  3. LOP EOP 2010 2010 2013 2014 2015 2016 2016 2017 Eastern Med ? Observation strategy • « Nested » approach necessary to tackle the whole range of processes and interactions and estimate budgets Enhanced existing observatories and operational observing systems in the key regions of high-impact events: budgets and process studies (+ dedicated short field campaigns) Enhanced current operational observing system over the whole Mediterranean basin: budgets (data access  ‘data policy’) 2010 2011 2012 2013 2014 2017 2018 2019 2020 Western Med + Greece SOP Phasing with other international experimental programs (T-NAWDEX, HALO, MEDEX) Special observing periods of high-impact events in selected regions of the EOP target areas (aircrafts, ships,…): process studies

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

  5. Insights into the Implementation Plan Monthly frequency of intense cyclones (ERA40 1957-2002) (Homar, 2007) J F M A M J J A S O N D SOP1: 15 Sept.- 15 Nov. Heavy rainfall and flash-flooding, Ocean state prior the dense water formation Dense water propagation for SOP1.2 SOP2:March-April Dense water formation and convection formation Cyclogeneses and severe regional winds SOP2.1 SOP1.2 SOP2.2 SOP1.1 • SOPs/EOP in Western Mediterranean EOP Sept. 2010 Sept. 2012 Sept. 2011 Sept. 2014 Sept. 2013 March. 2013 March. 2012

  6. Insights into the Implementation Plan MOOSE: Mooring, buoys --- Glider transects EOP : --- XBT on 3 ferry lines (1/w) 20-30 ARGO free-drifting floats / 5 days Observation of the ocean and atmosphere over the Sea

  7. Insights into the Implementation Plan MOOSE: Mooring, buoys --- Glider transects EOP : --- XBT on 3 ferry lines (1/w) 20-30 ARGO free-drifting floats / 5 days Observation of the ocean and atmosphere over the Sea

  8. Insights into the Implementation Plan MOOSE: Mooring, buoys --- Glider transects EOP : --- XBT/15 milles on 3 ferry lines (1/w) 20-30 ARGO free-drifting floats / 5 days SOP: 1 research vessel dedicated to networking the northwestern Mediterranean (air-sea fluxes, ocean measurements) Observation of the ocean and atmosphere over the Sea

  9. Insights into the Implementation Plan SOP: 1 research vessel dedicated to networking the northwestern Mediterranean (air-sea fluxes, ocean measurements) 1 research vessel dedicated to intense events, on alert (atmosphere sounding, precipitation, air-sea fluxes and simultaneous measurement of ocean and atmospheric boundary layers ). MOOSE: Mooring, buoys --- Glider transects EOP : --- XBT on 3 ferry lines (1/w) 20-30 ARGO free-drifting floats / 5 days Observation of the ocean and atmosphere over the Sea

  10. Insights into the Implementation Plan German HALO aircraft missions: SOP1.1 and ? HALO-THORPEX (T-NAWDEX, 50h upper levels) HALO-NEPTUNE (Medit, upper levels) French research aircrafts (SOP1 & SOP2) ATR42 (low and middle troposphere) & Falcon20 (upper levels) Observation of the atmosphere USA research aircraft : SOP1 & SOP2.1 NRL/P3 ELDORA (cloudy and precipitating systems) German DO128 aircraft : (Boundary layers)

  11. Insights into the Implementation Plan Radiosoundings: Increased frequency of some existing RS during EOP (2/d -> 4/d) ( ) High temporal frequency during SOP ( ) + additional RS sounding ( ) Observation of the atmosphere ? ? CNES Balloons: Boundary layer Pressurised Balloons from Med. islands or North Africa Aeroclipers for measuring air-sea fluxes ?

  12. Insights into the Implementation Plan Hydrometeorological sites “Ticino” “Adige” “South-eastern France” DLR Supersite (Ebro valley): POLIRAD Radar, disdrometers, micro-rain radar, cloud radar “Corsica” (Charmex-HyMeX) ? ? “Catalonia” ? IMK Supersite (Balearic, Corsica) : Soundings, Doppler wind lidar, cloud radar, energy budget stations, atmospheric surface and soil moisture measurements

  13. SOP or EOP: • - several mobile radars (LAMP; NSSL, USA; New Zeland, Univ. Honenheim) • - water vapour lidar and aerosols (IGN-SA) • - water vapour and Temperature lidars (Univ. Honenheim), • - electricity receiver PROFEO (ONERA) • CCN/IN measutrements (LAMP; CNRM) • GPS receivers (GM) • soil moisture measurements (CNRM, HSM) • Disdrometers (LTHE) • LS-PIV discharge measurement (CEMAGREF) Insights into the Implementation Plan Southeastern-France site Hydrometeorological supersites SO OHM-CV Sediment transport and erosion Flash-flood hydrometeorolgy ORE Draix Gardons ORE MEDYCYS Urban meteorology Kastic systems Marseille

  14. Insights into the Implementation Plan radars Lidar vapeur d’eau Raman LINET Other networks for EOP/LOP Wind profilers GPS

  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
