Service contains: SYNOP, TEMP, PILOT, Warnings and Tropical Cyclone data: Forecast data in GRIB format from ECMWF and DWD: Charts of WAFS, Aerological Diagrams, basic meteorological field parameters and observations in graphical form. Access to BMD is restricted to the WMO members (National Meteorological Services and partner organisations) of the WMO Regional Association VI.

Slide: 19/30WMO TECO-WIS Seoul 07 Nov 2006 The Future -EUMETCast as service framework for current and pre- operational mission data delivery with guarantied timeliness -EUMETCast as technology core for the implementation of a satellite multicast based dissemination system for environmental data with global coverage: GEONETCast

Slide: 20/30WMO TECO-WIS Seoul 07 Nov 2006 GEONETCast Background -Ministers agreed at the third Earth Observation Summit in February 2005 to develop the GEOSS to meet the need for timely, quality, long-term global environmental information as a basis for sound decision making and to enhance delivery of the benefits to society. -GEONETCast is a dissemination system under development by which GEOSS environmental satellite and in situ data and products from participating Data Providers will be transmitted to users using a multicast, access controlled, broadband capability. -Especially useful for less developed or low infrastructure areas -Participation in GEONETCast as a data provider, end user, or dissemination infrastructure provider is voluntary. -The intergovernmental Group on Earth Observations (GEO) has defined the GEONETCast task as Capacity Building Task #CB with oversight by the GEO Architecture and Data Committee

Slide: 21/30WMO TECO-WIS Seoul 07 Nov 2006 GEONETCast Benefits -A key feature in increasing the use of environmental data globally is to make it accessible to all nations in a cost-effective and efficient manner. -Given the rapidly increasing volume and diversity of data and products, particularly from earth observation and environmental satellites, this presents a real challenge. Adding to the complexity of the situation is the diversity of organisations and national entities involved in earth observation satellite systems, in-situ observations and production activities. -The introduction of a coordinated, coherent, global dissemination scheme that addresses the existing problems of data dissemination is to be welcomed, and GEONETCast has the potential to achieve these goals in coordination with other data dissemination methods. -GEONETCast promises to facilitate and enhance access, particularly for developing countries, to key environmental data in the nine societal benefit areas of GEO.

Slide: 22/30WMO TECO-WIS Seoul 07 Nov 2006 GEONETCast Status EUMETCast, operated by EUMETSAT, currently provides the operational dissemination infrastructure that hosts GEONETCast. This provides geographic coverage of Europe, the Middle East, Africa, and South, Central and most of North America. Discussions have started with the Chinese Meteorological Administration (CMA) to integrate FengYungCast into GEONETCast. This would provide geographic coverage of the Asia/Pacific region. A first data exchange trial has been started and is demonstrated at CGMS in Shanghai. NOAA has a stated initial intention to establish a dissemination system providing comprehensive coverage of the Americas known as GEONETCast Americas. Users in the region will be provided with a long-term perspective for access to GEONETCast. A data exchange trial was established during summer including a local American beam demonstrated in Seattle. The GEONETCast concept was also presented during various GEO conferences and during this years EUMETSAT African User Conference (Maputo)

Slide: 23/30WMO TECO-WIS Seoul 07 Nov 2006 GEONETCast Status Together, these three regional systems (EUMETCast, FengYunCast and GEONETCast Americas) form GEONETCast, and have the capability to provide global coverage. AsiaS at-4 GEONETCast Evolution to global coverage

Slide: 24/30WMO TECO-WIS Seoul 07 Nov 2006 GEONETCast Status The added value that GEONETCast brings is to facilitate and enhance access, particularly for developing countries, to key environmental data in the nine societal benefit areas of GEO by applying standards across, and encouraging the development of, regional systems. These three regional systems are seen as the minimum required to establish global geographic coverage. Should additional regional systems be made available the GEONETCast concept can easily accommodate them.
