The joint development by DWD and MPI-M of the new nonhydrostatic weather and climate modelling framework ICON has made considerable progress in recent years. At DWD ICON (13 km grid spacing, 90 layers) has already replaced the former NWP model GME (20 km grid spacing, 60 layers). The higher resolution European nest (6.5 km grid spacing) in ICON is also already operational and has replaced the regional model COSMO-EU (7km grid spacing, 40 layers). The ICON software and documentation is available to the scientific community (license aggrement necessary). For the next few years, COSMO will still be used in very high-resolution regional applications (COSMO-DE, COSMO-DE-EPS), but until 2020 the whole COSMO system is planned to be replaced entirely by the ICON modelling framework in cooperation with the COSMO Consortium and KIT (for the ART application). It is important for the CLM community to be prepared for a migration to the ICON modelling framework.


The aim is to make the first steps with the ICON software soon after the release to the scientific community. The main objectives of this project group are to:

  • inform the community about the timelines and progress of the ICON development
  • prepare a working plan (plan of action) including an overview of the work packages necessary for using the ICON modelling framework in the context of regional climate studies and to organize its implementation,
  • design and conduct test suites of the new regional mode of the ICON model in comparison to COSMO-CLM model results,
  • and to present the results to the CLM Community.
