HIRLAM : ALADIN had a research cooperation with HIRLAM for years; an enhanced cooperation started in 2004 and a Cooperation Agreement between the ALADIN consortium and the HIRLAM consortium was first signed on December 6, 2005 and renewed on December 1st, 2010: the respective strengths and weaknesses of both consortia complement each other well and, in the recent years, in the so-called "HARMONIE" ( Hirlam Aladin Research on Meso-scale Operational NWP in Euromed) dynamics, ALADIN and HIRLAM have collaborated more and more closely, giving a new impulse to the European structuring of NWP activities.
LACE : ALADIN has strong links with LACE, LACE being a grouping of ALADIN members, using aladin software : first operational ALADIN-LACE model was run in Toulouse where the LACE management group was hosted (1994); in 1998, the LACE operations were transfered to Prague Regional Center; from 2003, each RC LACE Member is responsible for its own operational NWP system, but scientific research and development is co-ordinated within the LACE project.
