The third ALADIN Memorandum of Understanding was signed on October 21^st, 2005 during the 10^th ALADIN Assembly in Bratislava. It is valid for at least 5 years after signature .

An amended version was signed during the Extraordinary General Assembly (Brussels, Feb 2006) : it defines more precisely the relationships between governing bodies with a proposed way of circulating information, request and decision between GA, PAC, PM and Directors on one hand, in consistency with HIRLAM and with ECMWF.

A third signing in nearly identical terms, but at 16 Partners, of a new version of the ALADIN MoU3 took place during the 13^th General Assembly. The only differences with respect to the 2^nd version (2006) are fourfold: number and explicit names of Partners; provision for not extending the duration of the MoU3 at the occasion of its present new signing; footnote added on request of Turkey and following the decision of the Budapest General Assembly two years ago; an updated Table of cumulated manpower participations, allowing inter alii the Turkish contribution during the Acceding Membership phase to appear.

The 3^rd MoU defines :

• the purposes and objectives agreed by the Parties for ALADIN cooperation
• the condition of membership, the rights and obligations of the members
• the governance and the management : General Assembly (with its Chairperson and Vice-Chairperson), Program Manager, Policy Advisory Committee, ALADIN Local Teams Managers, Program Team, Committee for Scientific and System/maintenance Issues, System/maintenance and Scientific Coordinators, Support Team
