• The EUMETSAT Polar System (EPS) is the European contribution to the Initial Joint Polar System (IJPS) established with NOAA;
• The IJPS will provide global meteorological and climate data from a series of European and American sun-synchronous polar orbiting satellites, comprising NOAA N&N´and Metop 1 & 2.
• EUMETSAT has established Co-operation Agreements with: ESA, for the development and procurement of the three Metop satellites;
NOAA, for the exchange of instruments, data and operation cross-support;
CNES, for the provision of IASI and ARGOS-DCS payloads;

Conclusions: EPS provides (1) • Continuity to the current system;
• High level sounding performances: provide enhanced data streams needed to further improve the capabilities of advanced NWP systems;
• Multi-instrument capabilities: assure service beyond operational meteorology, e.g. climate research and monitoring);
• Instruments built on the heritage of Earth observation missions (GOME, ASCAT). These are introduced into an operational environment;
• Long mission duration (14 years). This will assure that users are provided with long-term near real-time and off-line data service for meteorological and climate applications
