Short summary

This paper introduces REMO2020, a modernised version of the well-known and widely used REMO regional climate model. We demonstrate why REMO2020 will be our new model version for future dynamical downscaling activities. REMO2020 outperforms the previous REMO version in almost all areas used to evaluate the European climate. It also supports climate service need-based developments through a new, more modular structure.
