  11. EUMETSAT Mandate for Post EPS • EUMETSAT’s Objectives • Operational Meteorology • Climate Monitoring 25 year Strategy Environmental services (oceans, atmosphere, land, biosphere, natural disasters – if driven by or driving meteorology and climate) Mandatory Programmes Continuation of observations from geostationary and polar orbits Support to GMES: Establish a European capacity for the provision and use of operational information for Global Monitoring of Environment and Security

  12. EUMETSAT Strategic Guidelines for Post-EPS • EUMETSAT will remain committed, as a minimum and top priority, to • the mid - morning sounding mission There is a joint commitment between EUM Member States and NOAA for a future Polar System (JPS) • Possible EUMETSAT contribution to a JPS fully open: • - instruments across the various orbits; • - satellites on different orbits; etc. • EUMETSAT will keep responsibility for at least one end-to-end system • Need date for the core mission with instruments for Atmospheric Temperature and Humidity Sounding 2018 (1st piority) , followed by the remaining missions in 2020

  13. Post-EPS and GMES Possible Synergies Post-EPS Candidate Missions Applications Atmospheric Temp/Humidity ESA GMES Space Components Ocean Surface Topography, Wave/Winds Sea Surface Temperature Ocean Colour Sea Ice Sentinel 3 Atmospheric Chemistry Ozone Layer & Surface UV Air Quality Climate Change Sentinel 5 (polar orbit) Sentinel 4 (geosynchronous orbit – synergy with Meteosat Third Generation)

  14. Post-EPSCandidate Missions Note: Rank value 3: highest priority

  15. Space Weather: Observation of free electron content • Space weather manifests itself through the amount of free electrons in the ionosphere • Measuring the free electron content (FEC) provides in principle a way of estimating geomagnetic storm activity, different approaches exist to measure the FEC from satellites: • Doppler Orbitography and Radiopositioning Integrated by satellite (DORIS) • GPS radio occultation measurements (RO) • Dual frequency altimetry (ALT) • Post-EPS includes RO and ALT missions with the potential to measure • Total electron content of the ionosphere (ALT and RO) • Free electron density profile (RO)

  16. Ongoing activities for Post EPS • Formulation of requirements on the RO and ALT missions to add the capability of measuring the free electron content • Improve understanding of relationship between total electron content as seen by ALT and relate FEC variability to solar radio flux and geomagnetic disturbance index • Study of utility of triple-frequency GNNS signals in RO measurements with respect to: • Observation of space weather • Possible improvement of ionospheric correction in RO measurements compared to dual-frequency measurements • Study possibility of measuring the S4 scintillation index using RO
