Description
Fluxes calculated using the standardized 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 netCDF files contain the following data:
- fgco2_all_winds_products: the sea-air CO2 flux for all spCO2 products (6) and kw from all wind products (5).
- fgco2_global: the globally integrated sea-air CO2 fluxes for all spCO2 products (6) and kw from all wind products (6)
- 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 a 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 the fractional area of the coastal regions
Units are listed in the metadata of each of the netCDF variables.
