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

Aerosol and Reactive Trace gases (ART) is a component of the ICON modeling framework that enables explicit treatment of atmospheric composition and its interactions with clouds and radiation. ART encompasses emission, transport and removal processes of trace gases and aerosols in the troposphere and stratosphere along with their transformations due to chemistry and aerosol microphysics.

ICON-ART is a powerful tool used in various scientific domains including air quality modeling, tracer transport, weather forecasting and climate studies. German Weatherservice (DWD) uses ICON-ART for operational forecasts of mineral dust and pollen. It is also used by MeteoSwiss for pollen forecasts.

Release Download

For downloading the latest release of the code please visit ICON website. The current release is tested and thus supports the following configurations. Any other configuration and combination of processes is not fully tested and thus, currently cannot be supported. The input data for these configurations are here

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 June 2024. For upcoming events, please refer to the DWD website.

The ICON-ART training will also take place in June 2024 online. The exact dates and schedule will be announced here. The course includes lectures on theoretical/technical backgrounds and hands-on experiments on HPC systems.
