A Major Cooperation Between Europe and the USA

  • IN THE MARGINS OF THE G7, EUROPE AGREED IN PRINCIPLE TO SHARE THE BURDEN OF THE METEOROLOGICAL POLAR SERVICE WITH THE USA

  • INITIAL JOINT POLAR SYSTEM (IJPS) TO BE IMPLEMENTED

    • In the context of the USA Convergence

    • Under a NOAA-EUMETSAT cooperation agreement signed in November 1998

    • Through integration & coordination of the NOAA POES and the EUMETSAT EPS (EUMETSAT POLAR SYSTEM) Programmes

  • SCOPE OF COOPERATION

    • Afternoon & early morning orbits covered by the USA (POES & DMSP Satellites)

    • Morning orbit covered by Europe (Metop Satellites)

    • Exchange of instruments and data, coordinated development and operations

The EPS Programme Within IJPS

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
