From: A cautionary tale about using the apparent carbon accumulation rate (aCAR) obtained from peat cores
The effect of climate perturbations on simulated aCAR and NCB (20 year moving average). (a) Increase in temperature of 1.5 °C, (b) reduction in annual net rainfall of 0.4 m, and (c) both perturbations combined. The light grey vertical bars indicate the timing and duration of the perturbations and the dark grey dashed line is where C accumulation equals zero. The increases in NCB near to the beginning and end of the net rainfall perturbation (a and b) are due to the peatland water tables falling and later rising into the zone of maximum litter addition in DigiBog’s litter production equation.
