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

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
