Fig. 14

Cumulative distribution of modeled (squares) versus measured (circles) rates of change in live aboveground carbon. Each point on the curve represents the mean within an ecological section (A) or subregion (B). Points are colored according to the ranking of the FIA data from most negative to most positive rate of change, such that if regions’ rates of change were ranked exactly the same in each dataset the color pattern would be the same for both curves. The largest positive rates of change are shown in pink for both curves, showing that both datasets agree as to the group of subregions with the fastest increases in carbon mass over time, but the color mismatch at the left end of each curve shows that those subregions that the FIA data shows to be losing the most live carbon are not captured by the model
