Apart from its innovative triangular grid, ICON has several advantages over existing models; in particular the combination of a non-hydrostatic core with the option of heterogeneous forcing and non-periodic boundaries creates ideal opportunities for research of scale-adaptive parameterizations. The setup allows to simulate various synoptic situations at different places and a reasonable comparison to observational data - with this the testbed-situations for parameterization development is growing and getting more variable. | Apart from its innovative triangular grid, ICON has several advantages over existing models; in particular the combination of a non-hydrostatic core with the option of heterogeneous forcing and non-periodic boundaries creates ideal opportunities for research of scale-adaptive parameterizations.

The LES infrastructure lends itself perfectly for SCM on microgrids, as i) it already has a fully non-hydrostatic dynamical core, and ii) it can easily be run on small grids. An additional advantage in this respect is that the LES is a lot simpler in its setup compared to a GCM, which can enhance the transparency of any numerical experiments, | The LES infrastructure lends itself perfectly for SCM on microgrids, as i) it already has a fully non-hydrostatic dynamical core, and ii) it can easily be run on small grids.
