Several national meteorological services in Europe work together in a consortium for small-scale modelling (COSMO), the aims of which are the development, improvement and maintenance of a high resolution meteorological model.

The COSMO model is developed and used by the members of the consortium and their associated regional and military services, as well as by universities. It is employed for research and operational applications. The COSMO model works with a common source code that is used both for weather forecasting and for climate modelling.
