1. Makoto Kajii SIT Chair 2010 – 2011 5 th Annual Report on CEOS Implementation of the GEOSS Space Segment - Virtual Constellations: 2011 Progress & requests to CEOS Agenda Item 6 The 25 th CEOS Plenary – Nov 8,9

2. GEO task, AR-09-02a “Virtual Constellations”  Observations from a virtual constellation would provide better temporal, spatial, and spectral resolution and related data management and dissemination.  A series of virtual constellations are in definition by space agencies, in consultation with user communities within the CEOS framework, each addressing key GEOSS observation gaps in the process.  SIT Chair confirms each VC’s progress by regular Teleconference. Virtual Constellations

7. Additional Comments from VC leads are invited

8. The 25 th CEOS Plenary – Nov 8,9  SIT-25 in Tokyo (April, 2010) Discussed significance of the long term observation  Plenary in Rio de Janeiro (October, 2010) Discussed CEOS Portals and GCI support  February WS in Arlington (February, 2011) Discussed CEOS Metadata contribution to GCI Clearinghouse through IDN  SIT-26 in Frascati (May, 2011) CEOS Portal Study progress report Agreed IDN support for GCI Discussed VC contribution to WG Climate Past discussions on VC

9. The 25 th CEOS Plenary – Nov 8,9 " CEOS Agencies encouraged to accumulate their datasets and information resources with the GEOSS Common Infrastructure, GCI." Data Meta-data GCI CEOS IDN VC Portal VC Data Portals in support of GCI C ommunity USERS Data Meta-data GEOSS USERS GEOSS USERS

10. The 25 th CEOS Plenary – Nov 8,9 Scientific requirement coordination by user community Implementation User Community (GEO CoP) CEOS Comprehensive Observation Requirement Integrated Observation Plan Request Data Coordination Model for Global Observation Study “Data Providing Plan and System” must be included

11. The 25 th CEOS Plenary – Nov 8,9  To participate in drafting of Integrated Observation Plan of CEOS Collaboration with WG Climate will be useful model for Carbon and Water  To articulate data providing plan and system of each VC which need to be defined in the Integrated Observation Plan  To develop and operate the data portal in accordance with the plan specified in Integrated Observation Plan The VC data system in GEOSS era needs to provide data through on line base VC roll in the Coordination Model

12. The 25 th CEOS Plenary – Nov 8,9 TRMM TMI Aqua AMSR-E Geostationally Meteorological Satellite NOAA AMSU DMSP SSM/I, SSMIS In-situ data On-line Data Access Example of data providing plan and system Water Data Portal Application Use (Global Rainfall Map) Application Use (Global Rainfall Map) Simulation output Application (Global Rainfall Map) Application (Global Rainfall Map) VC data

13. The 25 th CEOS Plenary – Nov 8,9 Summary  Status of VCs are going well in general except issue of Chinese and Russian satellite data access.  GCI support through IDN was coordinated and VCs are encouraged to promote the support.  The Coordination Model is applicable not only for GCOS ECV case but also for Carbon, Water and so on.  VCs roll in the Integrate Observation Plan is to articulate the VC data providing plan and system.  Data Providing in GEOSS era exchanges data through online.
