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).

Experiment runs#

Warning

For the grib files, cdo needs the correct grib definition path to get the variable names straight. On Levante use:

GRIB_DEFINITION_PATH=/sw/rhel6-x64/eccodes/definitions cdo [arguments]

or:

export GRIB_DEFINITION_PATH=/sw/rhel6-x64/eccodes/definitions
cdo [arguments]

ICON-NWP 2.5km atmosphere-only#

Location:

/fastdata/ka1081/DYAMOND/data/winter_data/MPIM-DWD-DKRZ/ICON-NWP-2km/DW-ATM/

containing grid information in atmos/grid/ and atmos/fx/

Setup:

Atmosphere-only, with land module Terra

Resolution:

  • horizontal grid spacing of 2.5km (R02B10), comprising 83886080 grid columns

  • number of vertical levels for the atmosphere: 90

Comments:

  • As the ICON 2.5km simulation for DYAMOND-Summer (see Stevens et al. 2019)

  • Important: The 00:00:00 time slices are missing. To our knowledge, that was a problem in the 2.5 km NWP setup of ICON used for this simulation.
