a Map of aboveground live woody biomass carbon density (Mg C ha−1) and b uncertainty across forest lands of the conterminous US at 1-ha resolution for circa the year 2005. c The regional analysis was performed by dividing the US into three sub-regions as recommended by Heath and Birdsey [19]. The above and belowground carbon density maps and the uncertainty maps can be downloaded from NASA’s distributed Data Active Archive Center (http://dx.doi.org/10.3334/ORNLDAAC/1313)
