  5. KEY ISSUES • PARAMETERS’ HYPERSPACE COVERAGE • DESCRIPTION LEVEL • NEW INDICES & PROXIES • CHARACTERISTICS • PHYSICAL CONSISTENCY • RELIABILITY • QUALITY • SAMPLING RATE • AVAILABILITY • STANDARDISATION • PREDICTABILITY • FEASIBLE • RELIABLE • IMPROVABLE 5th ESWW, 20 November 2008, Bruxelles

  6. MAJOR OUTCOMES • STANDARD FOR INDICES EXIST IF INDICES ARE SATISFACTORILY COPED WITH BY VALIDATED MODELS (NO SHORT-TERM VARIATIONS ARE WELL REPRODUCED) • NO STANDARDS ARE SET FOR PREDICTION METHODS AS THEY ARE CONSIDERED NOT MATURE YET • NEW INDICES SHOULD BE ADOPTED WITH CAUTION TO MINIMIZE THE TOTAL AMOUNT • INDICES TUNED ACCORDING TO THE USERS’ NEEDS ARE OFTEN UNAVAILABLE 5th ESWW, 20 November 2008, Bruxelles

  7. FUTURE NEEDS • Activitypredictionmethods are needed and short-termvariationsshouldget more attention • Especialattentionshouldbepaidtousers’ inputsaboutspecificrequirementsforoperationalapplications • New indicesshouldbeadoptedbased on a well-verified and clearphysicalcontext • Long-termavailabilityofvalidatedindicesisrequested 5th ESWW, 20 November 2008, Bruxelles
