Target configuration for coupled systems (ICON-ESM, ECMWF, EC-Earth, IPSL-CM) (MS1.1)

ESiWACE2 will push resolution towards unprecedented levels for coupled simulations in production mode that show a performance that would allow operational weather and climate predictions (at least 1 SYPD) with realistic model output with a resolution that is as high as possible. Four coupled models have been chosen for this exercise. The model configurations that are developed within WP1 of ESiWACE2 will be ported to the European pre-exascale EuroHPC systems planned for 2021. The scaling behaviour of the models will be diagnosed and documented. To achieve this goal towards Deliverable D1.1 and D1.3, this Milestone is specifying the model configurations that will be used for the four models that will be run in production mode. Three of the models are aiming for the model output requirements of the 2nd phase of the DYAMOND intercomparison to define a realistic model output for production simulations. https://www.esiwace.eu/services/dyamond/dyamond-2nd-phase-the-winter-experimental-protocol/vie
