Global Telecommunication System (GTS)

It was established by the World Meteorological Organization and is used by national meteorological services (NMS) throughout the world.

WMO's Global Telecommunication System is the communications and data management component, that allows the World Weather Watch (WWW) to operate through the collection and distribution of information critical to its processes.

The system is implemented and operated by national meteorological services, of WMO members, and international organisations, such as ECMWF and EUMETSAT. This secured communication network enables real-time exchange of information, critical for forecasting and warnings of hydrometeorological hazards, in accordance with approved procedures.

EUMETSAT and its partners use the GTS to deliver the following services:

• Metop/NOAA Global Level 1 products and Level 2 products (see GTS Abbreviated Bulletin Headers for Metop) and Regional EARS products
• Jason-3 Operational Geophysical Data Record (OGDR) products
• Meteorological and environmental products from the EUMETSAT ground segment
• Meteosat Data Collection Services DCP bulletins
