Warm World

To better assess the impact of a warmer world, coupled climate models such as ICON must be capable of global simulations at the km scale. The move to higher resolution and thus more grid points is accompanied by a significant increase in the resources required. In the compute as well as in the data analysis area, adapted methods on HPC systems will be necessary to enable global, storm-resolving simulations.

DKRZ is leading or participating in two subgroups of the overall WarmWorld project: i/ WarmWorld-Faster to adapt the ICON code to upcoming heterogeneous exascale HPC systems and ii/ WarmWorld-Easier to create a data analysis system for high-resolution ICON simulations based on ECMWF's FDB5 system and in-situ analyses.
