What is the Global Atmosphere Watch
Programme?

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 100 countries.

GAW is coordinated by the Research Division of WMO under the
purview of WMO Commission for Atmospheric Science (CAS)

Currently GAW coordinates activities and data from 29 Global
stations, more than 400 Regional stations, and about 100 Contributing
stations (http://gaw.empa.ch/gawsis/)

GAW Global Stations
GAW and GCOS
GCOS recognition of GAW coordinated observations:

the WMO/GAW Global Atmospheric CO2 & CH4 networks as
baseline and comprehensive observing networks of GCOS.

the WMO/GAW Global Atmospheric N2O network as a
baseline and a comprehensive observing network of GCOS.

the WMO/GAW Global Atmospheric Total Ozone network as
a baseline observing network of GCOS.

the WMO/GAW Global Atmospheric Ozone profile network
as a baseline observing network of GCOS.
How does GAW work?
NMHSs and other contributors
Observations is only one of the elements of the GAW Programme!
GAW implements end-to-end approach “from observations to products and
services”

Where/how GAW provides input
to WIGOS
1) ICG-WIGOS (Sandro Fuzzi)
2) Harmonization of network regulations, TT-WRM (Ann
R. Webb)
3) Metadata compatibility, TT-WMD (Joerg Klausen)
4) WIGOS Quality Management, TT-WQM (Rainer
Steinbrecher)
5) WIGOS Implementation Plan, TT-WIP (Emilio
Cuevas)
GAW works on the establishment of the Rolling Review of
Requirements process for Atmospheric Chemistry application area to
harmonize the observational network development with strategy for
evolution of WIGOS
Progress on Regulatory
Material (TT-WRM)

GAW observational component (as one of the WIGOS
components) is described in WIGOS Manual

GAW procedures are described in details in Technical
Regulations and WIGOS Manual (Chapter 5).

Chapter 5 includes provisions harmonized with the other
observational components of WIGOS on:
1)
2)
3)
4)
5)
Requirements (as result of Rolling Review of Requirement process)
Instruments and methods of observations
Metadata standards
Quality management
Capacity development
Progress on Metadata
compatibility (TT-WMD)


CAS deeply involved in TT-WMD defining the WIGOS
metadata standard
Work of GAW ET-WDC very much aligned with WIGOS




Discussion of WIGOS metadata standard at recent meeting of GAW
Expert Team on Data Centers in Tokyo, January 2014  overall
approval
GAW Metadata profile of ISO19115 approved; compliant with WMO
Core Metadata profile, and includes many aspects of WIGOS metadata
requirements
Notion of a “virtual GAW data center” with interoperable WDCs was
approved  strategy document planned
Meanwhile, GAWSIS continues to serve as catalogue of GAW stations
and to connect WDCs and related archives.
Slide from Joerg Klausen
Opportunities for GAW within WIGOS




improved visibility of observational requirements to
Members (as requirements for all application areas are
summarized in WIGOS requirements database)
promotion of the GAW observational network extension
(encouraging Members to perform atmospheric
composition measurements at meteorological & synoptic
stations)
promotion of harmonized approach to Quality Assurance
(e.g. reporting of harmonized quality flag)
promote exchange of meteorological information for the
stations performing atmospheric chemistry measurements
(through cross-reference table of code)
