century, the north-south difference of Δ14C- CO2 was counterintuitively positive, with higher Δ 14C-CO2 being observed in the North than in the South (Levin and Hesshaimer 2000). This latter north-south difference [...] the sign in the north-south Δ 14C-CO2 difference has been previously reported by Graven et al. (2012). There are two reasons that may have caused this reversal: (1) The increase of the north-south gradient [...] flux is largest, also because large wind velocities enhance air-sea gas exchange. As is the case for the long-term trend, changes in the north-southΔ 14C-CO2 difference can also provide a constraint on the
