nextGEMS: output of the model development cycle 2 simulations for ICON and IFS

Summary In the first phase of the nextGEMS project, the two Earth-system models ICON (Version ee0ee6) and IFS (Cycle 47r3.3 nextGEMS) are developed in three iterative cycles aiming at simulating the climate 30 years into the future at storm-resolving scale. In each development cycle new features are implemented into the models improving the physical representation of the coupled Earth system as well as the technical feasibility to run at high resolution for increasing simulation time periods. A development cycle concludes with a simulation for at least one year at 5 km horizontal resolution or lower. The cycle 2 model runs produced about 1 PB of model output. A subset of the data is published here, namely monthly averages of selected 2d variables from the 5km ICON simulation and 4km IFS simulation.   Below follows general information on the ICON and IFS-FESOM model outputs. The datasets of both can be retrieved from the download section of this contribution. ------------------------------------------------------------- ICON model output (nextGEMS cycle 2) Within the nextGEMS project the ICON model was run at 5km horizontal resolution for about 2 years. Details on the model configuration and it's previous development within the project can be found at https://easy.gems.dkrz.de/DYAMOND/NextGEMS/index.html#id1. The present dataset includes selected 2d variables and is a subset of the full model output which is available on request. Here, we publish the 2m temperature, wind speed at 10m height, precipitation, sea surface temperature, the mixed layer depth, latent and sensible heat fluxes, net short-wave radiation at top of atmosphere, and the outgoing longwave radiation.
