Soil residual water corresponds to the model variable "total
streamflow"." In the model MC1, this is calculated (in
cm of water) as the water flowing through the soil profile below the
last soil layer (streamflow), water leached into the subsoil (baseflow)
and also includes runoff. The output is presented here as a monthly
average. Soil residual water is part of the model output from Brendan
Rogers' MS thesis work. Brendan used the vegetation model MC1 to
simulate vegetation dynamics, associated carbon and nitrogen cycle,
water budget and wild fire impacts across the western 2/3 of the states
of Oregon and Washington using climate input data from the PRISM group
(Chris Daly, OSU) at a 30arc second (800m) spatial grain. The model was
run from 1895 to 2100 assuming that nitrogen demand from the plants was
always met so that the nitrogen concentrations in various plant parts
never dropped below their minimum reported values. A CO2 enhancement
effect increased productivity and water use efficiency as the
atmospheric CO2 concentration increased. Future climate change scenarios
were generated through statistical downscaling from general circulation
model output using anomalies and a climatology from the PRISM group at
30arc second spatial grain. Data came from three General Circulation
Models (CSIRO Mk3, MIROC 3.2 medres, and Hadley CM 3), each run through
three CO2 emission scenarios (SRES mild B1, moderate A1B, and warm and
dry A2).
