  2. “The GOS is comprised of more than the Space-based component” Miroslav Ondras 28 September 2010 Geneva, Switzerland

  3. Surface-based component Upper Air component Airborne component (AMDAR) Other Observation Department entities: Climate Data and Monitoring (Baddour) Linkages with Commissions (CIMO, CBS, CCl)

  4. Evolution of the WMO Space-based Global Observing System (GOS) 1961 1978 2009 1990

  5. Space-based Component of the GOS

  6. Satellite Missions in the Vision of the GOS to 2025 Heritage operational missions • GEO: imager, HS IR sounder, lightning • Sun-synchronous: imager, IR/MW sounders • Ocean surface topography constellation • Radio-Occultation Sounding constellation • Ocean Surface Wind constellation • Global Precipitation constellation • Earth Radiation Budget (incl. GEO) • Atmospheric Composition (incl. GEO) • Ocean colour and vegetation imaging • Dual-angle view IR imagery • Land Surface Imaging • Synthetic Aperture Radar • Space Weather • VIS/IR imagers in HEO • Doppler wind lidar, Low-frequency MW • GEO MW • GEO High-resolution narrow-band imagers • Gravimetric sensors Transition from R&D to operational status Other application areas Operational pathfinders and demonstrators

  7. Satellite Missions in Vision for the GOS in 2025 Current Baseline • GEO: imager, HS IR sounder, lightning • Sun-synchronous: imager, IR/MW sounders • Ocean surface topography constellation (Jason-2, -3, Sentinel-3) • Radio-Occultation Sounding constellation (METOP/GRAS) • Ocean Surface Wind constellation (METOP/ASCAT) • Global Precipitation constellation • Earth Radiation Budget (incl. GEO) (Meteosat/GERB) • Atmospheric Composition (incl. GEO) (METOP/IASI, MTG/Sentinel-4, EPS2G/Sentinel-5) • Ocean colour and vegetation imaging • Dual-angle view IR imagery • Synthetic Aperture Radar • Land Surface Imaging • Space Weather • VIS/IR imagers in HEO (PCW and Arktica) • Doppler wind LIDAR, Low-frequency MW • GEO MW • GEO High-resolution narrow-band imagers • Gravimetric sensors Transitional Baseline Demonstrations

  8. Satellite Missions in the Vision of the GOS to 2025 Implementing the new missions of the Vision ….

  9. Long-term Observations are Needed for Climate Monitoring 9

  10. As we look back in time from 2100, what will be the analog for climate monitoring? • anomaly correlation of seasonal forecasts? • ? • ? • ?

  11. Challenges • Continuity and improvement of operational constellations • Sustained observation of all ECVs observable from space • Transition Research to Operations for priority, mature observations • Generation of QC products • Integration : network optimization, system interoperabilitycomposite products

  12. ARCHITECTURE FOR CLIMATE MONITORING FROM SPACE • DRAFT OUTLINE OF THE CONCEPT DOCUMENT • Introduction • Motivation • A Structured Approach • User Requirements • Observational Capabilities • ECV Product Generation • User Interface • Coordination
