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 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.

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
