Estimates the uncertainty in carbon accumulation potential from natural forest regrowth. Specifically, the uncertainty metric is calculated as the modeled sequestration rate (mean of 100 random forest models) divided by the standard error of the 100 random forest models. Uncertainty is presented as a ratio because areas with higher sequestration rates tend to have high standard errors for their sequestration rates; presenting error as a ratio standardizes the model error by the sequestration rate. Higher numbers represent greater uncertainty in the model. For reference, an error ratio of 0.5 means that the standard error of the random forest models is half as large as the mean output of the models for that pixel. The rate uncertainties were estimated over all forest and savanna biomes.Extent: Global, within forest and savanna biomesCitation: Cook-Patton, S.C., Leavitt, S.M., Gibbs, D. et al.
