Tuning of obs-error statistics
Results on SEVIRI impact :
Impact be similar to ATOVS data (AMSU-A or AMSU-B) assimilated in high resolution;
Impact depending on the parameters (Rh, Z) and model levels; Negative impact near the surface needs further tests with
more surface measurements (2m T, 2m RH) -coupled with SEVIRI

Evaluation
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->

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)
18-21 Sept 2007 9th COSMO meeting, Athens 31
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 on Lead Centres for specific areasLead Centers: o for researcho for operations
Results: Efficient use of the available
manpower. Specialisation of the NWP
teams.
