9. WIGOS-ICG 18/03/20139 Instrument data End-to-end Architecture Requirements  Service requirements related to e.g. Agriculture & Food Security, Water, Health, DRR applications (4 GFCS priority areas) … …need translation into product / observation / instrument requirements: Observation (ECV) Climate Product Service level CEOS data levels Level 2/3 Level 1/2 Level 0; Instr design

10. WIGOS-ICG 18/03/201310 Requirement translation process  The WIGOS RRR addresses well the « observation requirements » for geophysical variables but…  …no systematic process in place for service-level requirements (e.g., “length of dry spell”, “number of days with PM10 exposure above 50 μg/m3”)?  Can current geophysical variable-based approach capture socio-economic data (e.g., population density; crop yield; value of infrastructure)? Product level Service level

11. WIGOS-ICG 18/03/201311 Outcome of CGMS-40 WG III on architecture  CGMS should evaluate the CGMS baseline in the light of the architecture strategy and its logical view  Relevant assets will populate space segment part of the physical architecture as « Potential capabilities to support ECV products”  Identify gaps from the space segment end - and scenarios to address them

12. WIGOS-ICG 18/03/201312 Gap analyses from both ends GAPS ? Space Segment Analysis Potential to support ECV production CEOS-CGMS-WMO ECV Inventory Actual ECV production and Climate Records Building on OSCAR/space, CEOS/MIM, GCOS Sat Sup, WMO ECV Gap Analysis, etc

14. WIGOS-ICG 18/03/201314 Conclusions  GFCS partnership should be used to help  Collect climate service requirements and translate these into product/observation requirements  Some observation requirements go beyond the GCOS ECVs (e.g., phenology; socio-economic)  The Architecture is an end-to-end approach going beyond the observation function  Currently analyzed from the « product » end  Space-based observation capabilities should also be evaluated from the « sensor » end  Unique role of WMO should be clarified in the future governance scheme
