  1. SIMDAT Meteo Activity OGF23 2-6 June 2008 Barcelona Marta Gutierrez, Baudouin Raoult, Cristina Arciniegas ECMWF Marta.Gutierrez@ecmwf.int Simdat.info@ecmwf.int Simdat Project –GTD. Meteo Activity – 10.03.08

  2. SIMDAT Meteo and the WMO WIS activity • Main Drivers of the Meteo activity come from the World Meteorological Organisation WMO Information System (WIS): • WIS aims to implement a single, co-ordinated global infrastructure for the collection and sharing of information in support of all WMO and related international programmes. • Meteo Activity: Takes on board the WIS concept to develop infrastructure components that validate the benefits of the GRID/SOA technologies as stated by the SIMDAT project. • Meteo joins SIMDAT to solve the data centric problems posed from weather prediction and operational meteorological activities. • 5 Partners: 3 National Meteorological Centres (Germany DWD, Meteo-France, UK Met Office) EUMETSAT and ECMWF • Coordination and main developments for Meteo Activity: ECMWF Simdat Project –GTD. Meteo Activity – 10.03.08

  3. Real-time data flow: From Observation to Numerical Weather Prediction to Decision Making

  4. The Virtual Global Information System: VGISC Simdat Project –GTD. Meteo Activity – 10.03.08

  5. SIMDAT Meteo: 3 ½ Years of achievements • Phase I: Connectivity • Establishment of the first version of grid Infrastructure. • 5 Meteorological partners fully connected. • Main services: Data Access, Catalogue, Synchronisation, Discovery (1st version) • Phase II: Interoperability • Mature and stable grid infrastructure. • Distributed meteorological partners are on p2p network. (To address scalability requirements) • Synchronisation/data requests follow the p2p infrastructure. • Software reaches an international deployment with collaborators from Asia, Australia, US. • Phase III: knowledge Phase • Implemented Virtual Organisations (Security), Ontologies. • Subscription to real time data.

  6. Access to existing data repositories in a non-intrusive fashion • FTP • Relational DataBases • Archives • OpenDAP • OGC Web Map Server • GRIA

  7. A scalable system: addition of new sites

  8. Catalogue Synchronisation: each site has a copy of the global catalogue Synchronisation

  9. Data from anywhere can be accessed from everywhere Retrievals

  10. Sites are organised in a mesh network • Each site is connected to 2-3 peers at most • Catalogues are synchronised with neighbours • Each site can reach any sites which is part of the network • Data requests • Provides a scalable solution

  11. From architecture to usage

  12. Portal: Search

  13. Text Search: Fields

  14. Metadata: WMO Core Profile (from ISO19115)

  15. Request basket

  16. Portal: Multiple data types support

  17. Ontology enhancement to discovery Simdat Project –Meteo Activity – OGF23

  18. Security Implementation

  19. Subscription to Real Time data

  20. Status: 11 sites connected Satellite data Model output Climate Time Series Research datasets Oceanographic data ERA40 data TIGGE data Model output Observation More than 27,000 datasets discoverable Model output Real-time GTS data Climate Time Series Model output Satellite data Model output Wave Observation Aviation data (TAF, METAR) Lightning data
