Why GHRSST ?
GHRSST IX (2008): “To develop and nurture cooperation and progress at the world scale in the subject area of satellite Sea Surface Temperature”

• Polar infrared has high accuracy & spatial resolution • Geostationary infrared has high temporal resolution• Microwave Polar orbiting has all-weather capability
GHRSST Builds on EO complementarities…
DataMerging
• In situ data provide reality in all weather conditions

3. GHRSST in the international landscape
GHRSST = well linked to the national and international space agencies, Met-offices, and major research institutes (e.g. Navoceano, NOAA)
GHRSST interaction with NASA SST Science Team, ESA CCI, MyOcean, Australia, Japan,
New: South Korea, Brazil, Canada, China, India .
Links to CEOS, GCOS, WMO, JCOMM, WCRP, OceanView, ET-OOFS, …

Summary1. GHRSST mission: to provide SST to operational
users and a to a massive science community
2. GHRSST priority research: uncertainty estimates, Sensor Specific Error Statistics
3. Research issues: variability in the upper ten metres cloud detection, long-term stability
4. Users: which SST should they be provided with ?
