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

2. 2 SIMDAT Simdat Project –GTD. Meteo Activity – 10.03.08 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

5. 5 SIMDAT 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 (1 st 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. 6 SIMDAT Access to existing data repositories in a non- intrusive fashion FTP Relational DataBases Archives OpenDAP OGC Web Map Server GRIA

7. 7 SIMDAT A scalable system: addition of new sites

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

9. 9 SIMDAT Data from anywhere can be accessed from everywhere Retrievals

10. 10 SIMDAT 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
