Short summary
We present an upper-atmosphere extension of the ICOsahedral Non-hydrostatic (ICON) model. This includes an extension of the model dynamics from a shallow to a deep atmosphere and the implementation of upper-atmosphere physics parameterizations. Idealized test cases and climate simulations are performed in order to evaluate this new configuration, named UA-ICON.
