  6. Space-based Global Observing System • operational meteorological LEO satellites • Baseline = 4 sat (2 am + 2 pm) + contingency • Optimized orbital planes for efficient temporal sampling • operational meteorological GEO satellites • Baseline = 6 sat + contingency • Optimized equatorial locations for efficient coverage • Research and Development satellites • declared by operators as contributing to the GOS • Operational inter-calibration system (GSICS) (In future) North-America-Europe Data Exchange, 3-5 May 2006

  7. WWW’s space-based component of the Global Observing System (2006) Unparalleled international cooperation has been achieved in satellite activities North-America-Europe Data Exchange, 3-5 May 2006

  8. Distribution of planned sensors in Low Earth Orbit North-America-Europe Data Exchange, 3-5 May 2006

  9. Scope of the GOS • Towards a WMO Integrated Global Observing System (WIGOS) covering the needs of all WMO programs: • 3 Earth-system domains (atmosphere, ocean, land) • and 2 cross-cutting themes (climate, disasters) • WIGOS to become a major contributor to GEOSS North-America-Europe Data Exchange, 3-5 May 2006

  11. ACRONYMS • IGDDS: Integrated Global Data Dissemination Service • ADM: Advanced Dissemination Methods - routine broadcast (push) - normally via commercial telecom satellite - following current standard (DVB-S, IP) • RARS: Regional ATOVS Retransmission Service(e.g. EARS) • WIS : (future) WMO Information System North-America-Europe Data Exchange, 3-5 May 2006

  12. Logarithmic scale ! IGDDS Background North-America-Europe Data Exchange, 3-5 May 2006

  13. IGDDS Definition and baseline • IGDDS : satellite data & products circulation scheme • to meet the needs of WMO Programmes for improved access • as agreed in WMO Space Programme Implementation Plan • IGDDS Baseline • Integrates all satellite-related data fluxes • Global exchange of satellite data among regional centres • Dissemination relying on ADM and Direct Broadcast • ADM mainly via Digital Video Broadcast by telecom satellite • cost-efficient for end-users and for operators • fully integrated within the WMO Information System (WIS) but identified end-to-end service for space-based data North-America-Europe Data Exchange, 3-5 May 2006

  14.

All kinds of WMO programmes data & products (mostly non-satellite) Data Collection & Product Centres Data Collection & Product Centres Data from operational Polar and Geostationary satellites available within region Other regional data :R&D, high-level products National Centres Inter-operability Global Information System Centre (Satellite) Data Collection & Product Centre and data exchange Data Dissemination (possibly shared with non-satellite) Other data-communication means Other data communication means ADM #2 ADM #1 User Community #1 User Community #2 Users IGDDS definition and baselineIGDDSwithin WIS in each region IGDDS components North-America-Europe Data Exchange, 3-5 May 2006

  16. Data acquisition activities:RARS for timely access to polar data Regional ATOVS Retransmission Services (RARS) complement the baseline ground segments of polar satellites: Data acquired by several local receiving stations are concentrated, processed and redistributed for regional and global NWP users Timeliness= 30 minutes instead of 2-3 hours for global data. • EARS (Eumetsat) covers Europe, N-America and North Pole • expanding to include new data (AVHRR, ASCAT from METOP) • distribution via GTS and DVB-satellite broadcast • Plan for Asia-Pacific RARS (distribution via GTS and Internet/FTP) • Plan for South-America RARS (distribution via GTS and Internet/FTP) North-America-Europe Data Exchange, 3-5 May 2006

  17. Data acquisition activities: North-America-Europe Data Exchange, 3-5 May 2006

  18. Data dissemination activitiesIGDDS dissemination approach Dissemination concept reviewed at ET-SUP, CGMS, RARS-ADM workshop, and reported at CM-6 (Jan. 2006) • Global ADM coverage possible with at least 4 “regional” dissemination services • to be established by satellite operatorsor consortia including satellite operators • critical need for Asia-Pacific region • Sat operators to take responsibility for ADM dissemination services over regions consistent with the location of their primary users (e.g. footprint of their GEO satellites ) • Target date : January 2007 North-America-Europe Data Exchange, 3-5 May 2006

  19. Data disseminationactivitiesADMs by satellite operators • Europe : Eumetcast-Ku band (Eumetsat) • Africa and Caribbean: Eumetcast-C band • North-, Central & South-America : • pilot Eumetcast-C band for 2006-2008 • considerations for transition to a NOAA ADM by 2008 • Asia-Pacific regions : • current Shinetek ADM over China • trial planned in 2006 for wide Asia-Pacific ADM including DVB-S broadcast complemented by terrestrial links • Group on Earth Observation (GEO): • Eumetcast serving as a demo for GEOnetcast within GEOSS North-America-Europe Data Exchange, 3-5 May 2006

  20. Inter-regional data exchange • Growing need for near real-time access to global data sets • Evolving data requirements to be reviewed on regional basis • North America-Europe Data Exchange (NAEDE) and Asia Pacific Satellite Data Exchange and Utilization (APSDEU) are excellent models • Rolling Requirements Review mechanisms still to de discussed but NAEDE and APSDEU are expected to contribute to the process • Technical means for data exchange to be agreed by satellite operators • building on existing means if relevant • within WIS context • considering new requirements (e.g. adaptative observations ?) North-America-Europe Data Exchange, 3-5 May 2006

  21. Conclusion • North America Data Exchange meeting provides WMO SP observer with valuable opportunity for better awareness of status, plans and issues related to satellite data use by major NWP centres • The activity of this informal group is of high interest with respect to IGDDS objectives • Thank you !
