Current JCOMM contributions to WIGOS
• See Doc 6(1)_JCOMM• Addressing legacy recommendations of JCOMM Pilot
Project for WIGOS• Creation of Regional Marine Instrumentation Centres
(RMICs)• Establishment of an International Forum for Users of
Satellite Data Telecommunications (Satcom Forum)• Work programme in support of WIGOS has resource
implications of about USD100k per year

Current JCOMM contributions to WIGOS• International co-ordination well established• Real-time monitoring and support to operators• Promotion of best practice
– Metadata availability– RMICs established in USA and China; Morocco next– Update of Manuals and Guides
• Capacity development• Transition to climate-quality observations• Preparatory workshop for Satcom Forum• Pilot Projects
– New sensors, new ECVs, platforms and standards– Interaction with satellite community– Communications technologies

Capacity Development

Interaction with satellite community:Group for High Resolution SST (GHRSST)• GHRSST use drifter SST for validation• New drifter spec agreed that meets their needs• Pilot ‘upgrade’ programme launched

Climate Issues - Global Sea Level Rise(courtesy of Ed Harrison, NOAA PMEL)
• The satellite + tide gauge analysis tells us the recent 20 year trend is ~3mm/yr, with interannual variability
• Our upper ocean heat content analyses are not able to explain the observed trend
• Where is the missing heat and/or mass?
• Deeper Ocean? Ice? Land water changes? Are ocean processes key to future rate?

Future JCOMM contributions to WIGOS
• Closer interaction with satellite community– Pilot project for in situ surface vector winds
• Roll-out of climate-quality observations– Ocean heat content and sea-level rise
• Deep Argo
• Sub-sea cables (ITU/IOC/WMO JTF): dual use for tsunami warning
• Improved sea-level network: dual use for tsunami warning
• Implementation of Satcom Forum• Biogeochemical observations• Composite network design
– OSSEs– Better metrics of system performance
