GAW Motivation: Research conducted on atmospheric
composition accounting for the human impact on the
atmosphere enables better services
The GAW Mission

Systematic Global Monitoring of
the Chemical Composition of the
Atmosphere.

Analysis and Assessment in
Support of International
Conventions.

Development of Air Pollution and
Climate Predictive Capability

GAW Forward Planning
GAW Strategic Implementation Plan (2016-2023)
- within the context of WMO SP & CAS priorities
WMO Strategic Plan 2016-2019, which can be
summarized as «Science for service» and include:
• Disaster risk reduction
• Global integrated polar prediction system (GIPPS)
• Megacities
• Global Framework for Climate Services (GFCS)
• WMO Integrated Global Observing System
(WIGOS) and WMO Information System (WIS)

GAW – What’s Next?
Continue to improve observational systems and data
processing to:
+ allow near real-time provision of GAW data,
+ support integration of surface, vertical profile and column
datasets from different platforms to provide a unified
understanding of aerosol and gas distributions,
+ minimize gaps in the measurement networks in data-poor
regions,
+ support the service needs of megacities and large urban
complexes, and
+ to track trends and support conventions and
assessments.

Observational Requirements for GAW from a
Satellite Perspective
Our major tasks are to help GAW develop a strategy for the
integration of satellite observations of atmospheric
composition and related physical parameters into the GAW
program & oversee the RRR for atmospheric composition.
•Identify priority applications/services/products for GAW
•Review WIGOS identified application areas needing
composition information
•Review current and planned satellite mission wrt
atmospheric composition
•Discuss framework for implementing the integration of the
composition observations within the GAW SIP

Application Areas – Background (1)
WIGOS Applications:
•Global numerical weather prediction (GNWP);
•High-resolution numerical weather prediction (HRNWP);
•Nowcasting and very short range forecasting (NVSRF);
•Seasonal and inter-annual forecasting (SIAF);
•Aeronautical meteorology;
•Atmospheric chemistry;
•Ocean applications;
•Agricultural meteorology;
•Hydrology;
•Climate monitoring (as undertaken through the Global Climate
Observing System, GCOS);
•Climate applications; and
•Space weather.
•In addition, the observational requirements for WMO polar activities
and the Global Framework for Climate Services (GFCS) are also to be
considered under WIGOS.

Application Areas – Background (2)
The IGACO document identified key
research applications in atmospheric
chemistry to be:
•air quality;
•oxidizing capacity;
•stratospheric ozone; and
•coupling atmospheric chemistry and
climate.

Application Areas – Background (3)
CAS-16, which identified six emerging
areas:
•high impact weather;
•water;
• Integrated Global Greenhouse Gas
Information System (IG3IS);
•aerosols;
•urbanization; and
• new technologies, including geo/climate
engineering.

GAW SIP – “Research Enabling Services”
SSC initially identified priority services as those related to
climate, high impact weather, urban (air quality/health),
ecosystems, and support of conventions.

In addressing those priorities, GAW can contribute for
example:
Through observations, analysis and prediction of pollution
episodes due to extreme weather events, like heat waves, or
forest fires
Through information on short-lived climate forcers in polar
regions (including aerosol)
Through megacities activities addressed by GAW and building
upon GURME
Through global observations of long-lived greenhouse gases
and aerosols, that can be used as a tool for climate mitigation,
which goes together with adaptation
Through integration of different spatial and temporal scales
that can be considered as a contribution to WIGOS

GAW – What’s Next?
Advance observations and analysis of
chemical constituents of the
atmosphere and UV radiation to help
reduce environmental risks to society
from high-impact weather and air
pollution, and to mitigate the impacts
of, and adapt to, changing climate.
