What Do These Systematic CO2 ObservationsHave In
Common?
Satellites- not originally dedicated SCIAMACHY
- dedicated and future GOSAT, OCO
Observations All Sources

• All measure CO2 (total column, vertical profile,
  surface in situ)
• Each have own data centre(s)
• Each have own quality assurance programmes
• Missing a total column network.
• Currently not well coordinated with each other

Integrated Global Observing Strategy (IGOS)
Partnership

• Themes
• Ocean
• Global Carbon Cycle (IGCO)
• Global Water Cycle (IGWCO)
• Geo-Hazards
• Atmospheric Chemistry (IGACO)
• Coastal (incl. Coral-Reef)

What is GAW?

• WMO/GAW was established 1989 by merging GO3OS and
  BAPMoN.
• GAW focuses on global networks for GHGs, ozone,
  UV, aerosols, selected reactive gases, and
  precipitation chemistry.
• GAW is a partnership involving contributors from
  80 countries.
• GAW is coordinated by the Environment Division of
  WMO/AREP.
• Currently GAW coordinates activities and data
  from 23 global stations, 637 regional stations,
  and 19 contributing and associate stations

The GAW Mission

• Systematic Global Monitoring Of Chemical
  Composition of the Atmosphere.
• Analysis and Assessment in Support of
  International Conventions.
• Development Of Air Pollution and Climate
  Predictive Capability

The Role Of The World Meteorological Organization
(WMO)

• As the lead agency designated by IGOS to
  implement IGACO, WMO shall use its unique
  international experience, programmes and
  partnerships to build a generally accepted global
  plan and to promote implementation through
  bottom-up research efforts at the national and
  regional level.
• IGACO builds on GAW, other WMO programmes and
  partnerships. It bridges surface-based, aircraft
  and satellite observations to the weather
  forecast and modelling research community.
