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.
