Introduction The Manual on the GTS (WMO-No. 386) and its guides provide important information on the operations, monitoring and security of the GTS. It also includes information on the Integrated World Weather Watch monitoring practices. 2. Guide to Integrated World Weather Watch Monitoring 2.1. Historically, the Regional Telecommunication Hubs (RTH) on the GTS have been an effective location for monitoring what observations have been available from the Global Observing System (GOS). Missing observations at the RTHs were indicative that the observations were not done or that they were not successfully exchanged across the GTS. Thus the WWW monitoring had two purposes. One was to check the traffic flow routing and switching of centres on the GTS, the second and most visible to Members was the monitoring of the GOS. Issues identified by the monitoring were followed up operationally for correction. Statistics on receipt of observations were published on the web and reported to constituent body sessions. 2.2. The method of capturing and analysing the data have also developed over the years, including the development of an Integrated World Weather Watch Monitoring system. However, global numerical weather analysis and prediction models through their assimilation processes have also developed monitoring and reporting mechanisms that provide information about observations which not only includes reception but also the information on the quality of the observations including biases. 2.3 From a WIGOS perspective, looking at the GOS and other contributing observing systems, the RTHs are not necessarily on the path of information transfer between observing systems and the end users. Thus, WIGOS is now implementing a monitoring system based on global NWP centres assimilation processes. However, the WWW monitoring has a long historic record of data availability and as such it is recommended that the WWW monitoring be continued to maintain continuity between historic records and future records of the new WIGOS monitoring.
