Icon usually runs at 13k..
In the current operational version, the global ICON grid has 2,949,120 triangles, corresponding to an average area of 173 km² and thus to an effective mesh size of about 13 km.
It has a his rez version in germany..
While large mountain ranges can be represented reasonably well at a mesh size of 13 km, capturing individual mountain ranges or valleys requires even finer meshes. However, resolving such features can be important for some aspects, e.g. predicting the channeling of the low-level airflow in the Rhine Valley. Therefore, DWD operates in addition the high-resolution limited-area model COSMO-DE with a mesh size of 2.8 km.
