Scientific context and objectives (1/3) • Background / Problem statement: Space Weather can affect ground and space technological systems as well as humans in space. Extreme conditions have economical consequences and may threaten safety and security of the technological infrastructures. In the US, important progress in developing Space Weather prediction systems has been made. Although Europe has much scientific expertise on the physics and effects of Space Weather, its optimal use suffers from a lack of coordination between the national research programmes.

Model Validation/Verification and Testing Components Model validation/verification —the comprehensive, systematic quantitative comparison of model output with observations—is required for identifying and documenting model strengths and weaknesses. Validation establishes evidence that the model represents the real system (or proposed real system) (Carson, 2002) – measures how well a model does what it is designed to do, including how numerically accurate it is (Vassiliadis, 2004) – strong requirement for the implementation of a model for operational use. Verification determines if a model implementation accurately represents the developer’s conceptual description of the model and its solution (Thacker et al. , 2004) - include both the computerized model verification and the evaluation of the model’s operational validity – follows the operational implementation of the model. COST is supported by the EU RTD Framework Programme ESF provides the COST Office through an EC contract
Recommendation for a V&V plan Ø Scientific evaluation - strong requirement for model improvements Ø Metrics based evaluation - operational use • Measure model usefulness for operations in comparison with some simple standard model. • Create simple measure of model capabilities (“one number”). • Allow objective comparison between models with comparable output. • Measure the improvement of model capabilities over time (usefulness of model upgrades). • Focus on parameters useful for operations.

Challenges (1/2) Problems 1. Lack of national support to the COST Actions in several counties (including Greece, Italy, etc…): Chair and vice-Chair have no support. 2. Transition to the CGS was not easy; lots of restrictions and penalties for the GH. But, COST office is always very helpful and responsive to our requests. COST is supported by the EU RTD Framework Programme 39 ESF provides the COST Office through an EC contract
Challenges (2/2) Critical phases to be implemented next year 1. Recommendation for Space Weather models validation criteria 2. Stimulation of models’ upgrades and of reliable computer codes Development of an online catalogue service for space weather resources http: //www. spaceweatherservices. com/spw_catalogue/ (Heynderickx, 2010). This prototype online catalogue database and web interface is currently undergoing evaluation and testing. Joint activities with BIRA for the upgrade of the European Space Weather Portal with models, catalogues and outreach material. An Mo. U has been established to describe the framework of this collaboration. 3. Intensification of the outreach activities 4. Organization of the 8 th ESWW 5.
