WMO Information System (WIS)
In 2003, the World Meteorological Congress stated that an overarching approach for solving the data management problems for all WMO and related international programmes was required:a single coordinated global infrastructure, the WMO Information System (WIS).
April 10, 2023 WIS Overview 5
Vision of WIS
WMO Members decided that WIS will: • Use international industry standards• Build on the Global Telecommunication
System (GTS), with a smooth and coordinated transition;
• Provide time-critical data exchange, as well as data access and retrieval services;
• Support all WMO and related international programmes.
WIS services
WIS provides an integrated approach suitable for all WMO Programmes to meet the requirements of:• Routine collection and automated dissemination
of observed data and products (“push”);• Timely delivery of data and products (appropriate
to requirements);• Ad-hoc requests for data and products (“pull”).• Data discovery service for all data stored by any
WMO programme regardless of location.
WIS users
• WMO programmes who will benefit from the services offered by WIS for the implementation of their data exchange tasks.
• NMHS’s who will be able to interactively alter their operational data provisions
• Individual users, either a person or an institution, who will be the main beneficiary of WIS, because WIS will 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..
• GEOSS because WIS is a major contributing system and an exemplar implementation of the underlying interoperability principles of GEOSS.
WIS concept
• Global Information System Centres (GISC)
• Data Collection or Production Centres (DCPC)
• National Centres (NC)• Data communication
network
• Only GISCs are new centres

Global Information System Centres
(GISCs)
Data Collection or Production Centres
(DCPCs)
National Centres (NCs)
National Centres (NC)
• Collect observational data from within their country• Provide observations and products intended for global
dissemination to their responsible GISC (possibly via a DCPC)
• Provide observations and products intended for regional or specialized distribution to the responsible DCPC
• Collect, generate and disseminate products for national use.
• Participate in monitoring the performance of the system• Authorize their national users to access WIS, as required.
Data Collection or Production Centre (DCPC)
• Receive information intended for
dissemination to NCs within its
area of responsibility (i.e. regional
collection)
• Collect programme-specific data
and products
• Produce regional or specialized
data and products

• “Push” information intended for global exchange to their associated GISC
• Disseminate information intended for regional exchange
• Support access to their products via request/reply (”Pull”) mechanism
• Maintain data and product catalogues in a WMO-agreed standard format and facilitate
access to this catalogue
Global Information System Centre (GISC)
• Receive observational data and products that are intended for global exchange from NCs and DCPCs within their area of responsibility
• Exchange information intended for global dissemination with other GISCs
• Disseminate, within its area of responsibility, the entire set of data and products agreed by WMO for routine global exchange
• Hold the entire set of data and products agreed by WMO for routine global exchange for at least 24 hours and make it available via WMO request/reply (”Pull”) mechanisms
• Maintain, in accordance to the WMO standards, a catalogue of all data and products for global exchange and provide access to this catalogue to locate the relevant centre intended for global exchange.
• Coordinate the communication network within their area of responsibility

Benefits of WIS
In addition to improving efficiency, WIS:• Enhances collection of critical data• Catalogs all WMO data and products• Enhances availability of time-critical
data and products at all national centres• Opens up GTS to other types of data• Exploits technology innovation

WIS implementation status
• The Manual on WIS, and related amendments to WMO Technical Regulations (WMO-No.49) to be approved by Congress in 2011
• The Guide to WIS endorsed by CBS in 2010• First set of GISCs and DCPCs to be designated at
Congress in 2011• More DCPCs, including those in the climate
service area, will be certified and designated on a yearly basis by WMO Executive Council
