Extended Data Figure 4: Flux uncertainty statistics.
From: Drought sensitivity of Amazonian carbon balance revealed by atmospheric measurements
a, Sensitivity of flux estimates to profile extrapolation height (months and years are abbreviated below). Comparison of quarterly flux estimates calculated by mass balance of air column up to the top level of measurements (4.4 km a.s.l.), up to 10 km and 8 km a.s.l. during the dry and 12 km during the wet season. b, Distributions of annual net carbon flux estimates obtained with Monte Carlo uncertainty propagation (described above) and 68 and 95 percentile intervals of the mean.
