WIS1 to WIS2 Migration

Background

The World Meteorological Organization (WMO) Information System (WIS) connects all National Meteorological and Hydrological Services and regions together for data exchange, management and processing. WIS provides an integrated approach to exchanging large data volumes such as new ground and satellite based systems, finer resolutions in numerical weather prediction, and hydrological models and their applications. WIS is the vital data communications backbone for integrating the diverse real time and non real time high priority data sets, regardless of location. 

WIS1/WIS2 Work

WIAD is involved in a variety of activities related to WIS.  For WIS1, the WIAD Data Services Team migrated the operational GISC-Washington service to the DIS Cloud.  The Data Services Team continues to provide Tier 3 support for operational GISC-Washington as well as associated O&M responsibilities. The WIAD Data Services Team is also supporting the WIS 1.0 to WIS 2.0 transition. 

The goal of WIS 2.0 is to ensure no WMO member is left behind by making international, regional and national data sharing simple, effective, and inexpensive. This is being accomplished by adopting open standards and web technologies to facilitate sharing of increasing variety and volume of real-time data, in addition to the creation of a new data-sharing infrastructure. The users of WIS 2.0 will be able to access data in real-time by subscribing to the MQTT NWS Global Broker Service and receive notifications when new data are available for download from the NWS Global Cache Service or from the origin NWS WIS2 Node data provider. A WIS2node is a National Met Center, basically a provider of weather data that users can subscribe to via a Global Broker Service.  The WIAD Data Services team will be migrating prototype versions of a  Global Broker and WIS2node service into the Dissemination Cloud as operational services by March 2025.
