What Is IGOS?A Consortium of 13 Partners Formed
in 1999 with a secretariat that rotates lead
every 2 years. They meet regularily with CEOS

• The IGOS Partners include the
• Global observing systems
• Global Climate Observing System (GCOS)
• Global Ocean Observing System (GOOS)
• Global Observing System (GOS) of the WMO
• Global Atmospheric Watch(GAW) of the WMO
• Global Terrestrial Observing System (GTOS)
• Sponsors of the global observing systems
• World Meteorological Organization (WMO)
• U.N. Educational, Scientific, and Cultural
  Organization (UNESCO)
• U.N. Environment Programme (UNEP)
• Intergovernmental Oceanographic Organization
  (IOC)
• International Council for Science (ICSU)
• Food and Agriculture Organization (FAO)
• Committee on Earth Observation Satellites( CEOS)
• includes all national and regional government
  agencies with an Earth observing satellite system
• Global change research programs
• International Geosphere-Biosphere Programme
  (IGBP)
• World Climate Research Programme (WCRP)

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)
• Land

Integrated Global Atmospheric Chemistry
Observation (IGACO) System

• Objectives
• To ensure accurate, comprehensive global
  observations of key atmospheric gases and
  aerosols
• To establish a system for integrating
  ground-based, in situ and satellite observations
  using atmospheric models
• To make the integrated observations accessible to
  users.

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.

WMO GAW What is it?

• The Global Atmosphere Watch programme of WMO
• Established in 1989 by merging the Global Ozone
  Observing System (GO3OS) and Background
  Monitoring of Air Pollution (BAPMoN) programmes
• Coordinated by the Environment Division of WMOs
  Atmospheric Research and Environment Programme
  (AREP) department under the Commission for
  Atmospheric Science (CAS) and its Working Group
  on Environmental Pollution and Atmospheric
  Chemistry.

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

Recommendations from IGACO, WMO GAW, GEO
Summit Short term Planning and initiation of a
coordinated satellite system compromising both
LEO and GEO instruments complemented by
non-satellite measurement network for air
quality and climate Beyond 2014 Provide an
operational network of the appropriate
combination of LEO and GEO satellites with
adequate coverage and time resolution TROPOMI is
fully in line with the recommendations of
IGACO, WMO and GEOSS to be implemented as LEO
component and as a precursor for sentinel 5 for
atmospheric chemistry
