ICON is a modeling framework for weather, climate, and environmental prediction. It 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. More information about ICON is available at https://www.icon-model.org/. The ICON Code is documented in GitLab: https://gitlab.dkrz.de/icon/icon-model.
