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 total atmospheric deposition
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 the observational component of GAW is based on activities at 30 Global stations, more than 400 Regional stations, and about 100 Contributing stations (http://gaw.empa.ch/gawsis/)

supported by Members operating central facilities: World Calibration Centres Central Calibration Laboratories World Data Centres
Ozone and UV Solar Radiation Aerosols Greenhouse gases Precipitation chemistry The World Data Center for Remote Sensing of the Atmosphere
GAW Station Information System (GAWSIS)
This has created a sustainable system
GAW Station Information System
GAWSIS Online - comprehensive information on all GAW stations
• Database • Search / Update • Inventory / Audit
(Supported by Switzerland)
• GAWSIS became a part of OSCAR data base (with observational capabilities)
• GAWSIS is being reviewed at the moment and works toward implementation of the WIGOS meta data standard
ICG-WIGOS Fourth Session, 17-20 February 2015 6
CAS achievements within WIGOS (1) CAS deeply involved in Task Team – World Meta Data 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.
SSC endorsed in June 2014 the Atmospheric Composition Vocabulary Task Team (already operational) which looks at the metadata related to atmospheric composition in a broader sense and feeds this information back to ET-WDC.

Evolution of the GAW observational networkUsing the Rolling Review of Requirements (RRR)Process according to WIGOS Manual:
(i) a review of technology-free requirements for observations, within an area of application covered by WMO programmes and cosponsored programmes;
(ii) a review of the observing capabilities of existing and planned observing systems, both surface- and space-based;
(iii) a Critical Review of the extent to which the capabilities (ii) meet the requirements (i); and
(iv) a Statement of Guidance based on (iii).
Network development should be performed in a systematic way to address specific applications
Application areas within GAW
A Task Team on user requirements for atmospheric composition and related needs for satellite measurements was formed to assist the RRR process
The broad “atmospheric chemistry” application area was substituted with more specific application areas:• “atmospheric composition forecasting”,• “atmospheric composition analysis and monitoring” • “urban services”.
Task Team develops an approach to assess user requirements.
The report of the first meeting is published (GAW Report No. 221). Second meeting of TT took place on 12-13 August 2015.
CAS achievements within WIGOS
Current application area “Atmospheric Chemistry” is split into 3 areas: Forecasting Atmospheric Composition: Applications
global to regional with stringent timeliness (NRT) Monitoring Atmospheric Composition: Applications
related to changes of atmospheric composition regionally and globally less stringent timeliness (no NRT)
Providing Atmospheric Composition information to support services in urban and populated areas: Applications targeting limited areas (with horizontal resolution of a few km and stringent timeliness requirements (air quality forecasting)

Challenges still to be addressed by CAS
GAW implementation plan is currently under development The plan will be built around applications rather than
around focal areas –> needs a lot of work to build understanding of cross-cutting applications
The plan will take WMO priorities into consideration and build around them
Major principles of network design and quality assurance (developed within WIGOS) are imbedded in GAW and will be further fostered
Outreach strategy (how to explain NMHSs the role of atmospheric composition in understanding weather and climate) should be developed
11ICG-WIGOS Fourth Session, 17-20 February 2015
Needs for improving collaboration among TCs/RAs within WIGOS
Need for recognition and support of GAW stations by NMHSs for observational network to be sustainable (long-term “cultural” and “political” improvement)
WMO assumes that communicating with National Representatives is enough to correspond with the whole national Institutions involved (not always true!)
Direct involvement of Institutions other than NMHSs needed for rationale and positive GAW contribution to WIGOS (procedures needed)
12ICG-WIGOS Fourth Session, 17-20 February 2015
GAW Implementation Plan (2015-2023) The plan concerns only implementation of the GAW Programme, WMO
Strategic Plan is taken as an overall strategy Short (focuses on the major principles, SAG specific tasks are in the
annex) Follows the concept “research enabling services” – the activities are
around application areas rather than focused on GAW parameter specific areas
More focus on modelling tools and value added products Provides clear framework for the programme implementation
concerning network design, modelling tools, quality assurance principles, data management, collaboration with the other programmes
IP builds upon the premise that atmospheric composition matters - to climate, weather forecasting, human health, terrestrial and aquatic ecosystems, agricultural productivity, aeronautical operations, renewable energy production, and more.
Example of the applications in GAW
Support of climate negotiations: IG3IS
Ecosystem services: analysis of total deposition, nitrogen cycle, deposition to the oceans/marine geoengineering
Health: sand and dust storms, urban air quality (GURME), biomass burning
Food security: atmospheric composition and agriculture
Transport security: volcanic ash forecasting
