TRENDS IN INFORMATION TECHNOLOGY
The opportunity is to take these new technologies
and build a logically separate Future WMO
Information System (FWIS), using the Internet,
which meets the requirements of all WMO
programmes for the exchange of meteorological
and related data.

WMO Congress XIV (2003)
“The multiplicity of systems of the different Programmes
causes incompatibilities, inefficiencies, duplication of
efforts and higher overall costs.”
Congress approved the concept of FWIS, which will
provide a single coordinated global infrastructure for
the collection and sharing of information in support of all
WMO and related international programmes.

Cross-programme requirements for
FWIS
• Widely available and electronic (on-line) metadata and data
catalogues of all relevant data required by the WMO
Programmes
• Harmonisation of data formats, transmission standards,
archiving and distribution mechanisms to better support interdisciplinary use of data and products.
• Standard practices for the collection, electronic archival and
exchange of metadata, both high-level and detailed, especially
for stations and instruments.

Technical requirements
 Routine collection and automated dissemination of all
observed data and products (”push”) according to
requirements.
 Ad-hoc requests for data and products (”pull”)
 FWIS should be reliable, cost-effective, modular, scalable,
and flexible to support:
 Different user groups
 Various data policies, such as WMO Res. 40 and 25
 Data as well as network security
 Integration of diverse datasets

Impact on and benefits for WMO
• FWIS concerns only telecommunication and data management
functions of the WMO and does not affect the data processing
components of any WMO Programme.
• Provision of data and products on the basis of request/reply
services would likely be the most significant addition.
• Programmes would benefit from the services offered by FWIS
for the implementation of their data exchange tasks.
• For individual users, either a person or an institution, FWIS
would provide a single entry point for any data request, be it on
a routine basis by dissemination of certain user defined
information sets or on an ad-hoc basis for a special data set.
• By making use of off the shelf technologies of a lower cost,
FWIS would allow least developed Members, for the first time, to
actively participate in the WMO Programmes, specifically the
WWW.

How could FWIS be constructed?
• A GISC is a new development (metadata directories, etc.)
• The NC and DCPC basically already exist and add interfaces for
new services
• A pilot project for GISC development is the RA-VI VGISC project
• Development of more GISC’s projects, e.g. RA-II project
• Workshop in conjunction with CBS-Ext(06)
• Trials of inter-GISC communication after 2006
• Phased implementation of FWIS from 2008 onwards

RA-VI VGISC Project
• In 2001, RA-VI decided to create a project for the
development of a prototype GISC.
• The NMSs of France, Germany and the UK have
volunteered to jointly design and implement a virtual
GISC (VGISC) shared by their Services and to
include the ECMWF and EUMETSAT as DCPCs into
the concept, funded partially as EU project SIMDAT.
• A proof-of-concept system was demonstrated during
CBS XIII.

„CBS XIII was also very pleased to note the success of the first
phase of the Virtual Private Network project in Regions II and V, and
that the pilot project would be significantly expanded with additional
components, including prototype applications, and more
participating NMHSs in the years 2005-2006."

Inter-Commission Coordination Group on FWIS
(ICG-FWIS)
Created in 2004 by EC-LVI through Resolution 2.
Terms of reference:
• To coordinate the refinement and consolidation of the FWIS based on the
approved concept and then the implementation planning phases;
•
To assess in detail the data exchange and data management requirements
of WMO Programmes, at present and for the foreseeable future, which
should be met by the FWIS;
•
To advise the technical commissions on the development in datacommunications and management functions to be required in the FWIS as
regards their respective programmes;
•
To guide the orderly evolution of existing WMO information systems
towards FWIS;
•
To address the major issues that had been identified.

Inter-Commission Coordination Group on FWIS
ICG-FWIS (First meeting in Geneva, 12-14 January 2005) recommended coordination
mechanisms for the FWIS development and future activities:
 Support of the proposed CBS Inter-Programme Expert Team on Metadata
Implementation, Expert Team on FWIS GISCs and DCPCs and Expert Team on
FWIS/GTS Communication Techniques and Structure.
 Strongly supported the establishment of TCs’ Expert Teams that are relevant
to FWIS (data-management, metadata, XML, data-exchange) and their mutual
cooperation and coordination for fostering consistent and rapid FWIS
development
 Metadata aspects are crucial for the FWIS development and should be quickly
consolidated, full endorsement of the WMO Core Profile of the ISO Metadata
Standard.
 Recommendation for organizing a inter-programme workshop on metadata,
jointly with CBS/IPET-Metadata, by September 2005 and a workshop on GISC
development, jointly with CBS/ET-GISC&DCPC (1 Q 2006)
 Importance of the development of new Programme’s pilot projects to promote
an early introduction of FWIS elements
 Recommendation to rename FWIS as WIS (WMO Information System)

Summary
•
•
•
•
•
The WIS would be used for the collection and sharing of information for
all WMO and related international programmes.
The WIS vision provides a common roadmap to guide the orderly
evolution of the information system functions performed by current
WMO Programmes into an integrated system that meets efficiently all
of the requirements of Members for the relevant international
environmental information.
The support and involvement of regional associations and technical
commissions is needed, as early as possible, in all phases of the WIS
development in order to ensure a full and shared ownership of the
project, and its effective implementation.
There should be a workshop on WIS in conjunction with CBS-Ext(06)
The implementation of WIS needs to be done in a phased approach in
order to support the IPY (International Polar Year 2007/2008) and
THORPEX.
