This study presents detailed sensitivity experiments analyzing air-sea CO2 fluxes through various parameters. Conducted are 11 sensitivity tests, including 5 with differing initial conditions, variations in air-sea gas exchange velocity, vertical tracer diffusion, POC to PIC ratio adjustments, and dissolution rate changes of PIC. Additionally, Green's function runs utilize global mean air-sea CO2 fluxes and seasonal pCO2 variability from Takahashi. The simulated CO2 fluxes are derived from linear combinations of these experiments, providing insights into global carbon dynamics.
