WG SUPTECH strongly recommends to use ONLY the recommended COSMO-CLM configuration for simulations in of the EURO-CORDEX domain (visit the namelist-tool for detailed information about the setup). For every other configuration, even if it is only slightly different compared to the recommended setup (e.g., domain size, resolution, atmosphere height, time step, tuning parameters, etc.), tests are necessary to verify the reliability of the new configuration. These tests should include tests with at least two different time steps and the results for PMSL should be analyzied (e.g. RMSE). If the values differ significantly, the results should be analysed against compared to observations or a simulation with a third time step should be performed to figure out which of the previous simulations is more reliable. Please considerbe aware, that the time steps of-course need have to fulfil the CFL criterion in any case.
If you want to run the model on another domain than Europe, you should follow the following steps to get a reasonable model setup:
