3 Observation strategy «Nested» approach necessary to tackle the whole range of processes and interactions ti and estimate t budgets Enhanced existing observatories and operational observing systems in the key regions of high-impact events: budgets and process studies (+ dedicated di d short field campaigns) Enhanced current operational observing system over the whole Mediterranean basin: budgets (data access data policy ) EOP LOP Western Med + Greece Phasing with other international ti experimental programs (T-NAWDEX, HALO, MEDEX) SOP Eastern Med? Special observing periods of high-impact events in selected regions of the EOP target areas (aircrafts, ships, ): process studies

4 «Nested» approach for the 1 st EOP/SOP Observation strategy Heavy precipitation, flash-fllooding, dense water formation and ocean convection, severe winds and cyclogeneses, rivers (Rhone, intermittent rivers), coastal zones SOP Sub-basin EOP LOP

15 Final remarks The observation strategy is also designed for data assimilation and model validation purposes. The observation strategy includes also satellite observations. In-situ or on-board measurements designed also for validation of measurements in constrated topography areas or of new satellite missions (e.g. GPM/NASA) Thanks for your attention
