### 5.1. Temperature climatology

While RCM output was generally associated with smaller biases
in the temperature annual climatology and seasonal cycle than corresponding GCM output,
some bias still persisted and tended to have its own unique spatial characteristics
(i.e. different from the GCM; e.g. Figure 3).
When bias correction was applied to RCM output
following the calibration assessment task protocol
(i.e. with an overlapping training and correction period),
those biases were typically almost completely eliminated.

Biases in the RCM output were also greatly reduced

The MBCn method was again the worst performing on cross validation,

The residual bias after applying the ECDFm and QDC methods

whether GCM data are dynamically downscaled or not prior to applying bias correction.
