RC LACEEvaluation Project Evaluation after 10 years of common activities (1996-2006) • Goals: • To provide objective view of Project • To range a LACE to NWP objectives • To give independent advices about future development • Input for new LACE structure 2008-> 9th COSMO meeting, Athens
General recommendations (Quality of Project) • Strategy and planning (short-term, long-term; users demands) • Management structure (competence, authority) • Internal/external communications (WWW, visibility, NWP consortia) • Role of NWP systems at LACE centers (AAA models as the primary subjects) 9th COSMO meeting, Athens
Recommendations for Task Sharing Reasons: • To overcome the duplication of the operational efforts. • To suppress draining of resources on maintaining and downstream applications. • To provide small NWP centers with a complete NWP system. Methods: • Define the common tasks • Agreement onLead Centresfor specific areas • Lead Centers: • for research • for operations Results: • Efficient use of the available manpower. • Specialisation of the NWP teams. 9th COSMO meeting, Athens
LACE Future 2008 -> • Political decision for the closer operative cooperation (toward the Projects with operative deliverables) • Leading centers => Responsible center • Bottom-up => Top-down planning • Action Plan for implementation of (Working Group) • LACE 10-years strategy • LACE MoU III 9th COSMO meeting, Athens
