With respect to the simulated trend in annual mean daily maximum or minimum temperature,
none of the methods substantially alter the model simulated trend (e.g. Figure 9).
In fact, dynamical downscaling appears to modify the model trend much more than bias correction.

### 5.9. Precipitation trends

> Summary: Bias correction slightly modifies model simulated precipitation trends.
> These modifications are smaller than those produced by dynamical downscaling
> and tend to be slighly larger for multivariate bias correction.
With respect to the simulated trend in annual mean rainfall,
the univariate and multivariate methods slightly alter the model simulated trend (e.g. Figure 6.5.1 and 6.5.2).
Dynamical downscaling appears to modify the model trend much more than bias correction.
Bias correction tended to slightly alter the model simulated rainfall trends (e.g. Figure).
The grid point differences in percentage change in annual mean precipitation between 1980-2019 and 2060-2099
beween the raw RCM data and the ECDFm, QME, MBCn and MRNBC data had a mean absolute error across all RCM/GCM cominations
of 3.4%, 2.4%, 9.5% and 4.2%, respectively.a
For all RCM/GCM combinations, dynamical downscaling modified the model trend more than bias correction.
