4. What is going on in SISS WG?
Exchange of information during side meetings during conferences (e.g. EGU)
What’s next? Some ideas:
PI-MEP (Roberto)
Need for scientific studies (Bill)
Low Frequency Passive Microwave User Requirement (Jacqueline)
Other???

5. Low Frequency Passive Microwave User Requirement Consolidation Study
ESA funds (=> user meeting + report) – PI: Y. Kerr – CESBIO
Ocean scientists: J. Boutin, N. Reul, A. Turiel
Ongoing task :
Specify Application areas
and for each Application area:
Required/Useful/Optimal :
[Spatial resolution/Temporal resolution/Accuracy]

6. SISS WG to help in defining these specifications?
