GODAE OceanView and its Task Teams

1. GODAE OceanViewand its Task Teams Andreas Schiller Centre for Australian Weather and Climate Research; Wealth from Oceans Research Flagship, CSIRO GODAE OceanView-CLIVAR Workshop, Santa Cruz, 13-17 June 2011

2. GODAE Achievements and Successes (1998-2008) • Implementation of observing and data processing systems • Argo and GHRSST (pilot projects), altimetry, in-situ • Implementation of global modelling & data assim. capabilities • High resolution and climate • Implementation of data/product serving capabilities • Inter-comparison / validation, metric and standardisation • Demonstration of feasibility and utility • Mesoscale nowcasting and forecasting, ocean climate research, • marine pollution and safety, weather forecasting, marine • resources, etc. • Scientific advances • Modelling, data assimilation, scientific validation

3. Feasibility of Now-/Forecasting of Ocean Mesoscale Hurlburt et al, 2008, AGU Monograph 177

4. The New Challenges (1)Face emerging new societal needs • Understand/monitor/forecast the earth system from days to decades • Improve atmospheric forecast where the ocean impacts it (cyclones, monsoons, …) • Application of ocean prediction techniques to improve climate anddecadal prediction including the ocean contribution • Where (most) people live • Improve near-shore/coastal waters real-time prediction (coupling to and/or downscaling from the offshore/deep ocean; physics, biogeochemistry) • Understand the impact of climate change in coastal regions (downscaling) • For the sustained exploitation of the seas • Develop ecosystem-based management of marine living resources  Support environmental policies through environmental monitoring

5. The New Challenges (2)Improve and extend our capacities • Research and development in ocean modeling, data assimilation • Coupling with other components of the earth system • Cooperation with international research programs (e.g. WCRP, IGBP, SCOR)  Improve accuracyof the environmental information and products

6. The New Challenges (3)Better observe the ocean • Help the international organizations in charge of the development of the ocean observing systems: • For the transition to sustained operations of the global in situ and space observing system • better use of existing systems, such as ARGO, Jason, … • For the design/assessment of new observing systems • new observable (e.g. bio, …), new focus (e.g. coastal, …) • For the optimization of the resources • measure the relative impact, assess the utility, etc… through OSE/OSSE  Evaluate benefitand optimizeuse of the GOOS

8. GODAE OceanView: • Establishment of the GODAE OceanView Science Team in 2008/09 • Five Task Teams • International Patrons • New members • Work Plan 2009-2013 • GODAE OceanView web site • Summer School Perth 2010

9. GODAE OceanView Forecasting Systems • National systems involving • research & operational systems • BLUElink – Australia • Brazilian Consortium • Canadian Consortium • NLOM and NCOM – USA • HYCOM Consortium – USA • ECCO – USA • Indian Consortium • Move & COMPASS-K – Japan • China • MERCATOR – France • MFS – Italy • NCOF (FOAM) U.K. • TOPAZ – Norway • European coordination • ECMWF • myOcean

10. To be Achieved by GODAE OceanView • Improve accuracy and utility of ocean analysis and forecasting products • Promote the development of downstream useof ocean data and information products from GODAE OceanView systems • Support the transition to operational services Links with JCOMM/ET-OOFS (lead) • Demonstrate the valueof theobserving systems • Coordinate the development of new capabilities and links to other communities (international relationships)  job of task teams

11. GODAE OceanView Task Teams TASK TEAMS address specific topics of particular importance to GODAE OceanView require collaboration with international research programs or other groups (e.g. coastal community): Inter-comparison and Validation (Martin & Hernandez) Observing System Evaluation (Oke & Larnicol) Coastal Ocean and Shelf Seas (DeMey & Kourafalou) Marine Ecosystem Analysis and Prediction (Barciela & Brasseur) Short- to Medium-Range Coupled Prediction (Brassington)
