Cg-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 the Future WMO
Information System (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.
EC-LVI (2004):
Identified FWIS to be one of the key contributions of
WMO to GEOSS
(F)WIS brings new features and opportunities
• Common to all WMO programmes
• Inter-disciplinary locating, retrieval and
exchange of information in real and non-real
time
• On-line catalogues using metadata based on
ISO 19100 (geographic information standard)
• Industry standards and off-the-shelf hardware
and software systems to ensure costeffectiveness and inter-operability
Interoperability of Information
Systems
Example of queries:
Where to find data on the Antarctica
for the period 1950-1960?
How to get them?
Network
NETWORK
Network
How to use them?
At present, WMO Programmes do not offer
appropriate response to such queries in quasi realtime
Structure of (F)WIS
• National Centres (NC)
• Global Information System Centres (GISC)
• Data Collection and Production Centres (DCPC)
• Data communication networks
National Centre (NC)
• Several NCs in a country are possible (not just the NMC)
• Exchange information collected or generated in the
country with the GISC or DCPC
• Serve as portal for national users and administrate their
access to FWIS
Data Collection and Production Centre (DCPC)
• Serve as information production facilites in response to
stated requirements
• Facilitate access/exchange from/with NCs and GISCs
• Support information “Push” and ”Pull” mechanisms
• Generate, maintain and provide metadata catalogues of
their information
Global Information System Centre (GISC)
• Receive information from NCs and DCPCs
• Exchange information with other GISCs
• Disseminate, within its area of responsibility, the entire
WWW set of data and products for routine global
exchange (GTS function)
• Maintain metadata catalogues
• Ensure around-the-clock, reliable and secure operations
(F)WIS implementation
• Build upon the most successful components of existing
WMO systems and prepare a smooth and coordinated
transition
• Map existing WMO Programme centres into the
functional (F)WIS centres (e.g. WWW/RSMC <=>DCPC)
• Evaluate functions, technologies and architecture
through pilot projects and prototype solutions
• Ensure a flexible system structure that can respond to
growing requirements and technological progress
(F)WIS implementation
The information and communication functions of existing WMO
Programme centres are mapped into the corresponding
functions of (F)WIS centres as illustrated below for the WWW:

and communication)

From the GTS towards the (F)WIS core network
• Expanding bandwidth
• Flexible connectivity
• Saving recurrent costs
• Internet like applications
• Flexible services
• Saving implementation costs
and human resources

Several current pilot projects test and evaluate various
functional concepts and architectures and thus spearhead
the implementation of (F)WIS
•
RA VI VGISC : Exeter, Offenbach, Toulouse, ECMWF and EUMETSAT are
developing a distributed GISC – prototype demo at CBS-XIII
•
EUMETNET - UNIDART: data portal
•
RA II & V VPN Project: VPNs via Internet linking NMCs in the Regions
•
Roshydromet CliWare project (CCl)
•
WAMIS (CAgM)
•
Cooperation with Earth Sciences Portal, NCAR, etc
•
Test and evaluation of WMO Core Metadata standard coordinated by
focal points of the TCs
Impact on and benefits for WMO
• (F)WIS concerns only information exchange and data
management functions and does not affect data processing
components.
• (F)WIS maximizes cross-programme standardization
related to data and data connectivity between all
applications
• (F)WIS information cataloguing and metadata ensure
finding of and access to information by each user (person
or institution) within established data policies
• (F)WIS is a cost-effective comprehensive solution for
developing countries to actively participate in the WMO
Programmes
Inter-commission
Coordination Group on FWIS
• Established by EC-LVI as a coordination and
collaboration mechanism spanning across the
technical commissions and reporting to EC
• Includes TCs’ representatives and other ad-hoc
experts
• Facilitates sharing of knowledge, resources and
commitment to strengthen the FWIS development
and implementation processes
• First session: 12-14 January 2005
Frequently asked questions
Q1:
Will there still be a GTS data exchange mechanism as
we know it today?
A1:
Yes, but more flexible and based on WMO TDCF
Q2:
With several NCs within a country, what is the role of
the NMC/RTH?
A2.1:
Only the NMC/RTH manages the GTS traffic according to the
WMO Manual on the GTS
A2.2:
The NMC/RTH is the network coordinator for connection and
access rights of the “other” NCs
Q3:
Who are the so-called “other” NCs in a country?
A3:
Examples are national or international data centres,
academia, research institutions, commercial service
providers if permitted according to A2.2
Frequently asked questions
Q4:
What can a NC gain through the connection to
(F)WIS?
A4:
Cost-effective, standardized access to a wealth of national
and international data archives and data bases of the
GEOSS; in reverse, the international user community can
obtain access to the data bases and archives of the NC in
conformity with established data policies
Q5:
Is there a financial and administrative burden on the
NMC/RTH?
A5.1: Financial - That depends how the national network is
organized;
if the “other” NCs are directly connected to the Network
Service Provider: NO!
if their data flow through the NMC/RTH: YES!
A5.2: Administrative – NO! at least not more than in the current
GTS/RMDCN situation
Frequently asked questions
Q6:
Will the (F)WIS in conformity with the WMO data
policy (e.g., Res. 40 (Cg-XII) and Res. 25 (Cg-XIII),
and is it flexible enough to permit an evolution of the
WMO data policy?
A6.1: Yes, the management and practices related to essential and
additional data and products and related conditions will
remain unchanged
A6.2: Procedures for the management of access rights, control of
data retrieval, registration and identification of users, etc.
can be defined as and when required
A6.3: Anonymous downloading is technically possible, but depends
on whether a NC permits that feature
Frequently asked questions
Q7:
Are there implications in connection with relevant
international law, convention, such as copyright,
patent, etc.?
A7:
(F)WIS has no inherent or system-specific features that
would violate international legal frameworks; the control
procedures are fully within the responsibility of the
NMCs/RTHs
