Observing System Status- Brief Overview Will post PPts from Mike Johnson and from Eric Lindstrom from the annual review of the NOAA Climate Observations Program to provide more details on recent NOAA and NASA perspectives Mike’s JCOMM Obs Coordination PPt is available from JCOMM web site

Keeping it going There has been some progress in some nations toward sustaining in situ and satellite observing efforts. However most efforts are still supported via research agency funding and the efforts of research oceanographers Demonstrations of effectiveness of system will be a continuing need INDICES!

In Situ System Particular progress w. real time Tide gauges and pCO2 Incremental progress in some other elements Increased awareness of challenges of maintaining global distribution of both surface drifters and float Some historical data issues w. XTBs and some Argo floats New GOOS coastal technical panel

GCOS Climate Reference Network of Tide Gauge Stations GEO-located Establishing the GCOS subset of GLOSS Climate Reference Stations By the end of 2007 most of the 170 Climate Reference Tide Gauge Stations Will Provide Marine Hazards Warning in Real Time

Deploying and maintaining 89 Ocean Reference Stations (42 now in service) NOAA Contributions Future NOAA Future NSF OOI ITF and MOVE in transition to NOAA

38% complete Measuring Ocean Carbon Sources and Sinks 1. Inventory 10-year survey 2. Ships of opportunity 3. Moored buoy time series

Sites where Tsunami and Climate plans overlap -- potential for coordination Sites where Climate missions already deploy tsunami buoys routinely Integrating tsunami buoys into GOOS (JCOMM DBCP and OceanSITES) Chilean Tsunami Buoy being deployed during a U.S. Climate mission Met sensors installed by USA (WHOI) on the Chilean tsunami buoy in October 2006

Satellite System Status Mostly status quo ante last year in terms of data available GHRSST products available CEOS response to GCOS IP has raised visibility of mission continuity issues IGOS-P merger into GEO Bigger role for China and India ahead?
