In October 2008, a circular letter (see below) has been sent to Members with copy to Technical Commissions seeking their identification of potential GISCs and DCPCs for an inaugural list of potential WIS centres to be presented to CBS-XIV and Executive Council-LXI in 2009.

Three enquiries were previously made to Members, Technical Commissions and Programme Managers in connection with the planning and design process for the WMO Information System (WIS). These included:

  • in 2004 a letter directed to the Technical Commissions requesting input to the concept of WIS as a system to be used by all WMO and WMO-sponsored programmes;
  • in 2006 a questionnaire to Members surveying their potential contributions to WIS including identifying likely functional centres and associated information content;
  • in 2007 a questionnaire to WMO Programme Managers within the Secretariat and to the Presidents of Technical Commissions seeking feedback on user requirements for WIS.

Results of these enquiries have been included in the production of the initial Review of Requirements process, in the design of the Functional Architecture of WIS and in the specifications of WIS interfaces as described in the Compliance Specifications for WIS. These documents are all available on the WIS Reference Web page.
