadratic_scaled: \(k_w\)  is calculated for winds with each being scaled independently to 14-C bomb flux estimate of 16.5 cm/hr using the quadratic formulation by Wanninkhof (1992). CCMPv2 ERA5 JRA55 NCEP1 NCEP2 spco2_SOCOM_unfilled: \(p\text{CO}_2^\text{sea}\) downloaded from various sources contains the following products: CMEMS_FFNN CSIR_ML6 JENA_MLS JMA_MLR MPI_SOMFFN NIES_FNN spco2_filler: scaled version of the Landschützer et al. (2020) climatology used to fill missing regions of spco2_SOCOM_unfilled pco2atm: \(p\text{CO}_2^\text{atm}\) is calculated from NOAA's marine boundary layer product with ERA5 mean sea level pressure corrected for pH2O ice: \([ice]\)  is the ice fraction from the OISST product area_ocean: the surface area of the ocean including fractional area of the coastal regions Units are listed in the metadata of each of the netCDF variables.
