Figure 4 shows % contributions to global land carbon flux interannual variability over 2001-2023 from four atmospheric CO2 inverse model products. Note, the NISMON-CO2 map is depicted over a larger range due to higher contributions from tropical forests. While these products agree well with the global CGR from Fig 2, the regional agreements can be seen to be fairly poor, Petch et al. (2024).
