1 Villefranche sur Mer: 4th-6th Dec 2006 Medspiration 4th and Globcolour 1st UCM Overview of Progress in Medspiration Ian Robinson, Project manager

2 2Villefranche sur Mer: 4th-6th Dec 2006Medspiration 4th and Globcolour 1st UCM Outline of Medspiration Project Status Background to the Medspiration Project Overview of the Medspiration Service Summary of Operation Recent Developments Looking forward

3 3Villefranche sur Mer: 4th-6th Dec 2006Medspiration 4th and Globcolour 1st UCM A brief history of Medspiration 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 Contract confirmed Dec K/O Phase 1 of Medspiration System Requirements Review: 4-5 Mar, 2004 Critical design review: 14 th July, 2004 Qualification Review: Nov, 2004 Beta Test: 1-28 Feb 2005 Acceptance Review & 1 st UCM : March 2005 Medspiration Consortium National Oceanography Centre, Southampton (Prime) Ifremer, Brest Meteo-France (CMS, Lannion) CLS, Toulouse CNR, Rome Met.No, Oslo Vega plc, UK

4 4Villefranche sur Mer: 4th-6th Dec 2006Medspiration 4th and Globcolour 1st UCM 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. Data Fusion Quality Control User Applications To facilitate the movement of data

5 5Villefranche sur Mer: 4th-6th Dec 2006Medspiration 4th and Globcolour 1st UCM 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

6 6Villefranche sur Mer: 4th-6th Dec 2006Medspiration 4th and Globcolour 1st UCM Temperature ( o C) Arabian Sea WHOI Mooring Data - Spring 1995 (1mm data estimated using Fairall et al. (1996)) Thermal structure of top 5m (from sub-skin to 5m) (From the PhD of A. Stuart-Menteth Temperatures at all depths collapse overnight to the same value at dawn The temperature at dawn (uniform through the top 5 m) is called the Foundation Temp. (SST fnd )

7 7Villefranche sur Mer: 4th-6th Dec 2006Medspiration 4th and Globcolour 1st UCM Near-surface profiles of temperature A ship intake measures SST about here A buoy measures SST about here Infrared radiometers measure skin SST Foundation SST Microwave radiometers measure sub-skin SST

8 8Villefranche sur Mer: 4th-6th Dec 2006Medspiration 4th and Globcolour 1st UCM 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

9 9Villefranche sur Mer: 4th-6th Dec 2006Medspiration 4th and Globcolour 1st UCM Medspiration Data processing tasks

10 10Villefranche sur Mer: 4th-6th Dec 2006Medspiration 4th and Globcolour 1st UCM Ingest input and apply quality control L2 SST data from several sensors In situ SST data Auxiliary data (wind, etc.) Generate L2P data products Generate MDB records Generate analysed SST L4 products Disseminate L4 UHR data to EU users L2P data L4 SSTfnd UHR Disseminate L2P data to GHRSST- PP GDAC & users Extract DDS L2P granules Sensor specific error statistics Reference data fields Extract DDS L4 granules L2P DDS granules L4 DDS UHR granules Medspiration Final Archive MDB records Medspiration DDS Archive GHRSST MDB Archive CMS IFREMER NOCS Disseminate DDS granules Distributed data processing chain for Medspiration Phase 1

11 11Villefranche sur Mer: 4th-6th Dec 2006Medspiration 4th and Globcolour 1st UCM Medspiration Coverage of L2P products

12 12Villefranche sur Mer: 4th-6th Dec 2006Medspiration 4th and Globcolour 1st UCM The Medspiration UHR L4 product Ultra-high resolution (UHR) 2 km grid Analysis performed once per day Estimates the foundation SST

13 13Villefranche sur Mer: 4th-6th Dec 2006Medspiration 4th and Globcolour 1st UCM Medspiration Phase 2 Operational delivery of products from 1 st 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

14 14Villefranche sur Mer: 4th-6th Dec 2006Medspiration 4th and Globcolour 1st UCM 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 on Day N (delivery by 15:00) using data acquired between 06:00 on day N-1 and 06:00 on day N

15 15Villefranche sur Mer: 4th-6th Dec 2006Medspiration 4th and Globcolour 1st UCM 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 Collards 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 Collards 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

16 16Villefranche sur Mer: 4th-6th Dec 2006Medspiration 4th and Globcolour 1st UCM 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 Medspirations users You continue to be the drivers – tell us what you need The same principle is to be applied within EU MCS activities
