//////////////////////////////////////////////////

Location (now on Levante):
    :file:`/work/ka1081/NextGEMS/MPIM-DWD-DKRZ/ICON-SAP-5km/Cycle1/`

Setup:
    Coupled atmosphere and ocean (ICON-O) and land model JSBACH

Simulated period:
   20 Jan 2020 00:00 - 1 Mar 2021 00:00

Resolution:
    * horizontal grid spacing of 5km (R02B09) for ocean and atmosphere, comprising 20971520 grid columns and 14886338 grid columns for the ocean
    * number of vertical levels for the atmosphere: 90 terrain following layers (#1 at top, 90 boNom), top at 75km, lowest at 25m
    * number of vertical levels for the ocean: 128

Comments:
    * resolved atmospheric physical processes: shallow and deep convection, sub-grid scale orography, gravity wave drag
    * parameterised processes: all-or-nothing scheme for the cloud cover, 1-Moment micro-physics with graupel, 3d Smagorinsky turbulence scheme, psRad radiation scheme
    * ocean spin-up run initialised with ORAS5 (30km), spun-up with ERA5 forcing (10 years at 10km and 5 years at 5km)
    * new vertical coordinate z* in the ocean: variable coordinate system, which allows thin layers (here 2m at top) and thick sea-ice
    * atmosphere time step set to 40 sec, ocean time step set to 120 sec
