| Summary: | See the additional notes for updates on the 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 ( note that only bold names have been updated in v2023 ): 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) sol: \(K_0\) is calculated using the Weiss (1974) parameterization with EN4 salinity and OISST temperatures kw: \(k_w\) 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 : \(p\text{CO}_2^\text{sea}\) ... : version 2023.01: released alongside the GCBv2023. Note that I have not provided NCEPv2 since this was dropped during the analysis of the paper. Further, the salinity for the solubility is the same as that used in OceanSODA-ETHZ (see the documentation of that product). Temperature is still NOAA's OISST. I do not provide pco2atm but rather fco2atm since the GCB now requests fco2 instead of pco2. Note that the alpha (coefficients of gas transfer) are still the same as before. version 2021.04.03: includes globally integrated fluxes including all wind and pco2 products. version 2021.04.02: removed some files that remained from v2021.02 that I didn't delete in v2021.04 version 2021.04 now extends the variables to calculate fluxes from 1982-2020. The comparison period for fluxes is now limited to 1990-2019 (30 years). The area contains coastal fraction coverage. A missing strip along the longitude 179.5°E is filled in. Negative values of pCO2 are limited to 50 µatm (primarily affects JENA in Hudson Bay). version ... |
