Short summary
Understanding riverine carbon dynamics is critical for not only better estimates of various carbon fluxes but also evaluating their significance in the global carbon budget. In this study, we examined the dynamics of riverine CO2 partial pressure (pCO2) in the Yangtze River basin. Its pCO2 was characterized by strong spatial and temporal variations. With a basin-wide mean pCO2 of 2662(±1240) μatm, substantial CO2 evasion is expected. Future efforts are needed to evaluate its significance.
