Overview COSMO-CLM

The COSMO model in CLimate Mode (COSMO-CLM) is a nonhydrostatic regional climate model based on the Local Model (LM) of the Deutscher Wetterdienst and its succesor, the COSMO model. The LM has been developed by the German Weather Service (DWD) for operational weather forecast. Meanwhile, it is used and further developed by several other weather services organized in the COnsortium for Small-scale MOdelling (COSMO ) and is called COSMO model.

COSMO-CLM has been developed and is maintained by the CLM-Community. Since 2005, COSMO-CLM is the Community-Model of the German Cimate Research Community. The model has been used for simulations on time scales up to centuries and spatial resolutions between 1 and 50 km. CLM-Community members can use the starter package for COSMO-CLM as runtime environment for their experiments. The package contains everything that is necessary to run a simulation with COSMO-CLM.

The COSMO model system is a unified model system for Numerical Weather Prediction and Regional Climate Modeling. The development is done in close cooperation with COSMO. New developments and other source code changes have to follow the '' and must be communicated to the source code administrators.
