General Assembly 2 - JERICO - 3
WP9 MAIN OBJECTIVES
WP9 should apply sophisticated data assimilative models and statistical methods to demonstrate the impact of coastal observations in analyses and forecasts
Two types of experiments are carried out:1.Impact of existing observational platforms (OSE)2.Impact of future observational platforms (OSSE)

WP9 IMPACTS
ANY SUSTAINABLE COASTAL MONITORING SYSTEM SHOULD SHOW ITS IMPACT ON THE QUALITY OF MODEL ANALYSES FOR FORECASTING AND RECONSTRUCTIONS (RE-ANALYSIS) --- see major international groups like GODAE OCEANVIEW OSE-OSSE
OSSE OFFERS THE ONLY OBJECTIVE WAY TO ASSESS THE IMPACT OF NEW TECHNOLOGIES ON MODEL ANALYSES
OSE WILL HELP TO DEFINE THE MINIMUM OBSERVING SYSTEM REQUIREMENTS AND THE POSSIBLE GAPS OF SELECTED TECHNOLOGIES
INTEGRATION OF OBSERVATIONS AND MODELS GIVES THE STATE-OF-THE-ART DATA SETS FOR MSFD ASSESSMENTS
