WHO questions
European ORGANISATION for the EXPLOITATIONof Meteorological Satellites (EUMETSAT).
Or
Who is organised? The users. (MET services)Who is exploiting the satellites? The users.
EUMETSAT is doing (with partners) user-driven satellite programmes EUMETSAT is doing more and more oceanography

Observational network design
The fundamental and most difficult issues in discussion of observations of any kind are all related to the two questions:
1. What is one trying to observe?
2. How well does it have to be done?
A consequent, but less fundamental, third question is:
3. What is the current capability and in what ways does it remain inadequate?

Virtual Constellation
Virtual: Existing or resulting in essence or effect though not in actual fact, form, or name
Constellation: a group or configuration of ideas, feelings, characteristics, objects, etc., that are related in some way.
1. Striking realism in it.2. Is International Collaboration3. Is Captured programmatically

WMO / CGMS : Ocean Considerations
• Several coordination areas are well catered for outside CGMS, in particular by CEOS Virtual Constellations
• Encourage the CEOS Virtual Constellations to submit papers to CGMS on relevant operational matters with appropriate recommendations to CGMS
• Strengthen the link to JCOMM, in particular the Cross Cutting Task team on Satellite Data Requirements.
• Ocean is considered explicitly in climate activities and handled by the CEOS-CGMS Joint Working Group, and the increased capabilities of the next generation GEO satellites for ocean applications will also be addressed in this context.

SST-VC Background
• GHRSST formed in 2000 and operating successfully, so no desire to duplicate
• Instead, SST VC created to serve as a bridge between CEOS and the existing Group for High Resolution SST (GHRSST)
• Over 60 GHRSST products, flowing through international data management framework
• SST-VC brings CEOS requirements to GHRSST• For example, WGISS requirements for CWIC/IDN
• GHRSST feeds requirements to space agencies via SST-VC• Scientific developments• Product generation requirements• Constellation requirements (draft paper)

Final Remarks/Thoughts
• Virtual constellations as a program they virtual but as missions addressing user needs they are real.
• GOV is Virtual Constellation for the science of Global Operational Ocean Model Suites.
• Let’s remember that GHRSST started as a GODAE project.
• User-driven ocean satellite missions => You are in the driver seat. Hence towards space agencies
Less: “Great that you guys do this for us”More: “You should do this and this!” Carl Wunsch,
OceanObs 2009
Less: user advice more: user requirements
• Support further globalisation
