GISC Watch
GISC Watch introduction
The WMO Information System (WIS) serves as the global framework for the coordinated exchange and dissemination of meteorological and related data. Its performance and reliability depend on the operational quality of all Global Information System Centres (GISCs).
To ensure consistent global service levels, the GISC Watch procedure was first established by the TT-GISC in 2017 and entered its pre-operational phase in May 2018. Following its successful implementation, the Eighteenth World Meteorological Congress (Cg-18, June 2019) formally approved its operationalization through Resolution 57 (Cg-18), resulting in the publication of standardized procedures in the GISC Watch Guide (2020).
The GISC Watch Guide (2021 edition) consolidated these procedures and served as the official reference for GTS/WIS1 monitoring operations. GISC Watch operations for GTS/WIS1 were discontinued on 31 December 2024.
With the operational launch of WIS2 on 1 January 2025, a new monitoring framework was introduced to maintain consistent service performance across all WIS2 Global Services. The WIS2 GISC Watch, initiated in April 2025, succeeds the WIS1 procedure and ensures the continued operational quality and reliability of the WIS2 network.
The GISC Watch Guide for WIS2 (2025 Edition) adapts the original framework to the WIS2 framework. It introduces updated and standardized procedures for Take Over, Monitoring, Issue Management, Hand Over, and Escalation, guiding GISCs in effectively fulfilling their WIS2 Watch responsibilities and maintaining reliable global service performance.
