Observing System Status- Brief Overview

1. 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

2. 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!

3. 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

5. Observing System Monitoring Center Near-real-time tool for system statistics and data • Sort by: • Platform type • Variables being sampled • Time frame • Contributing Country • Drill down for platform metadata and real-time data. Test Version 2.00 beta: www.jcommops.org/network_status

6. Status of the System 6279 platforms globally. 2950 U.S. platforms. ( One day snapshot of surface platforms reporting

7. Coming Soon:Direct link to performance monitoring GOOS Requirement for SST: 5x5 grid

8. Tropical Moored Buoys • TAO/TRITON sustained • PIRATA Extensions implemented • Indian Ocean Array getting started

9. Argo Profiling Float Array 2849 active floats

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

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

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

14. 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 Sites where Tsunami and Climate plans overlap -- potential for coordination Sites where Climate missions already deploy tsunami buoys routinely

15. 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?

16. “KNOWN” FUTURE ALTIMETRY MISSIONS In orbit End of life Approved Planned/Pending approval GFO IPY Data gap ERS-2/RA Sentinel-3 ERS-1 ENVISAT/RA-2 SARAL TOPEX/Poseidon Data gap? Data gap? Jason-3? Jason-1 Jason-2 CNES/EUMETSAT/NASA/NOAA signedLetter of Agreement for Jason-2 CRYOSAT-2 GODAE
