  3. Reminder - Objectives forR&D • Main objectives of R&D activities over 3 years : • Improvement of inter-sensor bias correction schemes • Improvement of error co-variances used in SST analysis schemes • Improvement of SST climatologies • SST analysis in Arctic Ocean Marginal Ice Zone • Necessary R&D activities for SST TAC new products (OSTIA re-analysis, higher resolution regional SST analyses) • Main issues : • Little resources dedicated to R&D (low ratio imposed during the proposal preparation) • MyOcean R&D call : no possibility for funding R&D activities outside the MyOcean Consortium

  4. R&D : main achievements • Main achievements for the 2nd year : • OSTIA re-analysis : final tuning of the OSTIA re-analysis chain before extensive re-processing : improved sea ice masking of PATHFINDER AVHRR data, improved smoothness in time, bias correction of ATSR-1 data against in-situ observations (MetO) • HR and UHR SST analyses in Med Sea : development of an improved bias correction and data merging scheme, and validation of the new scheme over year 2008 (CNR) • Main difficulty : • DMI/M-F proposal on inter-sensor bias correction to the first MyOcean R&D call finally not endorsed by SAC • Remaining activities/objectives • Improvement of SST climatologies : will be derived from OSTIA re-analysis (MetO)

  5. Reminder - Objectives forDev. & Maintenance • Main objectives over 3 years : • From V0 to V1, main objectives are : • Operational consolidation of processing systems in place • Interfacing with MyOcean system (Service Desk, MIS etc…) • Implementation of KPIs for SST TAC production • Definition and implementation of NRT quality control and validation tools for SST TAC • Implementation of the OSTIA re-analysis chain • From V1 to V2, products upgrades (higher resolution SST analyses over Baltic Sea and Arctic Ocean) • Main issue : • too short time between the availability of specifications for V1 (T0 + 5) and the V1 operational qualification (T0 + 18)

  6. Dev. & Maint. : main achievements • Main achievements for the 2nd year : • Implementation, configuration and testing of the THREDDS server and MIS gateway in SST TAC Dissemination Units (IFR, CNR and MetO) • Consolidation of operational production line for Arctic SST analysis (Met.no) • Development of new operational production line for global ODYSSEA SST analysis (IFR) • Main difficulties : • Lack of progress of HR-DDS (NOCS) • Lack of information for THREDDS server configuration and MIS gateway installation • Very tight schedule for V1 integration and testing • Remaining tasks : • Upgrades for V2 (including evolution towards GDS V2)

  7. Reminder - Objectives forProduction • Production architecture : • SST TAC production distributed over 6 Production Units • A 7th unit running a central quality monitoring and validation tool (HR-DDS at NOCS) • SST TAC products from 4 Production Units disseminated by IFR • 2 other Dissemination Units : MetO (OSTIA, GMPE), CNR (Med Sea and Black Sea products) • Almost all production lines already in place (but at various operational levels), key issue for V1 is their integration into the MyOcean system • Main issue : • Not enough resources for extensive reprocessing of all SST TAC products

  8. Production : main achievements • Main achievements for the 2nd year : • All committed SST TAC near real-time products produced and made available operationally for V1 Stream 1(except global ODYSSEA SST analysis) • All SST TAC Dissemination Units interfaced with the MyOcean system • Global OSTIA SST re-analysis (1985 – 2007) produced and made available (MetO) • Main difficulties : • Start of global ODYSSEA SST analysis operational production delayed (IFR) • Remaining objectives : • Operational production of remaining committed products for V1 (global ODYSSEA SST analysis) • Improvement of incident/problem management in SST TAC

  9. Reminder - Objectives forCal / Val • Main objectives over 3 years : • Quality control of input satellite data sources (L2P) based on match-up data bases (in-situ) made available in NRT by IFR and monitored continuously by M-F • First quality control step in NRT by each production unit for its products (L3/L4) • All SST TAC NRT products fed into the HR-DDS at NOCS, which can generate alarm messages to production units • Use of GMPE for quality control and validation of global SST analyses (MetO) • Main issue : • Definition of common validation areas and metrics with the MFCs

  10. Cal/Val : main achievements • Main achievements for the 2nd year : • Collection/production of match-up data bases for most of the input L2P SST TAC products in a standardized format (IFR) • Implementation of consistent products validation and quality monitoring schemes in all SST Production Units • Main difficulties : • Lack of progress of HR-DDS (NOCS) • Remaining tasks : • Full exploitation of match-up data bases for continuous quality monitoring of input L2P SST products (M-F)

  11. MainChallenges • Scientific Challenge : • Strong interaction needed to understand and define which is the “best” satellite SST product for data assimilation in each MFC (we didn’t achieve this in MERSEA) • Technical Challenge : • Schedule for V1 getting more and more challenging (detailed interface specifications between production/dissemination units and central sub-systems not yet frozen) • Operational Challenges : • Strong dependence on multiple input satellite data sources (SST L2P producers) • Single point of failure : AATSR SST L2P products (currently no satellite alternative for bias correction)

  12. FutureChallenges • Scientific Challenges • None • Technical Challenges • None • Operational Challenges • Management of SST TAC transition from V1 to V2 (SST TAC products format change), and of its impact on users • Ultimate Challenges • Having and keeping people with the right expertise in the right job in the long term • Main Risks • Disappoint users

  13. Calendar • Past : • December 2010 : SST TAC near real-time products part of MyOcean V1 Stream1 • End 2010 : end of global OSTIA SST re-analysis production (1985 – 2007) • Future : • June 2011 : global ODYSSEA SST analysis part of MyOcean V1 Stream2 • End 2011 / early 2012 : SST TAC production compliant with GDS V2

  14. 1st reporting period : Budget ~ 2 mn • Figures will be provided by PMO as soon as your partners have finished reporting and will be added to your presentation. • Be ready to give short explanations on main deviances during your presentation... • We are talking about estimated budget (best estimates) !
