  4. U-MARF Project drivers and objectives • EUMETSAT decision in 1997 to develop a multi-mission, archiving and retrieval facility, including on-line web user access capability, supporting all EUMETSAT programmes: the Unified Meteorological Archive and Retrieval Facility “U-MARF” • Offer integrated user access to the whole of EUMETSAT data products and services: • GEO data : • Meteosat Transition Programme (MTP) (including historical archive from METEOSAT 1 to 6), • Meteosat Second Generation (MSG-1 to MSG-3) • LEO data : EUMETSAT Polar System (EPS) (METOP satellites), • Plus multi-mission products ( Level 2 and above) from Satellite Application Facilities (SAF) • Exploit and take advantage of new technologies (e.g. archiving, on-line web access) • Built in flexibility and scalability to accommodate future new data and archive growth potential • Objective is to provide access to a wide range of external users (from novice users, to expert meteorological and climate communities)

  5. U-MARF Development approach • U-MARF procured from industry : contract allocated to Consortium including Matra Systemes & Information (F) as Prime, with ACS (I) approved by EUMETSAT Council in November 1998 • Incremental development performed in two major versions: • U-MARF V1: • phased on MSG development schedule • providing common multi-mission functions and services for MSG and MTP data and products • MTP data to be migrated from current MARF to U-MARF in 3 years minimum • U-MARF V2 : • phased on EPS development schedule • extending services to EPS data sets and implementing connectivity with the SAF

  6. U-MARF Schedule Overview • U-MARF Development Milestones:: • Project start Early January 1998 • Invitation To Tender July 1998 • V1 Industrial development kick-off Mid-December 1998 • End of V1 development Planned December 2001 • End of integration with GS Planned May 2002 • V2 Industrial development kick-off Planned January 2002 • End of V2 development Planned March 2004 • U-MARF services milestones: • Ingestion, archiving and cataloguing MSG data: operational for MSG-1 launch • Standard user services : fully operational after end of MSG-1 commissioning • End of migration of MTP data: MSG-1 launch + 3 years (TBC)

  8. U-MARF Technical Overview (2/3) • U-MARF Functions: • Ingestion - Archiving & cataloguing chain: • Ingestion from Ground Segments (processing facilities), and Remote Centres • Archiving & Cataloguing • Retrieval - Ordering & Delivery chain : • User Services • Product Formatting and Delivery • Monitoring & Control & Administration: • Monitoring & Control • User administration • Excluded functions: • Processing, [Re-processing]

  9. Performances Issues • Data ingestion: • For V1: capacity to ingest 3 MSG data stream in parallel : 180 Gbytes/day - 2.4 Mbytes/s • For V2 :capacity to ingest 2.2 EPS data stream in parallel: 420 Gbytes/day - 5.5 Mbytes/s • User data retrieval : • For V1: 100 Gbytes/day • For V2: 600 Gbytes/day then 1.2 Tbytes/day • Capacity requirement: • see next • On-line user connections: • For V1: capacity to support at least 10 simultaneous users for on-line data retrieval for V1 • For V2: capacity to support at least 30 simultaneous users for on-line data retrieval • Availability of data for user retrieval • Data accessible to users 2 hours after ingestion into the U-MARF • SAF catalogue records accessible to users 3 hours after ingestion

  10. U-MARF Archive ingestion and accumulation • MTP: ~ 15 Terabytes/year => total of ~ 45 Terabytes • MSG: ~25 Terabytes/year => total of ~300 Terabytes • EPS: total of ~100 Terabytes/year => total of ~ 1.5 Petabytes

  11. U-MARF Technical Overview (3/3)Summary • Characteristics & constraints summary: • Technical features: • Near-real time ingestion constraints from processing facilities • Throughput performances: ingestion + retrieval • Operational aspects: • Drastic availability & reliability constraints: 10 minutes downtime • Automated archive and automated production for retrieval including for media delivery to users (small robots/stackers providing 48 autonomy of operations) • Open points: • Inter-operability features with other EO providers I.e. CEOS,… • User feedback on user services definition and performances

  12. 2. How can users gain access to U-MARF? • U-MARF standard services presentation : How can users gain access to U-MARF data? • U-MARF standard services overview • Access to U-MARF data: Product search (Inventory & Browse) and ordering • U-MARF distribution formats • User documents

  13. U-MARF standard User Services • U-MARF services will be integrated with EUMETSAT user services and accessed from the EUMETSAT home page (www.eumetsat.de) • U-MARF Core Services : • Information and Guide: aiming at providing users with general information and documents (about U-MARF, products characteristics, file formats, …) • Product search (Inventory and Browse): allowing users to search for archived products (simple or advanced queries) and to obtain information (metadata , thumbnails, browse images) on the selected products • Ordering and Follow-up: allowing users to order selected products (further to Inventory search services) • U-MARF Supporting Auxiliary Services: • User Registration : allowing a user to log-in as known user or to request for a registration (user account and user profile) • User Services Administration: users account management, EUM data policy implementation, invoicing management... • Help Desk: comprehensive help desk services supported by automated functions

  14. Access to U-MARF data: product search & ordering • Inventory search • V1/V2 search features => GEO and common search features: • Temporal search criteria • Metadata search criteria :satellite, instrument, product type, processing level, version of algorithm, quality indicators • V2 additional LEO specific features: orbit, geographical search • Ordering features: • Elementary orders (on archived products) or Standing Orders (subscription on future selected products in a pre-defined time range) • Product subsetting capabilities: • spectral bands subsetting • geographical subsetting (ROI for GEO image products, orbit subset for LEO orbit based products) • specific subsetting (header and/or trailer extraction) • Delivery options : • Electronic (ftp) • Physical media delivery : media includes : CD-ROM, [DVD], DAT, Exabyte, DLT • High quality printouts

  15. U-MARF Distribution Formats • U-MARF V1 Distribution Format: • Native format (as generated by MTP or MSG Ground Segment ) • Band Sequential Format for SEVIRI Level 1.5 • Open MTP for: • Level 1.0 and Level 1.5 • Cloud Analysis, Cloud Motion Winds, Sea Surface Temperature, Upper Tropospheric Humidity, Climate Data Set • WMO / BUFR for MTP MET Products and for the following MSG MET Products : • Atmospheric Motion Vectors (AMV), Cloud Analysis (CLA) , Clear Sky Radiance (CSR), Tropospheric Humidity (TH), Climate Data Set (CDS), Total Ozone (TOZ) • JPEG for METEOSAT and SEVIRI level 1.5 • Other Distribution Formats (TBD): including formats requested by last STG OPS WG :McIdas, and other evolutions of the MTP MARF • Additional U-MARF V2 Distribution Formats: • Native format (as generated by EPS Ground Segment ) • WMO formats (BUFR/GBRIB) for all EPS products • HDF (Hierarchical Data Format) for MTP, MSG and EPS products • PNG (Portable Network Graphics) for MTP, MSG and EPS products

  16. Conclusions • U-MARF is part of a EUMETSAT effort to : • build an affordable and maintainable multimission infrastructure by exploiting commonalty between the different programmes • Enhance user access to EUMETSAT data products and services, as they become relevant to a wider range of user communities
