14 APSDEU-7 Honolulu, Hawaii, September 2006 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

15 APSDEU-7 Honolulu, Hawaii, September 2006 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

16 APSDEU-7 Honolulu, Hawaii, September 2006 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.)

17 APSDEU-7 Honolulu, Hawaii, September 2006 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 Dec 2005; SthAmer RARS 6-7 September 2005; RARS-3 31 Aug-1Sept 2006.

23 APSDEU-7 Honolulu, Hawaii, September 2006 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
