In the first phase of the nextGEMS project, the two Earth-system models ICON and IFS were developed in three iterative cycles aiming at simulating the climate 30 years into the future at storm-resolving scale. Each cycle was concluded by a Hackathon evaluating results and evolving effective workflows for these scales. The resulting model versions of ICON (2.6.6-2024.01-e00c44646b - nextgems_prefinal-ngc4008) and IFS (48R1 base version + 49R1 land developments + nextGEMS developments) + FESOM tag 2.5.0.3_de are now used in a production phase to simulate climate projections for 2020-2049, and to publish the corresponding datasets in a way amenable to the workflows that have emerged out of experience from the phase 1 Hackathons.
The catalog is freely available, for access to the data itself a DKRZ account is required.
