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 NNand 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
