.. _ICON-DYAMOND-SUMMER: ICON ======================================== Model description ----------------- ICON is a non-hydrostatic model discretised over an icosahedral as described by `Zängl et al. (2015) `__.  Here it is run in a global configuration using a set up similar to that described by `Klocke et al. (2017) `__. Contact ~~~~~~~ `Luis Kornblueh `__, Max Planck Institute for Meteorology (MPI-MET), DE Data structure -------------- Vertical ~~~~~~~~ The number of vertical levels is chosen as 90. A detailed description of the placement of the vertical levels can be downloaded `here `__. Horizontal ~~~~~~~~~~ ICON employs horizontal grid spacing of 5km (R2B9) and 2.5km (R2B10), comprising 20 971 520 (5km)/ 83 886 080 (2.5km) grid columns.
