Presentation Transcript

  1. Argo Programme – activities in Japan – Keisuke Mizuno (JAMSTEC) • Argo is a global array of 3,000 free-drifting profiling floats that measure temperature and salinity of the upper 2000 m of the ocean. • Argo allows continuous monitoring of the global upper ocean, with all data being made open to public. • Argo is the sum of national contributions, coordinated by an international Steering Team, and endorsed by the WMO and IOC/UNESCO.

  2. Delayed mode QCed data Argo data flow Original data Satellite JMA JAMSTEC Ground station GTS Internet GDAC World-wide Meteorological agencies User Argo float Real time data are available within 24 hours Delayed mode data (High quality data) 6 months JAMSTEC: Japan Agency for Marine-Earth Science & Technology JMA : Japan Meteorological Agency GDAC : Global Data Assembly Center

  3. Japanese deployment Global Argo Network 2851 floats as of Mar.2007 Contribution : USA 54%, European nations 17%, Japan 14%, others 15% Sustained Argo network is indispensable for global ocean monitoring and climate change prediction

  4. Investigation of Ocean climate change Ocean heat content anomaly in 2005 (0-750m; by PMEL/NOAA) (p.s.u) Upper Ocean salinity anomaly in 2005 (0-100m; by JAMSTEC)

  5. Ocean prediction Climate Predictions Regional Predictions Models: consistent analyses

  6. JMA operational systems (Compass-k, ODAS) ODAS- Ocean Data Assimilation System for ENSO monitoring and predicting and two-tiered seasonal forecast (Global except Arctic and Antarctic Oceans) Compass-k - Analysis and forecasting system for the seas near Japan (North Pacific Ocean) ODAS Compass-k Subsurface Temperature Monitoring Subsurface Temperature Monitoring Equatorial transect (140E-80W, 0-300m) Sea Surface Temperature (NINO3) Prediction Sea Surface Current Prediction

  7. Prediction of climate changes ( e.g. Sea level rising, Shrinking Arctic sea ice cover, Extreme weather events….) safety and efficiency of maritime operations economic strategies (fisheries, agriculture,...) sustained use of ocean and coastal resources Achievement of Argo • Set up an ocean's climate warning system • Easy and open access to data &products Status/Prospect Operation Major Ocean data source for ocean/atmosphere prediction systems Research Better understanding of global changes and improved models for prediction

  8. High School students (Misaki Fisheries High.) deployed 10 floats High school kids are participating in float deployment, and enjoy pursuing their deployed float by internet and learn ocean environment.

  9. Pacific Regional Center JAMSTEC/IPRC Eq. CSIRO 30S http://www.jamstec.go.jp/ARGORC To ensure the consistency of data quality in the region, Regional centers are responsible for the delayed-mode data QC.
