| Zusammenfassung |
| In light of climate change, the recording of extreme events is becoming an increasingly
important element of climate research. Of major importance is the recording of temperature
extremes with high spatial resolution.
Synoptical weather stations around the world measure daily extreme temperatures. However,
being point measurements they must be regionalised by means of an appropriate interpolation
algorithm that considers topographical features and daily weather conditions.
Previous works have used various interpolation techniques to generate high-resolution
gridded datasets of daily climate variables for Europe. For example, within the E-OBS project
(Haylock et al., 2008), which produced high-resolution (25 km²) daily maps of temperature and
precipitation, Kriging with external drift was chosen as interpolation algorithm.
The aim of this study is to generate a map of daily 2 m temperature extremes covering the
WMO Region VI (Europe and the Middle East) with a spatial resolution of 1 km² by means of
regression-Kriging combined with a digital elevation model. The quality of the algorithm is
evaluated using cross validation.
