Presentation Transcript

  1. The Activities of Andrea Kaiser-Weiss GHRSST Project Officer, based at NCEO, University of Reading, UK

  2. Outline • Why Sea Surface Temperature (SST) and why GHRSST (Group for High Resolution SST) • GHRSST Data Flow • GHRSST in the International Landscape • Planned Future • Summary

  3. Why SST : Storms Kerry A. Emanuel (April 2010)

  4. Why SST: Rainfall variability Rainfall EOF’s Long-term change Correlated SST Giannini, Biasutti, Held and Sobel, Climatic Change, 2008

  5. Why: Climate change 1961-1990 average: 13.97 C Source : BoM graphics from HadCRUT3v data Heat content (1022 joules) Global ocean heat content in the upper 700 m. Climate Change Indicators in the United States, p 36, EPA 430-R-10-007, April 2010.

  6. Motivation : Oceanography Surface Trend (ºC/10 yrs) 1950-2010 Source : BoM graphics from HadCRUT3v data • SST related science in Oceanography : • air/sea flux • currents, eddies, fronts • AMO • trends in all of the above

  7. Why SST ? • Ocean modelling and forecasting • NWP (hurricanes, seasonal-interannual rainfall variability) • Climate variability and change • Ecosystems (habitats, aquaculture) • Fisheries • Navy acoustic signal processing

  8. Why GHRSST ? MTSAT-1R Imager AQUA AMSR-E MODIS MSG-SEVIRI Imager TRMM TMI GOES Imager METOP POES AVHRR ENVISAT AATSR Credit: C. Gentemann

  9. Why GHRSST ? GHRSST IX (2008): “To develop and nurture cooperation and progress at the world scale in the subject area of satellite Sea Surface Temperature”

  10. GHRSST Builds on EO complementarities… DataMerging • Polar infrared has high accuracy & spatial resolution • Geostationary infrared has high temporal resolution • Microwave Polar orbiting has all-weather capability • In situ data provide reality in all weather conditions

  11. Definitions of SST SST – SST10m (K) 0 0.5 1.0 1.5 2.0 2.5 3.0 10mm 1 mm Daytime, light winds SSTint interface sea surface temperature 1 m Night-time, or strong winds SSTskin sea surface skin temperature Depth SSTsubskin sea surface subskin temperature SSTfnd sea surface foundation temperature SSTdepth sea water temperature at depth z, e.g.,SST2m 10 m

  12. GHRSST Data Flow

  13. Combining satellite data: MyOcean L3 (Europe)

  14. US: for example MUR analysis by Mike Chin at JPL

  15. User tools and Services • NAIAD and dataminer • IFREMER and JPL • SQUAM • GMPE • HRDDS • WMS • G1 OurOcean • DataCasting

  16. Estimation Methods EARWiG Diurnal Variability DV-WG Lake Surface Water Temp. LSWT-WG Data Assembly and Systems DAS-TAG High Latitude HL-TAG Applications and User Services AUS-TAG Inter-comparisons IC-TAG Reanalysis RAN-TAG GHRSST Organisation CEOS-VC International Stakeholder Advisory Council GPO : GHRSST International Project Office International GHRSST Science Team SSES and Validation STVAL-TAG Rescue & Reprocessing Historical AVHRR Archives R2HA2-WG User Requirements for high resolution Sea Surface Temperature data products and services from operational, scientific, and climate communities.

  17. 3. GHRSST in the international landscape GHRSST = well linked to the national and international space agencies, Met-offices, and major research institutes (e.g. Navoceano, NOAA) GHRSST interaction with NASA SST Science Team, ESA CCI, MyOcean, Australia, Japan, New: South Korea, Brazil, Canada, China, India . Links to CEOS, GCOS, WMO, JCOMM, WCRP, OceanView, ET-OOFS, …

  18. Planned Future for GHRSST: CEOS SST Virtual Constellation (SST-VC)

  19. Summary • GHRSST mission: to provide SST to operational users and a to a massive science community • GHRSST priority research: uncertainty estimates, Sensor Specific Error Statistics • Research issues: variability in the upper ten metres cloud detection, long-term stability • Users: which SST should they be provided with ? reliable GHRSST operational mature

  20. GHRSST XII Science Team meeting 2011 Edinburgh, Scotland, 27 June - 01 July Special emphasis is on facilitating the exchange between data users and producers. Please indicate your interest by sending an email to ghrsst-edinburgh2011@reading.ac.uk
