The results obtained
from SIMDAT, a European research and development project,
are increasingly in demand from European and international meteorological
services and are likely to become acknowledged worldwide.
SIMDAT Meteo is working to establish a Virtual Global Information
System Centre (VGISC) for the national meteorological services
of France, Germany and the United Kingdom based on grid technology
to be used within the World Meteorological Organization Information
System (WIS) to provide cost-effective and user-friendly services.
VGISC offers a unique meteorological database integrating a
variety of data and providing secure, reliable and convenient
access via the Internet. It is targeted toward operational
services and research in the domains of meteorology, hydrology
and the environment.
The VGISC software developed
by the SIMDAT Meteo project partners, led by the European
Centre for Medium-Range Weather Forecasts, will offer meteorological
communities worldwide immediate, secure and convenient access
to various data and analysis services, as well as a user-friendly
platform for storage of meteorological data. VGISC will thus
enable the fast exchange of data for numerical weather forecasts, disaster
management and research -- independent of national frontiers and
beyond organizational boundaries.
The infrastructure of
this new system will be based on a mesh network of peers
and meteorological databases. Messages are interchanged using algorithms
based on mobile telephony technologies and metadata synchronization
on a journalized file system. The grid technology is based
on Open Grid Services Architecture Data Access and Integration (OGSA-DAI),
which is founded on Web service and Web technology concepts.
In addition, standard protocols such as Open Archive Initiative
(OAI) are used to synchronize and integrate existing archives
and databases, as well as to extend interoperability.
Furthermore, VGISC will be a test bed for the ISO 19115 metadata standard
by handling complex data in real-time.
The SIMDAT project is
Europe’s contribution to the infrastructure technology
of the emerging WIS as the World Meteorological Organization
(WMO) modernizes and enhances its long-standing Global
Telecommunications System (GTS), an international network
for exchanging mainly meteorological data and warnings in real-time.
In addition, the new system will provide access for all environmental
communities worldwide whereas GTS only allows access for
the present national weather services of the member states.
The opportunities for
the new VGISC technology are excellent as VGISC is not
only of interest within Europe: The national meteorological services
of Australia, China, Japan, Korea and the Russian Federation’s
National Oceanographic Centre have already deployed the
SIMDAT software and are collaborating actively with the European partners.
The software deployment is followed by an increasing number of
meteorological centers and new meteorological datasets from Asia, Australia,
Europe and the United States are steadily being added to the
