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
• Mikes 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

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?
