Short summary

This study focuses on exploring the differences in calculating global surface CO₂ and its growth rate, considering the impact of analysis methodologies and site selection. Our study reveals that the current global CO₂ network has a good capacity to represent global surface CO₂ and its growth rate, as well as trends in atmospheric CO₂ mass changes. However, small differences exist in different analyses due to the impact of methodology and site selection.
