OF GISC, DCPC, AND NC
Presented by Eliot Christian <[email protected]> to the
Meeting of the CBS ICT-ISS
COMMISSION FOR BASIC SYSTEMS, IMPLEMENTATION-COORDINATION TEAM
ON INFORMATION SYSTEMS & SERVICES
GENEVA, 10 - 12 November 2008
Vision and Goals of WIS
According to WMO Congress (2003), WIS will:
 Be used for the collection and sharing of information
for all WMO and related international programmes;
 Provide a structure that allows participating centres
to enhance capabilities as their responsibilities grow;
 Build on the most successful components of existing
WMO information systems in an evolutionary process;
 Pay attention to a smooth and coordinated transition;
 Build on WMO GTS and the Improved
Main Telecommunication Network (IMTN);
 Utilise international industry standards for protocols,
hardware and software.

Vision and Goals of WIS (2007)
WIS is to provide three types of services:



Routine collection and dissemination service:
for time-critical and operation-critical data and products
based on real-time “push” via dedicated telecommunication
Data Discovery, Access and Retrieval service:
based on request/reply “pull” via Internet
Timely delivery service for data and products:
based on delayed mode “push” via combination dedicated + public
Congress emphasized evolving WIS from two parallel parts:


Part A: continued consolidation and further improvements of
GTS for time-critical and operation-critical data
Part B: extension of services through flexible data discovery,
access and retrieval services, as well as flexible timely delivery

Authority of
WIS Compliance Specifications
 Existing centres within WMO Member States may
apply for designation as one of the functional centres
forming the core infrastructure of WIS:
 Global Information System Centres (GISCs)
 Data Collection or Production Centres (DCPCs)
 National Centres (NCs)
 Designation requires a statement of compliance
with required WIS functions, compiled by the InterCommission Coordination Group on WIS (ICG-WIS)
 The approved WIS Compliance Specifications
are the authoritative source for interoperable
interfaces required of WIS GISCs, DCPCs, and NCs
