SUMMARY:Starting Open Development with the ICON Model: Conditions, Conflic
 ts and Challenges
DESCRIPTION:Ralf Müller (German Climate Computing Centre)\n\nICON, a weath
 er and climate model originally developed by the German Weather Service an
 d the Max Planck Institute for Meteorology in 2004, has since expanded wit
 h additional institutional partners. Since 2024, ICON is distributed under
  an open-source license, yet it lacks a fully open development workflow fo
 r the public. Divergent needs for scientific workflows and production runs
  across institutions create tensions between open development and stable p
 roduction environments. Overcoming hierarchical and institutional barriers
  is essential to demonstrate the benefits of an open workflow while preser
 ving room for private features. In response, common requirements were iden
 tified and leveraged to improve documentation for a unified development wo
 rkflow, standardized configurations, and a modern platform for communicati
 on between developers and users. This talk outlines ICON’s current status,
  the steps taken to achieve it, transferable patterns for groups facing si
 milar challenges, and how ICON’s approach compares with commercial softwar
 e development.\n\nDomain: Climate, Weather, and Earth Sciences, Applied So
