Please, do not forget to state that you used the “COSMO model in Climate Mode (COSMO-CLM)” and, please, also include the statement “COSMO-CLM is the community model of the German regional climate research community jointly further developed by the CLM-Community” in each publication.
Please remember, that part of your scientific success relies on the work of those people providing the reference model setup, maintain the codes, etc. Therefore, it would be more than a sign of courtesy to offer them co-authorships once in a while.

Special information for new members of the CLM-Community on the structure of the community and on the first steps with the model COSMO-CLM are provided in the section 'For Beginners'
Report bugs in the model code (INT2LM, CCLM) through the RedC website .
Please report a potential bug first in the forum. In case it turns out to be a real bug, it can be added as such under the "new issue" menu (only managers, developers and reporters have permission create a new issue).

Initial- and Boundary Data
For some GCMs programs to convert the forcing data to INT2LM-format are already available. At the HPC system at Deutsches Klimarechenzentrum (DKRZ), some already converted datasets are available. An overview can be found here .
The namelist parameters are described in the User Guide of the COSMO model and also in the Namelist-Tool . The namelist settings for configurations for different regions and/or resolutions are also available in the Namelist-Tool .
Output parameter list
An overview of the possible output variables of COSMO-CLM is availalbe here.
The 'SAnity check for MOdels of the Atmosphere' -Tool is part of the COSMO-CLM Starter Package. The tool checks for some output variables if the values are within a reasonable range. The given margins in the file samoa.list might to be adapted according to the model domain.
The source codes of the recommended version of COSMO-CLM and INT2LM can be downloaded from the RedC . The user name and the initial passwort have been sent to each community member in the Welcome E-Mail.
Runtime environment for ICON-CLM. SPICE (Starter Package for ICON-CLM Experiments) is available via RedC together with further information and on Zenodo.
Starter package (COSMO-CLM)
Contains everything to run a COSMO-CLM simulation. The starter package is available via RedC .
