Model Output Assessing Net Carbon Exchange Across the Arctic Tundra-Boreal Forest Transition in Alaska, 1981-2000


In this study, investigators simulated the temporal and spatial patterns of net carbon exchange in Alaskan ecosystems that span the transition from Arctic tundra to boreal forest. They modeled net carbon storage in terrestrial ecosystems by the balance between net primary production (NPP) and decomposition. They also modeled vegetation and soil carbon and nitrogen pools in tundra, shrub tundra, and tree line evergreen conifer forest ecosystems. Field data were used to develop parameterizations for the Terrestrial Ecosystem Model (TEM) 5.0. Investigators extrapolated the model spatially over the Alaskan Arctic to boreal tree line to simulate changes in vegetation and soil carbon storage from 1981-2000 (Thompson et al. 2005). Data are in Microsoft Excel Comma Separated Values format.
