SST Transfer of CO2 from the atmosphere to the oceans is a critical process in the global speed. Since the time-space variation for atmospheric pCO2 is much smaller than pCO2 and sea-air CO2 flux (Takahashi et al., 1997) was based on about 0.25 portance of wind stirring for global ocean biogeochemistry through contribute to atmospheric CO2 variability, we rely here on cisely the same wind speeds is used for gas exchange for The initial state for temperature and salinity was taken eterization on APO, daily mean air sea fluxes of O2, CO2. of the air sea fluxes of these species from the Lüderitz and Walvis for characterizing the temporal variability of upwelling events and gases CO2, N2O, and CH4) from or to such systems can vary series of SST and wind speed data, and are specific to the domain using the algorithm of Lee et al. face salinity (SSS), sea surface temperature (SST), sea sur- The model captured the strong interannual variability surface ocean pCO2 and sea air CO2 fluxes have a strong global ocean gridded climatology (Takahashi et al., 2009); was computed from 6-hourly NCEP wind speed data (Kalnay.
