COSMO model

...

The COSMO-CLM is the climate mode of the COSMO model and the . The source codes of the individual model components  are identical with the COSMO model sources for each main model version.This documentation covers both modes are synchronized for each release of a main model version (e.g. 5.0) and are identical at that point in time.

The scientific documentation of the COSMO model is available on the COSMO webpage. All parts of the documentation for model version 5.00 (November 2013) and 5.05 (February 2018) are now holding a DOI and are stored permanently. The documentation includes the documentation of the COSMO model and , the pre-processing program INT2LM as well as , and a User's Guide. It is updated regularly.   However, it is never "up to date" since the documentation takes a lot of time. Recent developments are documented  documented in COSMO Technical Reports and in articles in the COSMO-Newsletters.There are no additional documentations of the source code modifications for the climate mode yet.

Standard references for the COSMO model and its components

A collection of scientific publications that can be used as standard references for the COSMO model and its components is available on the COSMO webpage (make sure that the box “only standard references” is ticked otherwise you get a list of COSMO releated publications): http://cosmo-model.org/content/model/documentation/journals/default.htm?core

Please cite the appropriate papers in your publications!

The COSMO model is written in FORTRAN 90 . The code development is based on the European standards for writing and documenting exchangeable FORTRAN 90 code. Its details Further regulations are specified in the “COSMO standards for source code development” (Appendix F of the CLM-Community Agreement; see Terms & conditions for the latest version).
