ALT The figure on top shows the land cover type and land change processes considered in the study. The processes of wildfire, tree partial cut, and crop harvest are also included. The bottom figure shows the major ecosystem carbon pools.

ALT This figure shows the ecosystem carbon stocks and fluxes of the conterminous U.S. from 1985 to 2020. (1) Values in the flowchart represent the 1985–2020 annual mean carbon stock or flux with uncertainty ranges (units in Tg C and Tg C/yr). The carbon stock of inland waters is unknown but assumed to be constant. NPP: net primary productivity; NBP: net biome productivity; DIC: dissolved inorganic carbon; DOC: dissolved organic carbon; POC: particulate organic carbon. (2) The inset graph shows the temporal trends of CONUS-scale terrestrial NBP, with uncertainty range (1.96 x STDEV) based on Monte Carlo simulations. A positive value indicates net carbon gain, while negative value indicates net carbon loss.
