What is WIS?

In the recent years, WMO specified a new way of exchanging and sharing Met data at international level: the WIS. The GTS network, well known for decades, is now evolving towards the WIS.

“The WMO Information System is the pillar of our strategy for managing and moving weather, climate and water information in the 21st century” said WMO Secretary-General.

WIS stands for: WMO Information System

  • The WIS turns the existing network (the GTS) into a Web-based environment
  • The WIS allows a worldwide access to any Meteorological data using a Google-like search engine
  • The WIS allows to share data at world level by standardization of data description and databases

The implementation of the WIS is based on current WMO Information systems in a gradual and evolutionary process. It consists of two steps that are developed in parallel:

  • Step A: Continued strengthening and improving of the GTS to provide WMO programs with data which is absolutely necessary for their operations or for which the time factor plays a vital role.
  • Step B: Expansion of information through flexible search services, consulting and data retrieval services to authorized users, flexible and prompt transmission services. The Internet plays a vital role here.

Your needs

WMO is requiring that each National Met Service enters the WIS, by becoming either a GISC, a DCPC or a NC.

Your need is to join the WMO WIS community / network, in compliance with the WMO WIS Technical Specifications.

You need a system (software + hardware) to build your GISC / DCPC / NC.

The Met Service Managers, as well as Technical Director, Engineers, Administrators, Operators and Users must be trained about WIS.

You need an accompaniment to walk the road of WIS step by step up to WMO auditing and going operational.


MESSIR-WIS is a software package which will allow you to become a GISC, DCPC or NC.

Thanks to MESSIR-WIS you will go through WIS steps A and B to enter the WMO WIS community and reap the benefits.

WIS Step A is ensured by the development and consolidation of traditional GTS switching capacities with MESSIR-COMM.

WIS Step B is implemented by the various MESSIR-WIS modules: WIS-compliant Web Portal, Metadata Management, Synchronization with other WIS centres around the world.

MESSIR-WIS Main Functions

MESSIR-WIS allows your Met Centre to offer to end-users:

  • a DAR catalogue (Discovery, Access and Retrieval) to discover and find meteorological products by their description and geographical location
  • Automatic reception of selected products on routine basis

MESSIR-WIS allows your Met Centre to:

  • Forward (upload) your national data to WIS users / other WIS centres
  • Identify (control) customers and users; assess their "role"
  • Manage end-user subscription to receive selected products on routine basis
  • Edit Metadata (Metadata editor) so that product providers can describe their products
  • Synchronize metadata catalogues with  other WIS centres around the world
  • Upload and share weather and climate added value products
  • Download data and products via available networks / circuits
