ICCARUS 2024 **special WG "ICON-based Earth System Modelling"**

The ICCARUS (ICON/COSMO/CLM/ART USER Seminar) 2024 will take place as a hybrid seminar from 04 to 07 March, 2024 with an online Postersession on 11 March. The first three days, from 04 to 06 March, are dedicated to plenary sessions. Plenary sessions can be attended online or in-person. This is followed by in person or hybrid working group meetings on Thursday 07 March. The online poster session will take place on Monday 11 March.

ICCARUS brings together developers and users of the non-hydrostatic COSMO and ICON models, which are used in numerical weather prediction as well as for climate simulations and modeling of air quality and its feedback to the atmosphere.
The Seminar is a forum for COSMO- and ICON groups to exchange information about model development, physics parameterizations, data assimilation, ensemble generation, verification and applications.

**Special**
There will be a group meeting on "ICON-based Earth System Modelling" online on Wednesday 13 March 9:00 a.m. - 3 p.m., with 3 sub-sessions planned:

• regional earth system modelling (ICON-O-LAM and zoom, including coastal refinement; regional climate projections)
• data assimilation (coupled, ocean, land, ... DA at all scales)
• physics & tuning (hydrology, sea-ice, frozen soil, waves, carbon cycle, ...)

Organized by Martin Köhler, Nora Schenk and Vera Maurer (all DWD)
