3 Presentation of the Group Terms of reference - Revised ToR EuroGOOS Coastal and Shelf Seas modelling Group Chairmen: Paolo Oddo and Ole Krarup Leth The EuroGOOS COastal and Shelf seas MOdelling Group (COSMO-WG) main objective is to establish a network of European experts from different coastal oceanography disciplines to discuss, promote and coordinate Coastal Ocean modelling (monitoring) activities in Europe. The main objectives of the COSMO-WG are: maintain a link between international efforts (with particular attention to the GODAE OceanView Coastal Ocean and Shelf Seas Task Team) and ongoing coastal modelling activities in Europe; maintain a continuous link between global/regional and coastal ocean operational activities at European Level, identifying the requirements to fill the gap between the different scales for a proper downscaling; Within EuroGOOS this link is needed, probably should be monitored at ROOSs level. The identification of the requirements to fill the gap can be addresses within this WG. monitor research activities associated with coastal and shelf seas at European Level; promote actions aimed at coordinating research associated with coastal and shelf seas activities; Next step identify coastal modelling requirements in terms of numeric and codes; address the issue of data assimilation in coastal areas; potential feedback from Coastal Systems, the issue can be probably only marginally addressed in this WG identify common protocols in coastal ocean model nesting and define a strategy for future works; Second step address the issue of model validations and routine observations in coastal areas; create a roundtable of recognized experts from different coastal ocean disciplines (physical and biogeochemical numerical modelling, data assimilation, remote and in-situ observations, validation and operational activities); 3

5 Activities Working Group on the Shelf Seas and Coastal Modelling has been established in The round table of experts (WG members) has been created. The first WG meeting was organized in Bologna (Dec 2012). During the meeting the ToR was revised, WG priorities and future steps were defined. The round table of experts in the different coastal modelling disciplines identified the necessity to draft a shared document (SD) on the relevant processes that can serve for the characterization of the "Coastal Ocean State" and how they are modelled or parameterized. The WG members started to draft the SD. The rationale behind this action is to collect info about local/regional actual practices in the different Institutions comprehending the largest number of cases to ensure generality of the research outcomes Some test areas were selected with the corresponding sub-set of processes typical to each area. Physical and relevant processes common to all the coastal areas considered have been identified. Further elaboration of the SD. Processes characterizing the European Coastal Regions connecting them with relevant scales and Events. Lists for all the selected regions the occurrence of common processes setting the priority in the modelling developments. 3 Major coastal modelling requirements (in terms of numeric and codes) have been identified (Rivers, mixing, geometry) Chairs Meeting in Bologna to review strategies short and long term goals and objectives the Coastal Modelling WG was represented and actively participated in the discussion at: the SAWG Meeting (Cork April 2013); EuroGOOS Executive Directors Board meetings; GODAE Coastal Ocean and Shelf Seas-Task Team (COSS-TT) meetings (Lecce Jan 2013, Puerto Rico Jan 2014) 5

6 Clearly the ToR GOALS Define Research priorities for Operational Coastal Modelling in Europe with particular focus on MSFD requirements Extract from the shared document R&D modelling activities to be proposed in HORIZON2020; In the document some physical factors and numerical development streams have been identified. What is needed: what is the current quality of operational modelling systems in reproducing / simulating / forecasting those factors? We need to collect this info from the nested systems in the different ROOSs. The final shape of the document should be: 1) introduction and Goals; 2) MSFD requirements; 3) current status and quality of the COPERNICUS Marine Core services; 4) current status and quality of the coastal operational models; 5) relevant processes characterizing the European coastal areas; 6) the model developments needed to improve the quality of the products. 6

7 Questionnaire for the coastal models : GOALS (How) To whom: to the ROOSs chairs asking to distribute to the coastal ROOSs members (+ Black Sea). Goal: EuroGOOS take actions in promoting funding support for developing coastal ocean operational models. The model developments should be driven by the MSFD requirements for the coastal areas monitoring system in support of management. So this questionnaire want understand what is the current status of the operational coastal models, what is the quality of the information provided in relation to the MSFD requirements and what are the needed steps in order to improve and reach adequate values. Time frame within HORIZON-2020, from 3 to 5 years. Connect with other ongoing activities Within NEMO (Nucleus for European Modelling of the Ocean, there are relevant activities that may be considered to design and define the coastal modelling developing strategies for operational oceanography in Europe: - a Working Group dedicated to the Ocean-Wave full coupling addressing the issue technically and theoretically; - shared efforts within the consortium members to develop NEMO capabilities to model the 1km oceanographic scales (1km effective resolution, 100m grid spacing), thus implements required physical processes with adequate numerical schemes (wet-and-dry, horizontal turbulence, high order schemes for advection). 7

15 Challenges Keep strong connection with EuroGOOS objectives/goals. Coordinate with other WG (SAWG) Some financial support would benefit the WG meetings Organization. The possibility to have dedicated sessions during EGU general assemble should be considered. Proposed Actions The Document addressing the priorities for Coastal Operational Oceanography should reflect the current European Operational Coastal Modelling requirements and thus a significant input from the community is needed. Alternatively the document can be circulate within the board and the other WG chairs for approval. 15
