ClimEx is designed as a module based system and currently comprehends 3 modules:
An ensemble of 50 transient runs of the canadian general circulation model CanESM2 (~200km resolution) from 1950 to 2100, resulting in 7500 years of modelled climate. As each of these runs is initialized with only slightly altered starting conditions, this ensemble can be interpreted as (modelled) natural variability. The CanESM2 then drives the regional climate model CRCM5 (~11km resolution) for a domain that covers most of central Europe. Both models are internationally established and widely used in the climate science community.
The HYDROLOGY module focuses on modeling the major catchments in Bavaria and Southern Québec in high temporal and spatial resolution using physically based hydrological models. The climatic forcing by the data produced and collected in module CLIMATE allows us to make statements on natural variabilty and future changes for hydrological extreme events as well - with a focus on floods and high flows.
(FURTHER MODULES C, D, E, ... POSSIBLE)
In order to enhance efficiency for these analyses the third project component deals with the consolidation, coupling, and optimization of the two previous modules. Therefore, the LRZ provides its expertise in HPC and data management to consolidate all available software tools to enable an optimized and smooth work flow. The great demands of computation power for both modeling climate and hydrology are met by the application of the LRZ’s SuperMUC and Linux Cluster.
Further modules may be added inbetween B and Z in possible future projects and could also benefit from the unique climate dataset of ClimEx. This migth include agriculture, forestry, energy, ecology, health or any other field.
