  1. The table presents the sensitivity of the emergent constraint on ΔCs,τ to model ensemble: CMIP5, CMIP6 or CMIP5 and CMIP6 combined (columns), and to the observational dataset for heterotrophic respiration (rows). The penultimate row presents the constraint using the observational τs v T fit and model Rh,0, opposed to observational Rh,0, to isolate the uncertainty reduction from these different components. For comparison, the last row shows the mean and standard deviation of the unconstrained model ensemble.
