The ORNL DAAC announces the release of two data sets from Phase 2 of the Vegetation/Ecosystem Modeling and Analysis Project (VEMAP).
The two data sets contain monthly and annual results, respectively, from experiments conducted to compare the ecological responses of the suite of VEMAP models to projected transient scenarios of climate and atmospheric carbon dioxide for the period 1994 to 2100. The models investigated included five biogeochemical cycling models, which simulate plant production and nutrient cycles but rely on a static land-cover type, and two dynamic global vegetation models (DGVMs), which combine biogeochemical cycling processes with dynamic biogeographical processes including succession and fire simulation.
VEMAP was an international project studying the response of biogeochemical models and vegetation-type distribution models (i.e., biogeographical models) to variability in climate and to other spatial and temporal factors. Phase 1 compared the results of six models under various climate and vegetation scenarios. Phase 2 compared time-dependent ecological responses of models to historical and projected transient scenarios of climate and atmospheric carbon dioxide.
