Predicting Generalized Ecosystem Groups with the NCAR CCM: First Steps towards an Interactive Biosphere

摘要: Abstract Canopy-plus-soil “big-leaf” models of the land surface now exist and are being incorporated in global climate models. These big-leaf could be basis for incorporation an interactive biosphere into However, their use depends upon satisfactory specification distribution plants (and soils), while such distributions can obtained present-day, they must manufactured all other climatic scenarios. Thus, one prerequisite is successful prediction natural vegetation (or “climax” vegetation) scenarios as doubling atmospheric carbon dioxide. (It also necessary to predict agricultural land-use classes, but that outside scope this paper.) A highly generalized (nine classes) grouping Holdridge life zones has been used here a means investigating three-step “coupling” land-surface scheme cl...
