| Zusammenfassung |
| A Hearter bias correction is performed on 2081 to 2100 temperature and
precipitation fields from three different GCMs and two different
scenarios. For each GCM, four non-overlapping consecutive decadal
calibration periods of past climate are used to derive 4 different sets
of bias correction parameters. The result is a 24 member ensemble of 20
year simulations. These are used to force the MPI land-surface model from
which we extract a 15 year time series of discharge for 5 large catchment
areas. The spread in statistical moments of discharge values is analyzed.
Spread deriving from the choice of decadal period used to drive the bias
correction parameters is compared with the spread deriving from choice of
GCM and scenario. |
