1. CEOS SST-VC Status Kenneth S. Casey and Anne O’Carroll on behalf of the SST-VC members CEOS VC/WG day 16 September 2015

2. 2 The SST-VC spent the last year focusing on a narrower number of activities specifically identified in the CEOS Work Plan: SST-VC meeting #4 took place at ESA-ESTEC on 24 th July 2015 (following GHRSST-16). Supported invitations to NSOAS and CMA China (CMA sent regrets), ROSHYDROMET (Russia, no reply). ISRO (observed SST-VC #4) and further invitation to be sent. Satellite Oceanography User Workshop, Melbourne, 9-11 th Nov 2015 https://www.ghrsst.org/ghrsst/Meetings-and-workshops/satellite-oceanography-user- workshop/ Possible SST-VC presentation to IOVWST in Sapporo, May 2016 Main Activities over last year

4. 4 SST-VC developing a whitepaper on the next generation SST Virtual Constellation, including necessary on-orbit assets, measurement methods (MW and IR, Geo and Polar), climate/NWP applications, fiducial reference measurements, and data management systems Whitepaper Status: - Draft in preparation and book captain identified - Review of progress took place at GHRSST-16 (July 2015) - Publication targeted for later in 2015 Progress on White Paper

5. 5 Inputs to white paper include three priorities of the optimisation of the SST constellation: 1)Provision of dual-view reference IR radiometer -> Copernicus Sentinel-3 SLSTR planned for November 2015 2)Complete latitudinal coverage of IR radiometers from geostationary orbit -> ISRO and hopefully CMA 3)Redundant capability of passive microwave radiometers -> More progress needed. Contact with NSOAS (HY-2); ISRO -> Considerations by space agencies -> Need to ensure continuity of existing capability -> How can the coordination of agencies be facilitated to ensure continuity and redundancy of passive microwave radiometers? Priorities for optimisation of the SST constellation
