WMO Information System (WIS)
Direction from WMO Congress (2003)
• Develop:
–
–
Over-arching approach for solving data management
problems for all WMO and related international
programmes
A single, coordinated global infrastructure, the
WMO Information System (WIS) for the
collection and sharing of information
World Meteorological Organization
3
Reasons for WIS
• Various WMO Programmes developing
information systems independently
– Incompatibilities, inefficiencies, duplication of
effort and higher overall costs
• Continued systems development in an
uncoordinated manner would:
– Exacerbate these problems
– Increase difficulty in sharing information
between programmes
– Further isolate WMO Programmes from each
other and from wider environmental community

Current situation: GTS
For WWW
GTS provides:
• Information collection and distribution
o Real-time push for WWW data & products
(and some other programmes data)
• Information management
o Standard data formats
o Implicit metadata & catalogs
World Meteorological Organization

Current situation:
GTS and Other WMO Programmes systems
• Information exchange
o Multiplicity of procedures
o Real-time and non-real-time
o Very limited pull
• Information management
o Multiplicity of data formats
o Uncoordinated/lack of metadata & catalogs
o No discovery

WIS Vision
Integrated approach for all WMO Programmes
• Routine collection and dissemination of time-critical
and operation-critical data and products:
o Real-time “push” through dedicated telecommunication
• Data Discovery, Access and Retrieval service:
o “Pull” through the Internet (HTTP, FTP,…)
• Timely delivery of data and products:
o Delayed mode “push” through dedicated telecommunication
means and public data networks, especially the Internet
• Unified procedures
o More efficient data exchange
• Coordinated and standardized metadata
o Interoperability between programmes
o Improved data management
o ISO 191xxx series for geographic information

WIS brings new features and opportunities
• Common information exchange standards,
functions
and services for all WMO
programmes
• Inter-disciplinary discovery, retrieval and
exchange of information in real-time and
non-real time
• Inter-operability through on-line catalogues
using metadata based on ISO 19100
(geographic information standard)
• Industry standards and off-the-shelf
hardware and software systems to ensure
cost-effectiveness and compatibility
World Meteorological Organization

•
Ability to “push” to national users critical information:
o
4.
Warnings, advisories, selected measurements, etc.; (eg:
national agencies dealing in disaster mitigation, agriculture,
energy and water management,)
Better appreciation by partner agencies
•
Supports their “pulling” relevant information from WMO
World Meteorological Organization
11
Structure of WIS
Functional centres:
• National Centres (NC)
• Global Information System Centres (GISC)
• Data Collection and Production Centres (DCPC)
and
• Data communication networks
WIS concerns only information exchange and data
management functions
World Meteorological Organization
12
National Centre (NC)
• Provides information collected/generated in the country to a
GISC or DCPC
• Serves as portal for national users and/or administrates their
access to WIS
• Several NCs in a country are possible (not just the NMC)
Data Collection or Production Centre (DCPC)
• Provides the programme-related
international exchange
data
&
products
for
• Supports information “Push” and ”Pull” mechanisms
• Generates, maintains, makes accessible and provides to GISCs
metadata catalogues of its data & products
World Meteorological Organization
14
Global Information System Centre (GISC)
• Receives information from NCs and DCPCs
• Exchanges information (data and metadata) with other
GISCs
• Disseminates, within its area of responsibility, the entire
set of WMO data and products for routine global
exchange
• Supports information ”Pull” mechanisms
• Generates, maintains and makes accessible metadata
catalogues of all data and products for global echange
• Ensures around-the-clock,
operations
reliable

and
secure
15
WIS, a key issue: interoperability
Interoperability enables the discovery,
the retrieval and the usage of the data
It needs the development and the
implementation of relevant Metadata
standards
Development of a WMO Metadata Profile of
the ISO 191xx series for geographic
information
• Step 1: development of the WMO Metadata
Core Profile of ISO 19115 for data discovery
•Step 2: Use of the ISO 191xx series for the
access and use of the data
World Meteorological Organization
16
WIS SERVICES
WIS provide three types of services to meet the
different requirements:
(1)
Routine collection and dissemination service
for time-critical and operation-critical data and
products:
Based on real-time “push” mechanism (incl. Multicast);
implemented essentially through dedicated telecommunication means
with guaranteed quality of service, e.g. leased circuits, dedicated
data communication network services and satellite-based datadistribution systems;
(2) Data Discovery, Access and Retrieval service:
Based on request/reply “pull” mechanism with relevant data
management functions; implemented essentially through the Internet
(HTTP, FTP,…);
(3) Timely delivery service for data and products:
Based on delayed mode “push” mechanism; implemented through a
combination of dedicated telecommunication means and of public data
networks, especially the Internet.

WIS Data Policies
• Complies with WMO data policies
– Res. 40 (Cg-XII) and Res. 25 (Cg-XIII)
• Will follow evolution of WMO data policy
– Procedures for managing of access rights, control of
data retrieval, registration and identification of users,
etc can be defined, as and when required
– Anonymous downloading is technically possible, but
depends on whether a NC permits that feature
– Has no system-inherent features that would violate
international legal frameworks

WIS implementation
• Part A: GTS Evolution into WIS
– Provides consolidation/improvement for timecritical and operation-critical data
– Includes extension to meet operational
requirements of WMO programmes in addition to
World Weather Watch (including improved
management of services);
• Part B: Extension to WIS
– Provides for an extension of the information
services through flexible data discovery, access
and retrieval services to all users, as well as
flexible timely delivery services;
World Meteorological Organization

WIS services & implementation
• XV Congress recognized the routine
collection and dissemination service and
the timely delivery service should have
the highest priority.
• XV Congress emphasized that, in
implementing Part A, highest priority
should be given to overcoming the
persisting shortcomings in the current
GTS.

WIS governance
• XV Congress endorsed in principle, upon
ICG-WIS and CBS recommendations,
the procedures for the designation
Global Information System Centres
(GISC) and the Data Collection or
Production Centres (DCPC).
• Congress encouraged Members to
adhere to them until they would
eventually be included in WIS regulatory
documentation.
World Meteorological Organization
29
DESIGNATION PROCEDURES FOR GISCs AND DCPCs
i) Statement of WIS requirements
• WMO TCs and other bodies state & review their programmes
requirements for WIS services. WIS requirements and functions
are compiled and regularly reviewed by ICG-WIS and reported
to EC.
ii) Service offers by potential GISCs and DCPCs
• Existing centres from WMO systems and programmes may apply
for designation as GISC or DCPCs. The service offer addressed
to WMO should include:
• - A statement of compliance with the required WIS functions
- GISC: proposed area of responsibility for WIS data services
- DCPC: programmes’ candidate DCPCs endorsed by relevant TCs
- Formal commitment by the PR of the Member to implement the
GISC or DCPC and provide the WIS services.
• ICG-WIS analyzes the proposed services versus WIS
requirements and the compliance to the required WIS/GISC or
DCPC functions and specifications, and formulates a
recommendation.
World Meteorological Organization
30
DESIGNATION PROCEDURES FOR GISCs AND DCPCs
iii) Demonstration of GISC or DCPC capabilities
• Candidate GISCs and DCPCs demonstrate to CBS their
capabilities to provide WIS services to accredited users with
the necessary reliability and quality. Adherence to WIS
standards and relevant data exchange policies and access rights
must be granted. (real-time functions of data and product
collection and dissemination, non real-time services for requests,
storage functions, coordination / synchronization functions with
GISC, up-to-date metadata catalogues).
• CBS formulates recommendation for the GISC and DCPC
designation.
iv) Designation of GISCs and DCPCs
• The Executive Council considers for approval the ICG-WIS
recommendation and CBS recommendation for the GISC and
DCPC designation
• Upon EC approval, the GISC or DCPC is included in the relevant
WMO programme documentation.

World Meteorological Organization
32
Challenges
• Good progress made in concept, technological solutions
and prototypes for WIS, but much work to be done for an
operational WIS
• Understanding of WIS – both internal and external to
WMO:
– What it is, why it is important, what it does for NMHSs, what needs
to be done, …
• Active participation of WMO Technical Commissions and
other bodies -- stating requirements, developing
metadata and implementing WIS interface at their data
centres, etc
• Involvement of all NMHSs in the WIS development,
including awareness of users communities
• Adequate financial and human resources for WIS
development into operations
