| Zusammenfassung |
| This paper discusses the relative performance of several climate
models in providing reliable forcing for hydrological modeling in
six representative catchments in the Mediterranean region. We
consider 14 Regional Climate Models (RCMs), from the EU-FP6
ENSEMBLES project, run for the A1B emission scenario on a common
0.22° (about 24 km) rotated grid over Europe and the
Mediterranean region. In the validation period (1951 to 2010) we consider
daily precipitation and surface temperatures from the observed data fields (E-OBS) data set,
available from the ENSEMBLES project and the data providers in the
ECA&D project. Our primary objective is to rank the 14 RCMs for
each catchment and select the four best-performing ones to use as
common forcing for hydrological models in the six Mediterranean
basins considered in the EU-FP7 CLIMB project. Using a common suite
of four RCMs for all studied catchments reduces the (epistemic)
uncertainty when evaluating trends and climate change impacts in the
21st century. We present and discuss the validation setting, as well
as the obtained results and, in some detail, the difficulties we
experienced when processing the data. In doing so we also provide
useful information and advice for researchers not
directly involved in climate modeling, but interested in the use of
climate model outputs for hydrological modeling and, more
generally, climate change impact studies in the Mediterranean region. |
