  1. The ocean observing system for climate:requirements for SOT Albert Fischer and D. E. Harrison 4th session of the JCOMM Ship Observations Team Geneva Switzerland, 16-21 April 2007

  2. OOPC Terms of reference • Develop recommendations for a sustained global ocean observing system in support of the Global Climate Observing System (GCOS), the Global Ocean Observing System (GOOS), and the World Climate Research Programme (WCRP), including recommendations for phased implementation • composite and integrated sustained observing system developing information and products for climate monitoring, prediction, and research • Help develop a process for ongoing evaluation and evolution of the observing system and its recommendations • Support global ocean observing activities by involved parties, through liaison and advocacy for the agreed observing plans

  3. Where are we with plans? • OOPC shaped input from ocean research community into ocean chapter of the GCOS Implementation Plan (GCOS-92, October 2004) • composite and integrated observing networks • data systems • need for climate information and products • strong basis in ocean research community, incl. for evolution • high-level visibility and acceptance of these plans (UNFCCC, COP, G8, GEOSS, CEOS, IOC, WMO, JCOMM, GOOS) - but translation into national action requires continuous effort • recent (September 2006) extension of work on requirements for satellite observations (OOPC/GCOS and CEOS)

  4. CEOS response to UNFCCC (draft)

  5. The global ocean observing system for climatecurrent status against GCOS IP recommendations continuous satellite measurements VOS SOOP 57% April 2007 Total in situ networks 57% 100% • Data system 42% • Products and forecasts 81% 95% 43% 66% 21% 48%

  6. Ocean climate indices from data • Observing system evaluation • In the long term: the development of ocean forecasting and ocean reanalyses, and observing system simulation experiments (OSSEs) will provide specific feedback • Right now: estimating the uncertainty in the measure of climate indices • quantities that act as indicators of climate variability • towards a measure of our ability to observe • Liaison/outreach • A way to communicate about the ocean observing system and the ocean’s role in climate and climate variability

  9. Requirements for VOS / VOSClim • “Improve[d] meta­data acquisition and management for a selected, expanding subset of VOS (VOSClim) together with improved measurement systems.” (GCOS-92) • Handbook on Climate-Quality Meteorological and Flux Measurements at Sea • http://www.esrl.noaa.gov/psd/psd3/wgsf • intended for research fleet • possible to integrate the guidelines for VOS?

  10. Requirements for SOOP • 41 XBT/XCTD lines

  11. IX01, IX08, IX09N/IX10E, IX12, IX15/IX21, IX22 and PX02. CLIVAR-GOOS Indian Ocean Panel implementation plan (GOOS-152) priority XBT lines

  12. OOPC-11 (May 2006) recommendation for ITF Makassar Strait: ADCP mooring and PIES Inflow: Startup of a XBT/XCTD high-frequency (2-week) line extending from Mindanao (Philippines) to northwestern Irian Jaya (Indonesia) Outflow: Continuation of the IX1 XBT/XCTD high-frequency (2-week) line; as well as shallow pressure gauges in the outflow straights Interior: Continuation of the IX22/PX11 (north-south) and PX02 (east-west) XBT/XCTD lines across the Indonesian Seas at 2-week frequency Overview: Satellite altimetry and frequent reporting from the GLOSS tide gauge array

  13. Points for discussion • Need for clearer climate requirements for VOS • next agenda item • Incorporating guidelines for research ship met and flux measurements for VOS • Adequacy of SOT reporting against climate requirements • A better link between SOOP and the CLIVAR basin panels • line performance and possibilities • currently running, non-optimally, through OOPC • Evolved requirements for SOOP • priorities in Indian Ocean and ITF • Further discussion under V-4.1 (SOOPIP session Thursday) • OOPC encourages SOT to identify its requirements and potential contribution to a reinforced observing platform support center (JCOMMOPS)
