Short summary
We present an implementation of the Discontinuous Galerkin approach, a numerical solver of the Euler equations (called BRIDGE (Basic Research for ICON with DG Extension)), which is in particular well suited for numerical models for weather and climate prediction and atmospheric research. Two widespread formulations of the Euler equations with different thermodynamic variables are compared by the inspection of idealised benchmark test cases to assess the properties of the Discontinuous Galerkin method.
