Lothar.Wolf@eumetsat.int WMO RA VI WORKSHOP, SOFIA, BULGARIA, 1 – 3 NOVEMBER 2011 Slide: 3 Advantages for a Relevant Data Centre to Participate in WIS as a DCPC The data and information used or produced by a WIS DCPC can be more easily shared with data and information supported by other systems, resulting in improved products and services, or new cross-system discoveries. The association of related systems through WIS enables collective optimization of observational strategies and cooperative gap filling, leading to coverage and continuity improvements for observations. Participating in WIS enhances the potential for cost-sharing for data collection, processing, distribution, archiving, and other expenses. A centre designated as a WIS DCPC heightens the profile of the center without compromising its own identity, gaining worldwide exposure to potential users of the products and services offered. A centre designated as a WIS DCPC gains worldwide prospects for collaborations that enhance products, services, or performance. Association with WIS enables the centre to draw on world-class expertise in Weather, Climate, and Water observations, modeling, and automated systems. Centres implementing WIS enhance their interoperability through international standards that in turn could be implemented at other levels within the organization and with its partners. A centre designated as a WIS DCPC gains opportunities to cooperate in capacity-building efforts to enhance contribution and use of information services, often an underserved objective of data centres.
Lothar.Wolf@eumetsat.int WMO RA VI WORKSHOP, SOFIA, BULGARIA, 1 – 3 NOVEMBER 2011 Slide: 4 EUMETSAT DCPC EUMETSAT DCPC implementation: Making use of the existing EUMETSAT operational systems with small enhancements and integrating them into WIS infrastructure. What are EUMETSAT DCPC functions: EUMETSATs mission is to collect operational satellite data and non-satellite data (like forecast), produce meteorological products and deliver data and products that satisfy the meteorological and climate data requirements of its Member States. EUMETSAT offers: -Real-time functions of data and product dissemination via its EUMETCast system, Direct Dissemination from some of its satellites and via GTS/RMDCN. -Non real-time services for requests via its Date Centre that provides offline access to EUMETSAT archive, and via its Internet pages. -Provision of relevant up-to-date metadata catalogues via EUMETSAT Earth Observation Portal (Product Navigator) -Coordination and synchronization functions with the associated GISC via GTS/RMDCN and EO Portal. -Adherence to WIS standards and relevant data exchange policies and access rights (via EO Portal).
Lothar.Wolf@eumetsat.int WMO RA VI WORKSHOP, SOFIA, BULGARIA, 1 – 3 NOVEMBER 2011 Slide: 5 Data Collection and Data Production intended for Dissemination Within its area of responsibilities EUMETSAT collects operational satellite data and non-satellite data, produces meteorological products and delivers data and products that satisfy the meteorological requirements of its Member States. Within the framework of WMO Programs As a key member of the WMO Global Observing Systems (GOS), EUMETSAT is actively contributing through the provision of data, products and services from its satellites. Within the framework of CGMS EUMETSAT is actively encouraging other satellite operators to implement the relevant interfaces and make satellite data available in WIS
Lothar.Wolf@eumetsat.int WMO RA VI WORKSHOP, SOFIA, BULGARIA, 1 – 3 NOVEMBER 2011 Slide: 6 Information Provision Intended for Global and non-Global Exchange EUMETSAT is responsible for provision of real-time functions of data and product dissemination Via Direct Dissemination and EUMETCast, its satellite dissemination systems Via GTS/RMDCN Via bi-lateral data exchange links to strategic partners EUMETSAT is also disseminating data and metadata world-wide through GEONETCast a near real time, global network of satellite-based data dissemination systems. GEONETCast is a contribution to WMO- IGDDS.
Lothar.Wolf@eumetsat.int WMO RA VI WORKSHOP, SOFIA, BULGARIA, 1 – 3 NOVEMBER 2011 Slide: 7 Provide Access to Information The Earth Observation Product Navigator is the EUMETSAT centralised discovery service facilitating access to all EUMETSAT data and products. It is a web based interface available via Internet providing access to the EUMETSAT DAR catalogue. Users can find their data using a simple full-text search, a geographic and time search or using a browse by theme mode. The Product Navigator provides a secure access to all real-time or offline archived EUMETSAT datasets. The product navigator is available from: http://www.eumetsat.int/Home/Main/DataProducts/ ProductNavigator/index.htm Use of International Metadata Standards to be interoperable The Product Navigator is a fully interoperable information discovery system: It is built upon ISO 19115/19139 XML Metadata standards. All Metadata records are also conforming to the EU INSPIRE directive. It provides search and discovery APIs compliant to the Open Geospatial Consortium Services for Web 2.0.2 (OGC CSW) standard as well as ISO 23950 SRU protocol.
Lothar.Wolf@eumetsat.int WMO RA VI WORKSHOP, SOFIA, BULGARIA, 1 – 3 NOVEMBER 2011 Slide: 8 Real-time Interconnection to GISCs to be part of the WIS As a DCPC, EUMETSAT is providing data intended for global and regional exchange to the designated GISCs in its WMO region. EUMETSAT also has in place operational procedures for synchronizing its metadata catalogue with the GISC Offenbach. EUMETSAT Metadata contained within the Product Navigator is operationally synchronised to GISC Offenbach in WMO core profile 1.2. GISC Offenbach is synchronizing its product catalogue with other GISCs such as GISC Beijing and via the network of GISCs, EUMETSAT datasets can therefore be discovered and retrieved from anywhere within the WIS. As soon as the OpenWis software platform has been declared operational by the consortium, EUMETSAT will also interface itself with the GISCs Toulouse and Exeter.
Lothar.Wolf@eumetsat.int WMO RA VI WORKSHOP, SOFIA, BULGARIA, 1 – 3 NOVEMBER 2011 Slide: 9 WIS Key Benefits for users of EUMETSAT data and products With the WIS, exposure and availability of EUMETSAT products and datasets are greatly increased as they can now reach potential users that are not necessarily part of the meteorological community. The EUMETSAT DCPC infrastructure is operationally ready to function as DCPC in WIS and welcome all WIS users that want to take advantage of the EUMETSAT datasets IN 2010 EUMETSAT ENROLLED AS A DATA COLLECTION OR PRODUCT CENTRE (DCPC) AND WAS SUCESSFULLY ENDORSED AS DCPC by CBS-ext 2010 and XVI WMO Congress.
