The atmospheric component of MIROC5 used in this study has T42 (about 300 km grid) horizontal resolution, whereas the original version of MIROC5 has T85 (about 150 km grid) resolution, with 40 vertical levels.
However, while the horizontal resolution of 2.5 ° (T42) or better in
the atmospheric component of many coupled models is probably adequate to resolve most important features, the typical vertical resolution of around 20 levels is probably too low, particularly in the atmospheric boundary layer and near the tropopause.
