The community of Earth system modelling has a strong interest to reach a horizontal resolution of about 1km for ensemble simulations with global coupled weather and climate models. Within the ESiWACE project, we have demonstrated that 1 km simulations with global atmosphere models are technically feasible (see ESiWACE Deliverable D2.1). However, we are still far from being able to run a 1 km coupled ensemble in an operational mode even if some of the fastest supercomputers that are currently

This deliverable presents a concise roadmap that lays out the technical work, and the financial and organisational framework that is needed to run ensembles of Earth system models (ESM) at 1km resolution with enough throughput to perform operational weather forecasts and climate projections.
