  3. Purposes of WMO • To promote and foster meteorology, hydrology, and related geophysical sciences and to facilitate world-wide cooperation for the benefit of humankind: • Networks for meteorological / hydrological and other geophysical observations; • Standardization of observations and publications; • Development of operational hydrology; • Systems for processing and rapid exchange of data; • Applications for socio-economic development (transportation, water, agriculture, oceans, pollution control, etc), environment protection, and policy formation; • Disaster prevention and mitigation; • Research and training. APSDEU-7 Honolulu, Hawaii, 20-22 September 2006

  4. Organizational Structure • Congress, supreme body, determines the future policy (meets every 4 years) • Executive Council, 36 Directors of Meteorological or Hydrometeorological Services. They act in their individual capacities (meets annually) • Regional Associations (6) - Address regional concerns • Technical Commissions (8) - Technical experts make recommendations on scientific or technical issues within the purposes of WMO • Secretariat with Regional (3) and subregional (4) Offices APSDEU-7 Honolulu, Hawaii, 20-22 September 2006

  8. WMO Space Programme • Fourteenth WMO Congress (May 2003): • Recognized critical and fast growing importance of data, products and services provided by WWW’s expanding space-based component of the GOS to WMO Programmes and supported Programmes • Decided to initiate a new major WMO Space Programme as a cross-cutting programme to increase the effectiveness and contributions from satellite systems • Director of the WMO Space Programme is Dr Donald Hinsman APSDEU-7 Honolulu, Hawaii, 20-22 September 2006

  9. International coordination • CGMS (Coordination Group for Meteorological Satellites) • CEOS (Committee on Earth Observation Satellites) • IGOS (Integrated Global Observing Strategy) Partnership • COPUOS (UNISPACE III) • GEO and its GEOSS (WWW’s space-based GOS, a major GEOSS component) APSDEU-7 Honolulu, Hawaii, 20-22 September 2006

  10. WMO Space Programme - Activities • Co-ordination with space agencies within CGMS and CEOS • Organisation for new WMO Expert Team on Satellite Systems • Development of WMO portions of 10-year Implementation Plan for GEOSS • Interaction with the WMO Expert Team on the Evolution of the GOS • Preparation for symposia to identify R&D satellite data and products for transition to operational satellites • Continuation and expansion of the Virtual Laboratory for Education and Training in Satellite Meteorology • APSATS – HPTE 16-27 October 2006, Hosted ABoM Melbourne • Improving access to real-time satellite data, and increasing its utilisation [mainly via the Integrated Global Data Dissemination System (IGDDS)] APSDEU-7 Honolulu, Hawaii, 20-22 September 2006

  13. WMO Space Programme - IGDDS • IGDDS architecture generally consistent with what already exists • In addition provides approaches/guidance for: • Improving access to real-time data • Improving utilisation of real-time data APSDEU-7 Honolulu, Hawaii, 20-22 September 2006

  14. WMO Space Programme - IGDDS • Improving Access to Real-time Data • Match data reception arrangements to the needs of the various user communities • Utilise cheap, reliable, off-the-shelf user stations/reception mechanisms • Try to ensure only one data reception mechanism is required in order to meet the needs of a particular user community (“one-stop-shop” approach) • Facilitate data exchange between regions APSDEU-7 Honolulu, Hawaii, 20-22 September 2006

  15. WMO Space Programme - IGDDS • Improving Real-time Data Utilisation • Facilitate the creation of appropriate regional collection networks that match user requirements • Ensure that data exchanged between regions satisfies certain standards, e.g.: • Product level • Product format • Processing software utilisation • Improve timeliness (where appropriate) • Improve data reliability/availability through the adoption of minimum operational standards for the generation of products exchanged between regions (e.g. service monitoring, redundancy etc.) APSDEU-7 Honolulu, Hawaii, 20-22 September 2006

  16. WMO SP: IGDDS in Action - RARS • EUMETSAT ATOVS Retransmission Service (EARS) has increased ATOVS real time access in Northern Hemisphere • Access to near real time ATOVS data important for WMO activities such as implementation planning for the redesign (evolution) of the GOS and THORPEX • Need to extend coverage globally especially Southern Hemisphere • Regional ATOVS Retransmission System [RARS]: • Following requests from the user community the WMO arranged the 1st RARS workshop (Darmstadt, December 2004) with a number of objectives • To consolidate the requirements for ATOVS data around the globe • To define a global RARS network capable of meeting these requirements • To facilitate the implementation of a global RARS network • need for two additional RARS was identified: • Asia-Pacific RARS • South American RARS • ensure consistency of the global RARS dataset via standards in the following areas : • Use same version of AAPP S/W for data exchange between the regions (plus BUFR format conversion) • Quality-tagging of data (for source traceability) • Service management (e.g. service monitoring) • WMO Space Programme coordinates & facilitates global RARS activities (Regional ATOVS Retransmission Services) similar to EARS (part of its core strategy to increase satellite data use) • RARS-2 1-2 Dec 2005; SthAmer RARS 6-7 September 2005; RARS-3 31 Aug-1Sept 2006.

  19. Outcome of the 3rd global IGDDS-RARS Workshop31 August– 1 September 2006

  20. 3rd global RARS & IGDDS workshop • Participants from : • Australia, China, Japan, Korea (Asia-Pacific RARS) • EUMETSAT and NOAA (EARS) • Brazil & Argentina (South-American RARS) • WMO Secretariat (WMO SP and WWW/ISS) • GEO (Geonetcast and GEO secretariat) • Agenda: • Overall IGDDS project • RARS status and plans • ADM status and plans APSDEU-7 Honolulu, Hawaii, 20-22 September 2006

  21. General outcome • IGDDS Implementation plan reviewed,action plan was detailed focus on RARS and ADM projects • Asia-Pacific RARS is starting • South-America RARS is new priority • ADM plans need to be finalised in Asia and America APSDEU-7 Honolulu, Hawaii, 20-22 September 2006

  22. EUMETCast Update • Experience with EUMETCast has shown the importance of “scalability” in terms of dissemination bandwidth • EUMETCast started out as a very limited service (for re-transmitting ATOVS data) in 2002 with a bandwidth of 128Kbps • Driven by user requests, EUMETCast has now become the primary dissemination mechanism for satellite data over Europe [includes MSG-1 (Meteosat-8), Meteosat-5, Meteosat-6 (rapid scans), GOES, AVHRR and ATOVS data]. Bandwidth in 2005 was 3.7Mbps, now 12 Mbps • Key factors in the success of EUMETCast: • Cheap, reliable, off-the-shelf user reception stations (<$2000 including PC) • Ku-band over Europe (85cm) • C-band over Africa (2.4m) • Data consolidated onto one dissemination mechanism  “one-stop-shop” approach APSDEU-7 Honolulu, Hawaii, 20-22 September 2006
