WIS2 Operational Newsletter (No.2)

WIS 2.0 Global Services provide a set of centralized capabilities that support efficient, reliable, and resilient global data exchange. They enable data discovery, access, monitoring, and notification distribution, ensuring high availability and seamless collaboration among data providers and users worldwide. 

WIS2 Global Services include:

• Global Broker: Distributes notification messages across the system for real-time data discovery.
• Global Cache: Stores and provides access to frequently requested data, improving efficiency and reducing latency in data retrieval.

• Global Discovery Catalogue: Enables users to search for and browse metadata descriptions of published data.

• Global Monitor: Tracks data publication, accessibility, and system performance to ensure reliability. 

During the transition period, the following temporary services are also available:

• GTS-to-WIS2 Gateway: Publishes all data on the GTS onto WIS2

• WIS2-to-GTS Gateway: Publishes a subset of data on WIS2 onto GTS  

For an overview of the WIS 2.0 Global Services and their endpoints, please visit this page: WIS 2.0 Global Services 

You can find the up-to-date list of operational WIS2 Nodes in the WIS2 Global Registry which is maintained by the Secretariat. As of 15 December, around 90 WIS2 nodes are registered as Operational WIS2 nodes.

The table below shows the list of new Operational WIS2 Nodes registered in last 12 months illustrating the significant progress made, especially in region I.

The redesigned landing page now defaults to the NWP module, with tabs providing access to the GBON, GCOS, and Transition Monitoring modules. 

This module, along with updated user manual documentation, will become operational on 12 January 2026. Feedback and comments are welcome and can be sent directly to wiswmo [dot] int (wis[at]wmo[dot]int) or tproescholdtwmo [dot] int (tproescholdt[at]wmo[dot]int)

 To evaluate performance and ensure the reliability of WIS 2.0 Global Services, a dedicated WIS2 Test Infrastructure has been established. This infrastructure provides a controlled and isolated environment equipped with the tools and resources required to validate the functionality, integration, and overall performance of WIS 2.0 components, without risking disruption to the operational WIS2 system.

 The WIS2 Test Infrastructure is a replica of the operational WIS2 environment and is intended exclusively for testing purposes, not for operational data exchange. It supports the evaluation of WIS2 Global Services and enables WMO Members and industry stakeholders to assess the readiness of their WIS2 nodes prior to deployment into production.

By offering a secure and controlled testing environment, the infrastructure facilitates the identification of potential issues, optimization of configurations, and verification of seamless integration with WIS 2.0. It includes the systems and tools necessary to conduct a wide range of tests, supporting in particular:

• Continuous improvement of WIS2 Global Services, through iterative development, testing, and timely resolution of issues as WIS 2.0 evolves;
• Performance evaluation of WIS2 Global Services, ensuring reliability, scalability, and efficiency;
• WIS2 node readiness, by providing the tools and environment needed to validate WIS2 nodes and confirm compliance with WIS 2.0 standards.

The first release of the WIS2 Cookbook is now available! It is designed to help users get started quickly and confidently with WIS 2.0, with more recipes to follow in future editions.

In conjunction with the Manual on the WMO Information System volume II (WMO-No. 1060) (Manual on WIS volume II: WIS 2.0), the present Guide to the WMO Information System volume II (Guide to WIS volume II: WIS 2.0) is designed to ensure adequate uniformity and standardization in the data, information and communication practices, procedures and specifications employed by Members of the World Meteorological Organization (WMO) in the operation of the WMO Information System WIS 2.0 as it supports the mission of the Organization. 

The Manual on WIS contains standard and recommended practices, procedures and specifications. The Guide to WIS contains additional information concerning practices, procedures, and specifications that Members are invited to follow or implement in establishing and conducting their arrangements in compliance with the WMO Technical Regulations and in developing meteorological and hydrological services.

Building on this foundation, the WIS 2.0 Cookbook provides various code snippets, recipes and workflow examples in support of WIS2 requirements.  

This cookbook is a practical, implementation-oriented guide designed to support WMO Members, WIS Centres, and partners in deploying and operating WIS 2.0 components. It complements the formal WIS 2.0 technical regulations and standards by translating them into clear, step-by-step guidance, examples, and best practices.
