Short summary

This study uses a global oceanic model to investigate the seasonal dynamics of the sea surface partial pressure of CO₂ (pCO₂) in the global coastal ocean. Our method quantifies the respective effects of thermal changes, biological activity, ocean circulation and freshwater fluxes on the temporal pCO₂ variations. The performance of our model is also evaluated against a data product derived from observations to identify coastal regions where our approach is most robust.
