Enhancing Meteorological Data Sharing through the SIMDAT Project

The SIMDAT project, in collaboration with the World Meteorological Organization (WMO), aims to improve meteorological data sharing and integration. By establishing a global infrastructure for real-time data access, SIMDAT enhances weather prediction and operational meteorology. With participation from key national meteorological centers, EUMETSAT, and ECMWF, the project focuses on developing scalable, interoperable systems for data synchronization and discovery. The initiative has achieved significant milestones in connectivity and knowledge sharing, ensuring accessible weather data worldwide.

  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
