The *next Generation Earth Modeling Systems* is a Horizon 2020 European Union funded project lead by the [Max Planck Institute for Meteorology](https://mpimet.mpg.de) and the [ECMWF](https://ecmwf.int) in which storm-resolving global models are further developed and compared in performance.

Two complementary Earth system models (ICON and IFS-FESOM) successfully performed 30-year simulations under the SSP3-7.0 climate scenario with approximately 10 km atmospheric resolution and 5 km ocean resolution.
