An Integrated Global Atmospheric Chemistry Observations Strategy IGACO &

WMO GAW and GEOSS

Hennie KelderProfessor University of Technology of Eindhoven

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) International Group of Funding Agencies for Global Change Research (IGFA)

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

• ……

Objectives:1. To ensure accurate, comprehensive

global observations of key atmospheric gases and aerosols;

2. To establish a system for integrating ground-based, in situ and satellite observations using atmospheric models;

3. To make the integrated observations accessible to users.

An international process:

Panel of 19 experts from 12 countries and independent reviewers from 7 countries.

IGACO TARGET VARIABLE LIST

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 WMO’s

Atmospheric Research and Environment Programme

(AREP) department under the Commission for

Atmospheric Science (CAS) and its Working Group on

Environmental Pollution and Atmospheric Chemistry.

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
