1. Observing System Status Report D.E.Harrison Ocean Observations Panel for Climate GODAE ST Washington, DC June 2008

2. OceanObs2009 Celebrate a decade of global observing, science and applications progress Invite the non-physical variable communities to agree their priorities and capabilities for sustained global observations Lay out a community-agreed path for global system activities for the decade ahead Lead to “2 nd Ed. GCOS-IP” for UNFCCC and GEO

3. Overview Global Ocean O.S. remains mostly in research world hands, motivated by research goals. Can this be sustained via science community? Regulatory drivers available? Possible? R&D and data system challenges, esp. for system evolution Good recent progress with ocean analysis and reanalysis, but much work ahead. GODAE performance metrics in development. Ocean climate information development proceeding slowly. Impact in coupled models?

7. Diurnal Scale Obs Feasibility of getting more frequent observations from surface drifters is anticipated. Working out implementation wrinkles still. Appears difficult to provide within forecast window without major new cost, but available on Svce Argos time frame.

10. Some in-situ OS Issues for GODAE How are XBT line data used by GODAE? Are broadcast mode XBTs useful? How are tide gauge obs used? How important is boundary current data? How useful are surface drifter displacement vectors? Ocean Sites obs? Subsurface ocean indices of societal importance are needed.

11. Sat. Info. Via Mark Drinkwater Global Monitoring for Environment and Security (ESA/EC contribution to GEOSS) The GMES Sentinel-1A, -2A, and -3A satellite units are fully approved and now under development. Sentinel-1 is C-band SAR with operational ocean & ice applications. Meanwhile Sentinel-3 has SAR altimeter, Ocean colour and ocean temperature (all collocated data streams). Currently looking for financing for the successor satellites i.e. recurrent units of Sentinels 1-3, together with additional Sentinels for atmosphere (Sentinel-4 and-5) at our Ministerial Council meeting in November this year. Earth Explorers - Research missions GOCE is complete and awaiting launch this summer 08. SMOS development and testing complete - waiting for launch date confirmation (end 2008) CryoSat-2 is almost complete and will be ready for launch next year. The remaining 3 approved Explorers (ADM-Aeolus; Swarm; and EarthCARE) are under various stages of implementation 6 new Earth Explorers under pre-feasibility Industrial study - results to be available towards the end of this year. ESA will hold a User Consultation Meeting in January -09 to decide on which missions are approved for Phase A study.

13. Ocean Satellite Status Summary Have not been able to find an update to the ‘bar chart’ diagram that was put together as part of the CEOS response to the GCOS-IP. Working for Jason-3 approval Opportunities being investigated w. Indian and Chinese missions. Ocean Satellite continuity is very much a work-in-progress.
