2. ECMWF/IFS was used for recent Campaign analyses
Rationale
ECMWF/IFS was used for recent Campaign analyses
Need to find a consistent meteorological driver
=> Hindcasts of CORDEX Regional Climate Downscaling

3. EURO-CORDEX
Hindcast with perfect boundary conditions to assess regional climate models
Driven by ERA-Interim, no nudging
Thoroughly documented in Kotlarski et al., GMD 2014
Cover , often extended to 2012
Ensemble:
9 models at 0.11 deg
8 additional models at 0.44 deg.
