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
