  2. What is Argo ? • Maintain a global array of 3000 profiling floats by 2006 (3°x3°) • « Take the pulse » of the Ocean’s upper layer in real-time • Complement to satellite and other in-situ observing systems • Access to data is free and unrestricted • Benefits: • Improve Ocean and Climate forecasting • Understand ocean-atmosphere interactions • Predict seasonal to decadal climate variability • Wide range of applications for high-quality global ocean analyses is anticipated

  3. Float Cycle

  4. Float Technology: complex & “revolutionary” • APEX, PROVOR, SOLO, NINJA, COPEX, NEMO • 150-200 cycles (4-5 years lifetime) • T/S Profiles down to 2000 dbars • CTD stable: 1 dbar, 0.001 °C, 0.01 Psu • Air/Ship Deployment • Argos Communications • Optical, Acoustic, Dissolved Oxygen sensors … • Iridium • Technological Challenge: path to operational

  5. Organization • GODAE/CLIVAR pilot-project • A major contribution to GOOS/GCOS • Endorsed by WMO and IOC • Argo Steering Team • Argo Project Office • Argo Information Centre • Argo Data Management Team

  6. Data Management • 2 channels of distributions: GTS of WMO and Internet • National Data Centres feeding GTS and Global Data Centers: Coriolis Server (IFREMER, France) GODAE Server (FNMOC, USA) • Real-Time standard QC applied • Delayed-Mode standard QC being finalized • Regional Centres • Long Term Archival Centre (NODC, USA)

  7. http://www.coriolis.eu.org • http://usgodae1.fnmoc.navy.mil/argo/argo.html Data collection and certification Prepare data for distribution Data sent ashore in hours Information about Argo Long term archive Here is the master copy of the data Regional analyses Argo Data System

  8. Project Status: • 1237 Active Floats (40 %) as of 11/05/2003R/T Data Publication: ~96% Deployments(target = 800/year) 2000: 1162001: 292 2002: 455 2003: 666 R/T status and statistics@http://argo.jcommops.org

  9. Project Status: Network Age • Logistical challenge: deployment opportunities

  10. Project Status: • 70 % of profiles > 1000 dbars • Argo = deep profiling

  11. Project Status: Participating countries + Mozambique, Pacific Islands, Netherlands

  12. International Issues: • EEZ access to complete the array • Float retrieval (1%): Argo label (~40%)

  13. Challenge: • Sustain the funding long enough to complete the global array and demonstrate its value.

  14. Challenge: • Sustain the funding long enough to complete the global array and demonstrate its value. • Continuous interactions between Research & Operational communities
