  1. New Generation Sea Surface Temperature for Monitoring the East Asian Seas Hiroshi KAWAMURA Graduate School of Science Tohoku University

  2. GHRSSTNew Generation SST Ver.1.0 （2001) Geostationary Met. SatelliteHourly Infrared TMI SSTMicrowave SSTCloud free Merging by objective analyses AVHRR、VIRS Cloud-free, High Resolution, Quality-Controlled5 Km Spatial Resolution, Daily SST Product

  3. Warm-core ring off the Japanese Pacific coast 15 June 1982 Kawamura et al. (1986)

  4. Moving oceanic structure !!19-28 May in 1982 • High-resolution SST images capture the synoptic oceanic structure • AVHRR can detect the moving oceanic structure • Kawamura et al. (1986) In order to forecast fluid motions, information of the targeting phenomena are needed to be included in initial conditions of the forecasting model

  5. Establishment of NOAA receiving station (1988) - Generation of real-time regional high-resolution products - Dissemination of 5-channel products by internet Computer Network University Computer Center Japan Image Data Base: (JAIDAS) - JD_E (Eastern Japan) 1990-- JD_W(Western Japan) 1994-1 Million access in a year (2000)

  6. Ultra High Speed (Super) computing of AVHRR SST • Computer Center of the Tohoku University • SX- 4 Super Computer • Ver.1.0 15-minutes/scene (1997) • Ver.2.0 5-minutes/scene (1999) - Ten-year time series of the High-resolution SSTs images (0.01゜grid, 4000x4000 pixels)

  7. VISSR reception + Super Computing + Internet MTSAT SST TRITON SST 30 Archive MTSAT correctly captured the ΔSST in clear condition Geostationary Satellite (1996)

  8. Preparatory works for New Generation Sea Surface Temperature • Establishment of the AVHRR/GMS systems • Network-based dissemination of real-time high-resolution satellite products • Regional satellite SST Cal/Val and algorithm development (AVHRRs since 1988, Geostationary VS/IR radiometers since 1996, MOS-1 SST, ADEOS1/OCTS standard algorithm, ADEOS2/GLI standard algorithm) • Many application researches

  9. Global SST product > ADEOS-II SST ADEOS-II SST: Combination of infrared, microwave and in situ SSTs (1998) • GLI infrared SSTs: • High accuracy, fine spatial resolution, wide coverage • AMSR microwave SSTs: • Retrieval of SSTs under clouds, wide coverage • In situ SSTs: • Standard and reliable SSTs, anchor points for the satellite SSTs

  10. Prospectus for a GODAE SST Project (March 2000) GODAE has a fundamental dependence of SST data and products In particular, global perspective of GODAE demanded attention to the many gaps in present products (many not quantified) and improved representation of observational errors in data products Cloud Mask for IR Measurement and Diurnal Cycling of SST (Including the Bulk-Skin Problem) Increase its temporal and spatial resolution largely Less than 10km and Less than 24 hours

  15. New ChallengeTechnology transfer to the regional seas (Northeastern Asian Marginal Seas) • Science and Technology leads • - From science to operation • Use modern technology (Network/Computer) • Regional international framework • IOC science programme (From science) • NEARGOOS (To operation)

  16. IOC/WESTPACOcean Remote Sensing Programme Programme TOR: / Promote of application activities using satellite observations in the WESTPAC region (Introduction of the New Technology)/ Conduct international remote sensing projects for better understanding of the WESTPAC region and development of applications (Demonstration of the New Technology) / Contribute to the regional GOOS through the above-mentioned activities (Design and Implementation of the New observing system) Satellite + Computer + Network 1) New generation SST project (Kawamura)- Development of coastal high-resolution SST (Science and Technology development)- Contribute to NEAR-GOOS 2nd phase
