  1. Medspiration 4th and Globcolour 1st UCM Overview of Progress in Medspiration Ian Robinson, Project manager

  2. Outline of Medspiration Project Status • Background to the Medspiration Project • Overview of the Medspiration Service • Summary of Operation • Recent Developments • Looking forward Medspiration 4th and Globcolour 1st UCM

  3. A brief history of Medspiration • 2001-2003 GHRSST-PP establishes methodology for complementary use of SST from different sources • GODAE High-Resolution Sea Surface Temperature, Pilot Project • GHRSST Data-processing Specification (GDS 1.5) agreed • 2003 ESA proposes Medspiration project (part of DUE) • GHRSST is the “Key User” to whom ESA responds • The European regional data assembly centre (RDAC) for GHRSST • European User requirements document for SST is produced • ITT issued July 2003. Contract confirmed Dec 2003. K/O 1-01-04 • 2004-5 Phase 1 of Medspiration • System Requirements Review: 4-5 Mar, 2004 • Critical design review: 14th July, 2004 • Qualification Review: 24-26 Nov, 2004 • Beta Test: 1-28 Feb 2005 • Acceptance Review & 1st UCM : 22-23 March 2005 Medspiration ConsortiumNational Oceanography Centre, Southampton (Prime)Ifremer, BrestMeteo-France (CMS, Lannion) CLS , ToulouseCNR, RomeMet.No, OsloVega plc, UK Medspiration 4th and Globcolour 1st UCM

  4. Data Fusion Quality Control To facilitate the movement of data User Applications The GHRSST-PP Concept • In principle, the merging and analysis of complementary satellite and in situ measurements can deliver SST products with enhanced accuracy, spatial and temporal coverage. Medspiration 4th and Globcolour 1st UCM

  5. The Issues GHRSST grappled with • Different types of SST from different sources • Skin • Sub-skin • Biased to buoy observations (~ 1m depth) • Different sensor types • Infra-red limited by cloud but offers fine spatial and radiometric resolution • Microwave radiometers penetrate cloud, but have coarser resolution • Different sampling characteristics • Polar orbit, wide swath, ~ 1 km resolution (IR) • Polar orbit, wide swath, 25 – 60 km resolution (MW) • Geostationary orbit, ~ 5 km resolution (IR) • Polar orbit, 500 km swath, 1 km resolution, high accuracy & stability (IR) • Natural ocean – atmosphere variability • Diurnal variability of SST • Clouds • Atmospheric aerosol • Sea ice etc. • Different SST product formatting Medspiration 4th and Globcolour 1st UCM

  6. Temperatures at all depths collapse overnight to the same value at dawn Thermal structure of top 5m (from sub-skin to 5m) The temperature at dawn (uniform through the top 5 m) is called the Foundation Temp. (SSTfnd) Temperature (oC) Arabian Sea WHOI Mooring Data - Spring 1995 (1mm data estimated using Fairall et al. (1996)) (From the PhD of A. Stuart-Menteth Medspiration 4th and Globcolour 1st UCM

  8. The GHRSST solution • Pre-process all L2SST datasets from different sources • Add error statistics if not already present • Add quality flags if not present • Attach ancillary data that can inform the interpretation • E.g., wind speed, solar radiation, atmospheric aerosol, sea ice • Re package as level 2P in standard (netCDF) format • Do this in near-real time • Create match-up database (MDB) • Pair all available in situ obs. of SST with coincident satellite data • Create a high resolution diagnostic dataset (HR-DDS) • Assemble extracts of all L2P data at specific sites for ease of intercomparison • Perform O.I. analyses of L2P data to create L4 products • Provide archive / distribution suitable for operational users • Oversee quality assessment and reanalysis Medspiration 4th and Globcolour 1st UCM

  9. Medspiration Data processing tasks Medspiration 4th and Globcolour 1st UCM

  10. L2 SST data from several sensors Auxiliary data (wind, etc.) CMS Sensor specific error statistics Ingest input and apply quality control Reference data fields In situ SST data Generate L2P data products Generate analysed SST L4 products Generate MDB records L2P data IFREMER MDB records Medspiration Final Archive L4 SSTfnd UHR Disseminate L2P data to GHRSST-PP GDAC & users Disseminate L4 UHR data to EU users NOCS Extract DDS L2P granules Extract DDS L4 granules GHRSST MDB Archive Medspiration DDS Archive L4 DDS UHR granules L2P DDS granules Disseminate DDS granules Distributed data processing chain for Medspiration Phase 1 Medspiration 4th and Globcolour 1st UCM

  11. Medspiration Coverage of L2P products Medspiration 4th and Globcolour 1st UCM

  12. The Medspiration UHR L4 product Ultra-high resolution (UHR) 2 km grid Analysis performed once per day Estimates the foundation SST Medspiration 4th and Globcolour 1st UCM

  13. Medspiration Phase 2 • Operational delivery of products from 1st June 2005 • Extended by at least 18 months in response to User request • The same range of products as developed in Phase 1 • UHR L4 domain extended west into Atlantic • Extended AATSR L2P product to global coverage • In response to the international users through the GHRSST ST • Provided since Dec 2005 • Developed a number of key operational users • Assimilation into ocean models • Met Office, UK FOAM model • Analysis products • OSTIA • Mersea • Scandinavian seas • Growing international use • See later talks from users Medspiration 4th and Globcolour 1st UCM

  14. Present status • Medspiration is operating as planned • See presentation by Jean-Francois Piollé, Operations manager • Regular delivery of the basic L2P products • MDB being generated • Being used to check error statistics • HR-DDS now has a web interface • Consulted by operational users • L4 products routinely generated • Configuration has been refined • Delivery time changed • Analysis now runs at 12.00 on Day N (delivery by 15:00) using data acquired between 06:00 on day N-1 and 06:00 on day N Medspiration 4th and Globcolour 1st UCM

  15. Current ongoing Development • Improved interface to MDB (CCN-1): Ifremer • Now in place and being used • Improved outreach tools (CCN-1): Boost Technologies • Medspiration products within Google Earth • See Fabrice Collard’s talk • Medea outreach along European coastline • E.G German newspapers used the UHR-L4 product during the recent summer • A study of methods for reaching the news media, and a eview of their interst is being made by Boost technologies • See Fabrice Collard’s talk • Improving the AATSR Error Statistics (CCN-2 recently approved) • Use of the MDB by AATSR validation scientist to improve SSES • Confirm the proposed use of the “view difference” data • See talk by Gary Corlett • Target is to establish a means for automatically checking SSES validity Medspiration 4th and Globcolour 1st UCM

  16. Sustaining the Medspiration Service • GMES Marine Core Services • Medspiration experience valuable for MCS implementation • GHRSST & Medspiration underpin the Sentinel-3 SST planning • Proposals for transitioning the Medspiration service into an element of the MCS • See presentation on Wednesday • Needs comments and endorsement of the user community • Timing of MCS implementation uncertain: Extension of Medspiration to Dec 2007 is desirable • Interaction – complementarity with GlobCOLOUR • Interchange of ideas and information is already occurring • Other mutual benefits to be explored at this meeting • The Importance of Medspiration’s users • You continue to be the drivers – tell us what you need • The same principle is to be applied within EU MCS activities Medspiration 4th and Globcolour 1st UCM
