Consortium for Small-scale Modeling

consortium formed in 1998

The Consortium for Small-scale Modeling (COSMO) was formed in October 1998. Its general goal is to develop, improve and maintain a non-hydrostatic limited-area atmospheric model, to be used both for operational and for research applications by the members of the consortium (details). Moreover, within a licence agreement, the COSMO model may be used for operational and research applications by other national (hydro-)meteorological services, universities and research institutes.

The COSMO science plan calls for a harmonization of development of the COSMO and ICON (ICOsahedral Nonhydrostatic) models in the time horizon of 2020-21. Further development of the COSMO model has been reduced since 2019. Development and testing of new features are now restricted mainly to ICON.

It is therefore recommended to migrate to ICON, as the future operational model.

The COSMO-Model is also used by other academic communities, who adapted it to their needs:
