Adjustment factors used to amend live-tree belowground C estimates from the current US national greenhouse gas inventory (BGCNGHGI; Smith et al. [13]) with climate-derived predictions (BGCClim; Reich et al. [8]) by US region and forest type. Adjustment factors less than and greater than one indicate less and more belowground C when climate-derived predictions are used. See Additional file 1: Table S1 for mean belowground C values and adjustment factors
