SFLUX : Standard deviation of diagnostic flux

WEIGHT : Number of data time steps used for the statistics


2) Excel file containing the monthly means of the global ocean CO2 sink (PgC/y) corresponding to all the different diagnostics previously described (Parc et al. 2024) : GlobalOceanSink_2008-2018_rain_monthly_diagnostics.xlsx
