Short summary

To understand South Korea's CO₂ emissions and sinks as well as those of the surrounding region, we used flask-air samples collected for 2 years at Anmyeondo (36.53° N, 126.32° E; 46 m a.s.l.), South Korea, for analysis of observed ¹⁴C in atmospheric CO₂ as a tracer of fossil fuel CO₂ contribution (C_ff). Here, we showed our observation result of ¹⁴C and C_ff. SF₆ and CO can be good proxies of C_ff in this study, and the ratio of CO to C_ff was compared to a bottom-up inventory.
