Abstract
The history of the COSMO (COnsortium for Small-scale Modelling) model goes back to the early 1990s, when the Deutscher Wetterdienst (German Meteorological Service, DWD) decided to develop a non-hydrostatic model, the Lokalmodell (LM) [...]
Highlights
A non-hydrostatic kernel that allows for mesh sizes lower than ten kilometers, a modern, clear and modular programming, seemed to be reasonable criteria for the development of a regional climate model
Scientists from BTU Cottbus (Germany) and GKSS Research Centre (Germany) joined the developer group and together it was possible to develop the first climate version of the Lokalmodell, which was completed in summer of 2002
Based on these evaluation runs, the community carried out an intensive validation of the CLM with a focus on the ability of the model to serve as a regional climate model
Summary
A non-hydrostatic kernel that allows for mesh sizes (much) lower than ten kilometers, a modern, clear and modular programming, (including the efficient MPI parallelization) seemed to be reasonable criteria for the development of a regional climate model. Scientists from BTU Cottbus (Germany) and GKSS Research Centre (Germany) joined the developer group and together it was possible to develop the first climate version of the Lokalmodell, which was completed in summer of 2002. In fall 2004 PIK, GKSS and BTU Cottbus presented the new regional climate model and invited all interested scientists to join the developer group and establish a network for the coordinated and systematic development of the CLM.
