  1. Climate Monitoring from Space -- A Call for an International Architecture WMO Space Programme Geneva, Switzerland

  2. Overview • Motivation • WMO Global Observing System (GOS) – yesterday, today, and tomorrow • Key elements in place • The Way Forward

  3. Motivation • Policy framework in place (UNFCCC, GFCS) • Expectations are high • Space-agency investments need to be leveraged • Contingency measures exist for weather observations, but not for climate • Observational gaps exist • More coordination is needed

  4. Ten Years Ago . . . “Commitments to address requirements would allow evolution of the GOS that would help characterize the total Earth and climate system on a variety of time and space scales. . . “ From WMO Executive Council LIII, June 2001, Final Report

  5. Five Years Ago . . . www.ceos.org While in situ measurements will remain essential . . . Earth-observation satellites are the only realistic means to obtain the necessary global coverage, and with well-calibrated measurements will become the single most important contribution to global observations for climate.

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

  7. Space-based Global Observing System Schematic Modified from GEO Secretariat

  8. Satellite Missions in Vision for GOS in 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 • Synthetic Aperture Radar • Land Surface Imaging • 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 Operational pathfinders and demonstrators

  11. ConsistentCalibrateddata sets Essential Climate products Satellite data Satellites & sensors Users GSICS GOS SCOPE-CM Key Elements in Place • Requirements Gathering and Articulation – GCOS ECVs • System Capabilities and Gaps – WMO Dossier, CEOS MIM • Vision of the Global Observing System (GOS) in 2025 • CEOS Virtual Constellations • CGMS Contingency Planning and Commitments • Global Space-based Inter-calibration System (GSICS) • Quality Assurance Frameworks – QA4EO, WIGOS • Sustained Co-Ordinated Processing of Environmental satellite data for Climate Monitoring (SCOPE-CM)

  12. Great Advances in Weather Forecasts

  13. Similar Advances for Climate? • What will be the analog for climate and will the end-to-end system exist to produce results? • Anomaly correlation of seasonal forecasts? • Correlation of sea-level rise? • ?

  14. The Way Forward • Implement the Vision for the GOS in 2025 • Leverage the end-to-end system that exists for Weather for Climate • Increase coordination and cooperation – recognizing different, but complementary roles and responsibilities

  15. Summary • Key elements in place – must leverage these efforts • Challenges (and opportunities) • Continuity – missions, instruments, measurements • Sustained observations • Increased integration • Both R&D and operational entities are needed for climate monitoring
