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 GAW2005 Workshop 14-16 March 2005 WMO Geneva

Motivation
 Air Pollution Forecasting, Health Effects, Long
Range Transport and Deposition Effects
 Improved Weather Forecasting:
By Including Aerosols, Ozone and Reactive Gas
Observations
 Climate, Climate Change and Climate Prediction
 Oxidizing Power:The Atmosphere As A Waste
Processor. Key to Global Hg and some POPs
 Stratospheric Ozone Depletion and Surface UV
Enhancement: Are Halocarbon controls working?
Effects of UV on biosphere?

Information from GAWSIS provided by WOUDC (valid May 2005).
Colors: most recent data (grn) <1 yr ago, (ylw) <2 yrs ago, (red) < 3 yrs ago, (blu) >3 years ago.
Color saturation is proportional to data capture. Point area is proportional to total length of record.

Integrated Global Atmospheric
Chemistry Observation (IGACO) System
An IGOS theme
Objectives:
1.
implemented by WMO
2.
Observations
Satellite
IGACO System
3.
To ensure accurate, comprehensive global
observations of key atmospheric gases and
aerosols;
To establish a system for integrating groundbased, in situ and satellite observations using
atmospheric models;
To make the integrated observations
accessible to users.
An international process:
Panel of 19 experts from 12 countries and
independent reviewers from 7 countries.
