Global air-sea CO2 exchange flux since 1980s: results from CMIP6 Earth System Models
The ocean could profoundly modulate the ever-increasing atmospheric CO2 by air-sea CO2 exchange process, which is also able to cause significant changes of physical and biogeochemical properties in return. In this study, we assessed the long-term average and spatial-temporal variability of global ai...
