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).

– WIS would be used for the collection and sharing of information for all WMO and related international programmes.

– WIS would provide a flexible and extensible structure that would allow the participating centres to enhance their capabilities as their national and international responsibilities grow.

– Implementation of WIS should build upon the most successful components of existing WMO information systems in an evolutionary process.

– WIS development should pay special attention to a smooth and coordinated transition. – The basis for the core communication network should be the communication links used within

the World Weather Watch (WWW) for the high priority real-time data.– WIS should utilise international industry standards for protocols, hardware and software.

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.

A short introduction to WIS can be found in “WIS in a Nutshell”, initiated by the RA-VI Task Team on WIS.

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 could also form the base for its information systems .

WIS concept

• National Centres (NC)• Global Information System Centres (GISC)• Data Collection or Production Centres (DCPC)• Data communication network

The names of these virtual centres describe their functionality, not the actual organisational entities. There may be organisations, such as NMHSs, which combine all three virtual centres within one facility.

WIS metadata

• WIS metadata describes WMO data and products and is essential for discovery

• Metadata is maintained by NCs and DCPCs

• GISCs already synchronize catalogue information

• The figure shows

It should be noted that so far no NC’s have been endorsed world-wide. Therefore, it was felt necessary to create a WIS implementation plan, starting with RA-VI .

- 21 -


Background for implementation plan

• Decision by Regional Association VI (Europe), Fifteenth session, 18-24 September 2009

• Action by Working Group on Technology Development and Implementation (WG-TDI), First Meeting, DWD, Offenbach, Germany, 27 – 28 October 2010

• Support at WMO RA VI Workshop on the implementation of WIS, Sofia, Bulgaria, 1 – 3 November 2011

• Statement by WG-TDI during its second meeting at Météo-France, Paris, 15-16 December 2011 that the task for developing a detailed RA VI WIS Implementation Plan should be given high priority with the goal that the implementation would be completed by the next session of RA VI in September 2013.

Pre-requisites for use of WIS NMHS

• Nominate WIS Focal Point to WMO• Check availabilty of network connections to GISC‘s

– Maybe involve intermediate DCPC (previously RTH)

• Check bandwidth requirements for dissemination schedule– Maybe join RMDCN if not done yet

• Agree on primary GISC with relevant GISC and inform WMO• Develop local plan for WIS implementation• Check dissemination schedule at GISC• Update metadata records of data supplied by own country • Participate in training courses and meetings organised by GISC• Provide monitoring information to WIS Contact Point at WMO

19 April 2023

- 28 -


Pre-requisites for use of WIS DCPC

• Agree with WMO program on need for particular DCPC• Inform WMO on wish to become a DCPC• Select primary GISC after consultation with GISC in RA• Install relevant WIS software

– DAR, metadata editor, …

• Obtain approval by CBS and EC• Set up metadata directory to be harvested by GISC• Start operations

19 April 2023

- 29 -


Potential problem areas

• Lack of staff resources for operational WIS centre– No WIS focal point

– Metadata knowledge not available

• Insufficient bandwidth for dissemination schedule– Priorization of traffic required

• Intermediate DCPC (RTH) unable to help– RMDCN connection too costly

• No interactive Internet access to GISC possible

19 April 2023

- 30 -


Monitoring

• WMO RA-VI WIS Focal point to be nominated• Country data base to be installed at WMO or some regional

GISC with: – Contact information (national WIS Focal point)– Network connection details and traffic patterns– Local implementation plan details and results – Specification of problem areas and failures

• GISC to keep records of traffic and problems encountered for each connected centre of its AMDCN

• GISC to undertake metadata training courses and to report on metadata use by connected centres

• GISC to organise regular users‘ meetings and to report on problems

• RTH as DCPC to take over role of GISC for centres connected

19 April 2023

- 31 -


Execution of plan

• GISC‘s should organise users‘ meeting and metadata training courses at the latest during 3rd quarter 2012

• The implementation of WIS should proceed according to local plans coordinated with the primary GISC and the WMO RA-VI WIS Focal point starting in autumn 2012

• During first part of 2013 all Members of RA-VI should have a local plan for WIS implementation

• Review of progress of WIS implementation should be carried out by WMO RA-VI WIS Focal point in June 2013

• All Members of RA-VI should be WIS users by autumn 2013

Exemplary

WIS Implementation Plan for DCPC in RA-VI

19 April 2023

1. Bring about an internal decision of the organisation to join WIS in RA-VI as a DCPC.

2. Choose a staff member to become the WIS Focal point. The person should be knowledgeable about the GTS transmissions and the WMO Metadata Core Profile.

3. Gain the support of a WMO Program for the special data to be made available as a DCPC. In case of a current RTH who wishes to become a DCPC, the NC’s to be connected to the new DCPC for data collection and distribution services should be contacted for support, expressed by the relevant PR’s.

4. Determine which GISC in the region should become the primary GISC and communicate with the chosen GISC to gain its approval.

5. Check the communication network connectivity, in particular the bandwidth to the chosen GISC and the Internet access.

6. Check the planned traffic pattern for the data and the Internet interactive load, assuming full DCPC operations. Ensure that the bandwidth is sufficient to send and receive all data without undue delays. If this were not the case, make sure that an upgrade of the communication network is planned prior to starting operations as a DCPC.

7. In accordance with the mandatory services to be provided by a DCPC as described in the Manual on WIS (WMO-No. 1060), select the necessary special software and install it locally. Make sure that it passes all the tests for DCPC’s which have been published by WMO.

8. Inform WMO, in particular CBS, by letter from the Director of the Organisation about the wish to become a DCPC, the supporting WMO Program, the choice of the primary GISC and the nomination of the WIS Focal point.

9. In accordance with the WIS Manual, collaborate with the relevant CBS ET’s to pass all the necessary tests for a DCPC.

10. Once the tests have been passed successfully and the centre has been endorsed by WMO Congress / EC, set up operations as a DCPC.

11. Join the user group of the GISC by attending meetings and other organised events.

12. Support the monitoring of the regional WIS by regularly updating the organisation’s records in the Country Data Base including availability of service, traffic figures, errors and other comments. The WMO RA-VI WIS Focal point may contact the local WIS Focal point for clarifications and vice versa.
