Since the beginning of the project, management meetings have taken place regularly; their form and their organisation have changed accordingly to the governances established by the different MoU.

• AWOC meetings : Discussions about portability of the ALADIN code to different platforms and problems linked to operational implementation were the main topic of the AWOC group that met between 1997 and 1999.
• informal meetings : Between 1990 and 2005 (thus, before the formalization of the 3^rd MoU), informal ALADIN meetings were often organized besides the annual EWGLAM & SRNWP meetings.
• first informal meetings with HIRLAM
• meetings for the MoU renewal
• meetings to prepare the scientific plans
• CSSI meetings: In 2002, a CSSI (Committee for Scientific and Strategic Issues) structure, a coordination team of 6 persons nominated by the 6^th Assembly of Partners had been shelved when launching the ALADIN-2 project. This first attempt didn’t prove very successful and the 9^th Assembly of Partners (2004) decided to both push forward and renew CSSI. A new definition of the CSSI appears in the 3^rd MoU.
• AA, AAA, TCWGPDI, meetings
