Fig. 2: Contribution of three latitudinal bands to the relationships between global interannual variability of net ecosystem exchange (NEE_IAV) and terrestrial water storage (r_TWS) or temperature (r_T).

In panel a, positive values mean that the NEE_IAV in the latitudinal band supports the dominance of terrestrial water storage in the global NEE_IAV while the negative values mean that the NEE_IAV in the latitudinal band supports the dominance of temperature. In panel b, the solid bars are the contributions to the global r_TWS (C^TWS) while open bars are the contributions to the global r_T (C^T). Positive values of C^TWS or C^T mean that removing the regional NEE_IAV would reduce the absolute value of the global r_TWS or r_T. In panels a and b, green bars indicate NEE_IAV is estimated by atmospheric inversions, while blue bars and brown bars indicate that NEE_IAV is estimated by DGVMs from the TRENDY project in simulation S2 (NEE output) and by FLUXCOM models, respectively. For atmospheric inversions and FLUXCOM models, the error bars indicate the range of models while for DGVMs from the TRENDY project, the error bars indicate the 1-σ inter-model spread.
