2. CEOS Virtual Constellations Constellation for Atmospheric Composition (ACC) To collect and deliver data to improve monitoring, assessment, and predictive capabilities for changes in ozone, air quality, and climate. Constellation for Land Surface Imaging (LSI) To determine optimal capabilities to acquire, receive, process, archive, and distribute land surface image data to the global user community. Constellation for Ocean Colour Radiometry (OCR) To provide long time series of calibrated ocean colour radiance (OCR) at key wavelength bands from measurements obtained from multiple satellites. The 23 rd CEOS Plenary I Phuket, Thailand I 3-5 November 20092

3. CEOS Virtual Constellations (con’t) Constellation for Ocean Surface Vector Wind (OSVW) Promote the widespread use of scatterometer-derived surface vector winds (SVW) and altimeter-derived significant wave heights (SWH) in operational marine analyses and forecasts worldwide, as a contribution to the protection of life and property at sea. Constellation for Ocean Surface Topography (OST) The implementation of a sustained, systematic capability to observe the topography of the surface of the global oceans ranging from basin-scale to mesoscale. Constellation for Precipitation (PC) To guide, facilitate, and coordinate continued advancements of multi-satellite global precipitation missions. The 23 rd CEOS Plenary I Phuket, Thailand I 3-5 November 20093

5. Generic Constellation Activities All six Constellations are engaged in various stages of activities: Collaboration in cal/val and algorithm development Agreement for timely exchange of data and products Standardization of products and formats Generation of integrated, multi-mission products and distribution from a central site Training & capacity building for both researchers and operational users Definition of requirements for future systems Harmonization of orbits to optimize observational coverage The 23 rd CEOS Plenary I Phuket, Thailand I 3-5 November 20095

6. 2010 and Beyond The 23 rd CEOS Plenary I Phuket, Thailand I 3-5 November 20096 ACC and LSI: Data Portals – recognizing the need for accessibility and interoperability – Development of a enhanced LSI Data Portal which builds upon prototype LSI Data Portal, released March 2009 – ACC Data Portal – one-year demonstration project Will serve forecasters, assessment, climate users and provide access, tools, and guidance to investigators and value-adding organizations – Both supported by WIGISS LSI: Contribution of LSI data to the Forest Resources Assessment 2010 Project LSI: Establishment of a WG on Regional Data to coordinate LSI data contribution to the Global Land Survey 2010

7. 2010 and Beyond (con’t) OSVW and OST: “Use of Satellite Wind and Wave Products for Marine Forecasting” – Dec 2009; Oostend, Belgium – Organized by NOAA and EUMETSAT, in collaboration with IOC – Other workshops to be scheduled in Developing Countries OSVW and OST: Address deficiencies in the operational utilization of observations from OSVW & OST Constellations OST: Continue to work with the altimetry community to realize the recommendations put forth in The Next 15 Years of Satellite Altimetry: Ocean Surface Topography Constellation User Requirements Document PC: ISRO & CNES have augmented ground-station coverage for Megha-Tropique to reduce data latency The 23 rd CEOS Plenary I Phuket, Thailand I 3-5 November 20097

8. The opportunity exists to more fully realize the objective of CEOS through the Virtual Constellations – Excellent start with the six existing Constellations The 23 rd CEOS Plenary I Phuket, Thailand I 3-5 November 20098 2010 and Beyond (con’t)

9. The recent OceanObs’09 Conference – attended by more than 600 oceanographers from 36 countries – suggested that CEOS Virtual Constellations be used as a means to focus space-based efforts in support of the GCOS Essential Climate Variables (ECVs) CEOS could make a major contribution to achieving GCOS Essential Climate Variables (ECVs) by encouraging the initiation of new Constellations as well as strengthening existing Constellations – Possible candidates for new Constellations Sea Surface Temperature Radio Occultation Sea Ice The 23 rd CEOS Plenary I Phuket, Thailand I 3-5 November 20099 Constellations and ECVs

10. GCOS Essential Climate Variables ECVs are required to support the work of the UNFCCC and the IPCC and thereby GEO. ECVs are technically and economically feasible for systematic observation. These variables require international exchange to access both current and historical observations. Currently, there are 44 ECVs (plus soil moisture recognized as an emerging ECV) as shown in the following table. Additional variables required for research purposes have not been included.
