Terrestrial biosphere carbon cycle process

@The vegetation absorbs carbon dioxide (CO2) from the atmosphere by the net primary production (NPP, gross primary production minus respiration). NPP is estimated from temperature, precipitation, and atmospheric CO2 concentration by the observational empirical formulation; NPP generally increases along with the increase in those three factors.
@The carbon absorbed from the atmosphere to the vegetation is distributed to the parts of vegetation (leaf, branch, stem, and root), then transferred into litter, humus, and charcoal according to the turnover times estimated by the observations, and finally emitted to the atmosphere by the soil respiration.
