  1. Developing a Space-based Architecture for Climate Monitoring EC-LXII Side Event WMO Geneva, Switzerland 11 June 2010 Barbara J. Ryan Director, WMO Space Programme

  2. Overview • Evolution of the WMO Global Observing System (GOS) • Vision for the GOS in 2025 (WIGOS) • Some key elements in place • The Way Forward

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

  4. Space-based GOS in 2010

  5. Satellite Missions in the Vision for the GOS in 2025 Heritage operational missions • GEO: imager, hyperspectral 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 (e.g. PCW and Arktica) • 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

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

  7. GCOS Essential Climate Variables (ECVs)(Space-based) • Terrestrial • T.1 Lakes • T.2 Glaciers and Ice Caps, and Ice Sheets • T.3 Snow Cover • T.4 Albedo • T.5 Land Cover • T.6 fAPAR • T.7 LAI • T.8 Biomass • T.9 Fire Disturbance • T.10 Soil Moisture • Atmosphere A.1 Surface Wind Speed and Direction A.2 Upper-air Temperature A.3 Water A Vapour A.4 Cloud properties A.5 Precipitation A.6 Earth Radiation Budget A.7 Ozone A.8 Atmospheric reanalysis (multiple ECVs) A.9 Aerosols A.10 Carbon Dioxide, Methane and other Greenhouse Gases A.11 Upper-air Wind • Oceans • O.1 Sea Ice • O.2 Sea Level • O.3 Sea Surface Temperature • O.4 Ocean Colour • O.5 Sea State • O.6 Ocean Reanalysis • O.7 Ocean Salinity

  8. For Long-term Observations – Research and Operational Satellite Data Must Contribute Source: NOAA 8

  9. Challenges forOperational Climate Monitoring • Continuity and improvement of operational constellations • Sustained observation of ALL Essential Climate Variables (ECVs) observable from space • Transition Research to Operations for priority, mature observations

  11. The Way Forward www.ceos.org . . . . both satellite and in situ data are required to better monitor, characterize, and predict changes in the Earth system. While in situ measurements will remain essential and largely measure what cannot be measured from satellites, 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.

  12. Summary • Key elements are already in place – must leverage existing efforts and existing coordination mechanisms • R&D and operational entities and activities complement each other – both are needed for the Way Forward • Challenges (and opportunities) • Continuity – missions, networks, measurements • Sustained observations are needed • Transition and integration elements • The Way Forward • Implement the Vision for the GOS in 2025 • Increase coordination and cooperation – recognizing different, but complementary roles and responsibilities • Bring the rigor of the existing Weather Constellation of GOS to a Climate Constellation – a Space-based Architecture for Climate Monitoring
