WMO INFORMATION SYSTEM (WIS)---

COMPLIANCE SPECIFICATIONS OF GISC, DCPC, AND NC

Presented 10 June 2008 at the

"Ad-hoc Information and Advisory Meeting on the Region VI VGISC-DCPC project"

(EUMETSAT, Darmstadt) by Eliot Christian <[email protected]>

10 Jun 2008 WIS Compliance Specifications of GISC, DCPC, and NC 2

Outline of WIS Compliance Specifications

Purpose and Authority of Specifications

Major Components and Services of WIS

Flow Diagrams amongst WIS Components

Technical Specifications of WIS Interoperable Interfaces


Purpose and Authority:

Purpose of WIS 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 Centre (GISC) Data Collection or Production Centre (DCPC) National Centre (NC)

Designation requires a statement of compliance with required WIS functions, compiled by the Inter-Commission Coordination Group on WIS (ICG-WIS)

The WIS Compliance Specification document provides technical specifications for required WIS functions


Purpose and Authority:

Authority of WIS Specifications

On approval, the WIS Compliance Specifications will be the authoritative source for technical specifications of interoperable interfaces required of core WIS components across GISCs, DCPCs, and NCs

It was expected that the WIS Compliance Specifications would be useful in an Invitation to Tender on software needed by a prospective WIS DCPC or GISC (e.g., the present European ITT for software to implement a Virtual GISC)


Technical Specifications will be part of WIS "regulatory documents"

Note: GTS Message Switching Systems (MSSs) in the VGISC Invitation to Tender

(ITT) DWD, Meteo-France and UKMO each

operate a GTS MSS The VGISC must interface to MSSs to:

- ingest and cache data and metadata - handle subscription and GTS link info - maintain control lists - provide failover support

Each of the three partners is responsible to adapt to the MSS interface provided by the VGISC software

FunctionInput Output

Controlsource data which is

transformed by the Function

the result of the transformation

carried out by the Function

identifies the resources/facilities that are used by the Function (e.g.

humans, computers...)

defines how the Function carries out the transformation
