    • Project drivers and objectives

    • Development approach & schedule overview

    • U-MARF technical overview


U marf project drivers and objectives

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)


U marf development approach

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


U marf schedule overview

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 developmentPlanned December 2001

    • End of integration with GS Planned May 2002

    • V2 Industrial development kick-off Planned January 2002

    • End of V2 developmentPlanned 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)

Performances issues

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


U marf archive ingestion and accumulation

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


U marf technical overview 3 3 summary

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
