 Activities in this group mainly contribute to the development and usage of weather and climate models such as ICON or COSMO for modern technologies (*e.g.* beyond CPU architectures).
 
 ### WG 2 - Weather and Climate Modelling
-This group gathers all activities revolving around weather and climate modelling at the exclusion of WG1 (HPC), like usage, maintenance and support. They can target weather and climate models and their potential extensions (*e.g.* aerosols, chemistry) and ESMs. Tasks may include coupling of model components, general tools around pre- and post-processing, automated testing, etc.
