Fig. 3: Attribution of the land carbon fluxes in the Brazilian Amazon over 2010-2020 from bottom-up models.
From: Synthesis of the land carbon fluxes of the Amazon region between 2010 and 2020
a Annual net disturbance fluxes from the disturbance multi-model average (see Tables 2–3 in Methods section); shaded grey area represents the 1 SD of the multi-model average; individual uncertainty is not available for each model. b Annual old-growth land sink from TRENDY-v11 S2 simulations; shaded green area represents the 1 SD of the TRENDY-v11 DGVMs mean and shaded orange areas represent the ENSO years, which cause stronger drought events in the Amazon and consequent water stress and therefore a reduction in the old-growth sink (R = −0.88, p < 0.001; see Supplementary Figure 2b for a correlation between the old-growth sink annual variation and a drought index). c Multi-model mean annual disturbance flux (gC m−2 yr−1). d Multi-model mean annual old-growth land sink from TRENDY-v11 S2 simulation (gC m−2 yr−1). The spatial uncertainty of (c) and (d) can be found in Supplementary Fig. 7. Positive values (pink) indicate a net carbon source to the atmosphere and negative values (green) indicate a net sink.
