ICON-Seamless describes the joint activity of the German Weather Service (DWD), the Max Planck Institute for Meteorology (MPI-M) and the Karlsruhe Institute of Technology (KIT) to develop an Earth system model for weather and climate forecasts, which is based on the components of the numerical weather prediction model (ICON-NWP), the land model (JSBACH), the ocean-sea ice model (ICON-O) and the aerosol and reactive trace gas model (ICON-ART). In addition, climate projections (including the relevant material cycles) and high-resolution climate simulations are also made possible with this ICON configuration. The climate configuration of ICON is labelled ICON-XPP.
ICON-XPP will be able to simulate the material cycles between land, atmosphere and ocean required for weather and climate simulations as well as the aerosol concentrations required for air quality simulations. The various model configurations of weather and climate forecasts, climate projections as well as chemistry and transport simulations will be controllable via Namelist configurations.
The software ICON in general is now open source under BSD-3C license.The current ICON configuration for weather and climate forecasts can be found here.

If you want to get started, you have to get in touch with the developers. The ICON Seamless community holds regular online meetings to keep each other up to date and discuss initial results. Have a look in our event section for updates.
