1. WMO Architecture for Climate Monitoring from Space Update for ICG WIGOS Jérôme Lafeuille (OBS/SAT/C/SBOS) Stephan Bojinski (OBS/SAT/SO/SUP) WMO; OBS/SAT (SBOS)

2. WMO Two actions in the WIGOS Implementation Plan  Collaboration  2.1.2: Develop collaboration framework for the Architecture for Climate Monitoring from Space  Design, planning and evolution  3.1.2: Develop the Architecture for Climate Monitoring from Space, focusing on 4 GFCS priorities

3. 2.1.2 Collaboration  Ad-hoc working team established in 2012  Strategy document published in Feb 2013 Strategy document  Joint CEOS-CGMS Working Group on Climate approved by CGMS (July 2013) and CEOS (Nov. 2013)  WMO as both CGMS Member and CEOS Associate is an active member of the Joint WG (W. Zhang, J. Lafeuille/S. Bojinski)  First meeting planned on 5-7 March 2014 CEOS: Committee on Earth Observation Satellites CGMS: Coordination Group for Meteorological Satellites Strategy towards an Architecture for Climate Monitoring from Space CEOS, CGMS, WMO

4.  The ToR of the joint CEOS-CGMS Climate WG include (in summary):  Maintain a view of available Climate Data Records from satellite obs  Foster best use of available data to deliver further CDRs e.g. through calibration, reprocessing initiatives  Optimize planning of future satellite missions and constellations  Expected outcomes:  Definition/implementation of Climate Monitoring Architecture for space obs  Review and assessment of CDR generation, compliance to GCOS…  Advice to CEOS and CGMS on response to UNFCCC, IPCC, GFCS 2.1.2 Collaboration (continued)

5. Conceptual stage: Architecture Pillars with logical representation of data flows and dependencies Traceable to GCOS Guidelines and GCOS Climate Monitoring Principles 3.1.2 Design, planning and evolution

6. WMO contribution adresses both ends: Space Segment analysis building on OSCAR/Space and related assessments Identify CGMS missions to support FCDRs and derived ECVs in a sustained manner (with ET/SAT) Encourage CGMS commitment on these missions Highlight gaps and prompt actions Satellite data use scenarios in GFCS priority areas Identify user requirements for climate services and infer product requirements (with ET-SUP) Use case studies in GFCS literature (“Climate ExChange”) Highlight gaps and prompt actions
