11. 3rd Workshop round tables The main objective of the round tables is to progress in the definition of the TTM, TTO and TS.  PS2b, PS3b, PS4b aims at better defining TTO. The main objective of these three round tables is to define the instruments that need to be deployed in sites/supersites or the research platforms needed. For each instrument/platform : scientific aims and how it includes in the overall program strategy, groups/persons in charge of deployment, funding status. A priority list could be established. Round table PS2b - Measuring air-sea fluxes and sounding the ocean  aims at defining TTO4 (Sounding the ocean), TTO5 (Measuring air-sea fluxes), and TTO6 (Measuring land-sea fluxes). Round table PS3b - Sounding the atmosphere  aims at defining TTO1 (Sounding the atmosphere), TTO3 (Measuring surface fluxes over land) and TTO5 (Measuring air-sea fluxes). Round table PS4b - Measuring surface fluxes over land and sounding continental surfaces  aims at defining TTO2 (Hydrological and soil measurement), TTO3 (Measuring surface fluxes over land) and TTO6 (Measuring land-sea fluxes).

12. 3rd Workshop round tables  PS1c, PS2c, PS3a, PS4a aims at better defining TTM. The main objective of these round tables is to make an inventory/coordination of modelling tools needed to answer the various objectives of HyMeX. For each modelling task: list of observations required for validation of models or for real time running (e.g. Data assimilation), leaders/core groups, funding information, priroity list. Round table PS1c- Multiscale modelling of the continental surfaces Round table PS2c - High-resolution (coupled, ensemble) modelling platforms for intense events. Round table PS3a - Regional climate modelling Round table PS4a - Real-time modelling platforms during SOP/EOP

13. 3rd Workshop round tables  PS1a, PS1b, PS2a, PS3c aims at better defining both TS and TTO (for the three first). PS1a - Long-term hydrometeorological observatories over ocean & PS2a - Long-term hydrometeorological observatories over land: The main objective of the round table is to identify the long-term ocean observatories or observations that contribute to the LOP (exemple of such long term observatories are for example MOOSE, OHM-CV or Lampedusa site). For each observatory: describe the associated scientific aims and identify some contact points for data access. A priority list could be established, as well as information about funding collected. PS1b - SOP/EOP sites and supersites: The main objective of the round table is to establish a list of hydrometeorological sites and supersites for SOP/EOP, focusing first on the first EOP/SOP (2011-2014). For each supersite: describe the associated scientific aims and to identify some contact points. A priority list could be established, as well as information about funding collected. PS3c - satellite products and data base: The main objective of the round table is to establish the satellite observations which are available and the elaborated satellite products needed/proposed. Contact points for realization and supply of satellite data could be collected. The second part of the round table could be dedicated to identifying the existing data bases, but also to agree on the project data base(s) for SOP/EOP.

24. Links GEWEX-HyMeX HyMeX aims at contributing to the WCRP-GEWEX objective of improving the understanding of the global hydrological cycle and prediction of its evolution by a coordinated set of studies targeted at the Mediterranean region, which, at present, is not covered by a GEWEX/CEOP RHP. As currently defined, the HyMeX program already complies with most of the criteria to become a RHP: In terms of hydrometeorological modelling, the development, validation and improvement of atmospheric and hydrological models, coupled or not. the involvment Numerical Weather Prediction centres and hydrological services. In terms of observations, easy access for scientists to already archived data and to new datasets collected during HyMeX, that can in turn serve as validation for GEWEX global data products, set-up of hydrometeorological sites for long term observation, that can fulfil the requested criteria to become GEWEX CEOP in-situ reference site or basin.  Identification of possible CEOP/RHP sites to be discussed during parallel session 2a (Wednesday, 3 – 10:30-12:30)
