All internal and external relationships of COSMO are defined in an official Agreement between the national weather services of the participating countries.

There is no direct financial funding from or to either member. However, the partners have the duty of contributing actively to the model development by

• providing staff resources
• making use of research co-operation with national universities
• seeking national funding whenever possible.

A minimum of 2 scientists working for research and development within COSMO is required from each member.

In general, the group is open for collaboration with other NWP groups, research institutes and universities as well as for new members. For more information about the agreement, please contact the Chairman of the Steering Committe,

External users, like other hydro/meteorological services, or universities/research institutes, may use the COSMO model for operational and research purposes. For these, see the licencing policy.
