The following plots show Taylor diagrams for the bias-corrected and the raw RCM simulations at the EURO-CORDEX 0.44° grid (click for hi-res images). The daily 0.44° EOBS10 data are used as reference. Correlations and standard deviations are calculated from spatial values, i.e., the long-term means (1981-2010).

The RCM runs shown are given in the legend. Each plot shows the bias-corrected (large symbols) and the raw data (smaller symbols) for one variable (in the order pr, tas, tasmax and tasmin) and for the four seasons winter (DJF), spring (MAM), summer (JJA) and fall (SON).

Annual and seasonal biases of the raw and bias-corrected for the individual RCM runs are shown here:

bias_tas_eur-44.pdf

bias_tasmin_eur-44.pdf

As expected, the bias-correction method reduces (but does not remove) the seasonal biases and removes the annual biases (almost) completely for all variables.
