GODAE assimilation systems continue to improve forecast accuracy in the blue ocean (e.g., Kuroshio) but still gross errors in some eddy-rich areas. Need more detailed currents in coastal and shelf seas Higher resolution models Nesting is preferable to direct use Tides must be included at some stage Improved forcing from atmosphere (high-resolution, high freq data) Assimilation of current data (HF radar, drifters) Need measures of accuracy to propagate into oil spill forecast results! GODAE & oil spill forecasting Future perspectives Data access and accuracy GODAE Final Symposium, 12 15 November 2008, Nice, France Funding for Argo & altimetry still not secure Development of good quality systems & forecasts took longer than expected Engaging interest of downstream users harder than anticipated Resources did not always match ambition -Many national teams resources were limited or delayed -Heavy reliance on a few special people (Christian, Neville, Michele, ) -Pro-active coordination from Project Office started late Difficulties GODAE Final Symposium, 12 15 November 2008, Nice, France Sustaining the global ocean observing system We need full statements of our prioritised requirements for research, development and operations as well as short-term priorities for advocacy Sustained observations are essential for climate research as well as operational services The observing systems required for climate research and weather forecasting provide much of the backbone of the observation system needed for operational services Global collaboration and coordination is essential to achieve best value for money S & T development of satellite systems that are fully effective and as efficient as possible and hence fit for operational use is a long & demanding process. This is insufficiently recognised and a major factor in funding crises GODAE Final Symposium, 12 15 November 2008, Nice, France The global ocean observing system recommendations Main requirements based on discussions over the last few years: Sustaining Argo and the global in-situ ocean observing system (GOOS, GCOS, JCOMM) Sustain altimetry. 3-4 altimeters required: only plausible way to initialise ocean mesoscale. Need long term time-series of Jason satellites (climate reference). High precision and all weather SST needed as part of combined satellite/in situ SST measurement system to give highest absolute accuracy (and resolution) (GHRSST strategy) Sea-ice characteristics (microwave, SAR) Ocean colour (visible imagery) and development of an in-situ observing system for biogeochemical parameters using new methods is increasingly important + Extend the observing systems to shelf and coastal zone GODAE Final Symposium, 12 15 November 2008, Nice, France Proposals for future coordination From an experiment towards a long-term ocean&analysis forecasting international program GODAE OceanView GODAE Final Symposium, 12 15 November 2008, Nice, France Evolution of GODAE systems Most GODAE groups have or are now transitioning towards operational or pre-operational status. GODAE systems need continuous improvements and should benefit from scientific & technological advances in data processing, data serving, modeling and data assimilation (incl. evolution of the observing system). GODAE systems are also evolving to satisfy new requirements (e.g. coastal zone and ecosystem monitoring and forecasting, climate monitoring and reanalysis). Challenges require international collaboration and cooperation GODAE Final Symposium, 12 15 November 2008, Nice, France New societal demands, more pressing requirements for our systems Integrated descriptions of ocean state and characterisation & detection of climate change in the ocean Forecasting in shelf-seas & coastal waters Monitoring and management of the marine environment (including biogeochemistry & ecosystems) Development of improved weather & climate predictions (near coasts, weather, tropical cyclones, monsoons, seasonal and decadal predictions) Assessments of uncertainty in downscaling climate change predictions to coastal regions GODAE Final Symposium, 12 15 November 2008, Nice, France GODAE OceanView Objectives Provide international coordination and leadership in: The consolidation and improvement of global and regional analysis and forecasting systems (physics) The progressive development and scientific testing of the next generation of systems covering bio- geochemical and eco-systems and extending from the open ocean into the shelf sea and coastal waters. The exploitation of this capability in other applications (weather forecasting, seasonal and decadal prediction, climate change detection and its coastal impacts, etc). The assessment of the contribution of the various components of the observing system and scientific guidance for improved design and implementation of the ocean observing system. GODAE Final Symposium, 12 15 November 2008, Nice, France Proposals for future coordination: the main/key points Retain a working-level scientific steering team responsible for a program of activities implemented at national level a core activity (modeling and data assimilation) an active Project Office and engaged Patrons group Develop or strengthen Task teams developing new capabilities in cooperation with other relevant international programs (CLIVAR, IMBER, OOPC,..) Links with observing systems (Argo, OST, GHRSST, space agencies) reporting to IOC, GOOS & CEOS Coordinate with and complement the new JCOMM Expert Team on Operational Oceanographic Forecasting Systems (ET-OOFS) GODAE Final Symposium, 12 15 November 2008, Nice, France GODAE OceanView Science Team CORE ACTIVITIES. A forum where the main operational and research institutions involved in global ocean analysis and forecasting can develop collaborations and international coordination. TASK TEAMS. These teams will address specific topics of particular importance to GODAE OceanView that require collaboration with international research programs (e.g. OOPC, CLIVAR, IMBER, SOLAS, WCRP) or other groups (e.g. coastal community). JCOMM. Operational aspects related to product harmonization and standardization and links with JCOMM will be carried out by the JCOMM ET-OOFS. GODAE Final Symposium, 12 15 November 2008, Nice, France Proposed Initial Task Teams Intercomparison and Validation in cooperation with JCOMM ET-OOFS and CLIVAR GSOP Observing System Evaluation coordinated experiments; new techniques; with OOPC Links with observing system agencies Coastal Ocean and Shelf Seas Coupling open ocean/coastal zone. Seamless transition from the open sea down to the coastal zone. Marine Ecosystem Monitoring and Prediction In cooperation with IMBER Others to be defined later in relation with other communities (e.g. coupled data assimilation NWP community) GODAE Final Symposium, 12 15 November 2008, Nice, France Science Team and Patrons The Science Team will consist of up to 30 members and include leading scientists from operational systems experts in key scientific fields representatives of key components of observing system chairs of Task Teams The Science Team will be co-chaired by Andreas Schiller and Eric Dombrowsky The Patrons group will be invited to Science Team meetings and provide advice on resources and funding priorities GODAE Final Symposium, 12 15 November 2008, Nice, France Summary Operational oceanography faces many challenges with time scales ranging from weather to climate. It is inherently an international issue, requiring (long term) collaboration. GODAE OceanView will promote the development of ocean modelling and assimilation in a consistent framework to optimize mutual progress and benefit. It will consolidate and improve existing systems and through cooperation with other programs will extend their capabitlies (climate, coastal, ecosystems) and application areas. It will also promote the associated exploitation of improved ocean analyses and forecasts and provide a means to assess the relative contributions of and requirements for observing systems.
