Model Output from the Marine Biology Laboratory General Ecosystem Model (MBL-GEM) for Toolik Lake, 1921-2144, and the Kuparuk River Basin, 1995  View Catalog Page Entry ID
ARCSS052
Summary
This data set contains model input and output data for four simulations of varying time periods and spatial coverage.
The first two simulations are for acidic tussock tundra in the Toolik Lake region of the Kuparuk River watershed for the years 1921 to 2144. Each of these simulations is made up of two parts. The first part is based upon a reconstruction of historical climate variables from 1921 to 1995, while the second part is based upon a doubling of C02 and the concurrent changes in temperature, soil moisture, and irradiance from 1996 to 2144. The historical period is the same for both simulations. The future period differs between the two simulations: One simulation assumes a direct relationship between soil moisture and temperature (i.e., warmer and wetter), and the other assumes an inverse relationship between soil moisture and temperature (i.e., warmer and drier). The climate drivers used for the simulations are included as part of this dataset.
The second two simulations are for acidic tussock tundra throughout the entire Kuparuk River basin for 1995 only. The first simulation uses the reconstructed 1995 climate. The second simulation uses the same climate with an increase in soil moisture. The model output data consist of 34 variables including photosynthesis, plant and soil respiration, net primary production, net mineralization, and carbon and nitrogen stocks in plant tissues and soils.
