ICON-ART (ICOsahedral Nonhydrostatic weather- and climate model with Aerosols and Reactive Trace gases)

ICON-ART is a state-of-the-science seamless model system for the whole atmosphere (physics and composition) that comprises the key components of the next generation Earth system model in Germany. ICON is a global weather and climate model solves the full three-dimensional non-hydrostatic and compressible Navier-Stokes equations on an icosahedral grid and allows seamless predictions from local to global scales. Aerosol and Reactive Trace gases (ART), as a submodule of ICON, supplements the model by including emissions, transport, gas phase chemistry, and aerosol dynamics in the troposphere and stratosphere.

German Weatherservice (DWD) uses ICON-ART for operational forecasts of mineral dust and pollen. It is also used by MeteoSwiss for pollen forecasts.

Training course for the model system ICON-ART

Training courses on the ICON-ART model system are held annually. They are organized in collaboration with the Institute for Meteorology and Climate Research (IMK) of the Karlsruhe Institute of Technology (KIT) and the German Weather Service (DWD). The next ICON training course will take place in March 2023. For upcoming events, please refer to the DWD website.

ICON-ART Training Background

The ICON-ART training took place on 11-12.05.2023 online. The course includes lectures on theoretical/technical backgrounds and hands-on experiments on HPC systems. The next training course will take place in 2024.
