1 WMO CAS achievements and challenges within WIGOS Sandro Fuzzi National Research Council, Italy WMO: Research Dept.

2 What is the Global Atmosphere Watch Programme?  WMO/GAW was established 1989 by merging GO 3 OS 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 30 Global stations, more than 400 Regional stations, and about 100 Contributing stations (http://gaw.empa.ch/gawsis/) ICG-WIGOS Fourth Session, February

3 GAW Steering Bodies  Scientific Steering Committee of the Open Programme Area Group on Environmental Pollution and Atmospheric Chemistry (EPAC SSC)  Scientific Advisory Groups (SAGs)  Ozone  Greenhouse Gases  UV Solar Radiation  Reactive Gases  Precipitation Chemistry/to be converted to SAG on Total Atmospheric Deposition  Aerosols  SAG GURME (urban pollution)  Expert Teams:  World Data Centres  Near-Real-Time Chemical Data Tansfer/ to be converted to ET on Integrated Atmospheric Composition Products 3 ICG-WIGOS Fourth Session, February 2015

4 Operational support functions  GAW observational and data infrastructure is 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 ICG-WIGOS Fourth Session, February

5 GAW Station Information System GAWSIS Online - comprehensive information on all GAW stations Database Search / Update Inventory / Audit (Supported by Switzerland) GAWSIS will become 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, February

6 CAS achievements within WIGOS (1)  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. 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. 6 ICG-WIGOS Fourth Session, February 2015

7 CAS achievements within WIGOS (2)  Task Team on Observational Requirements and Satellite Measurements as regards Atmospheric Composition and Related Physical Parameters  TT met in November 2014  TT defined three application areas to cover “atmospheric chemistry”  TT looked at the other application areas which do exist and which use atmospheric composition  TT will review user requirements in different application areas within RRR process (in collaboration with the “owners” of the other application areas)  TT will help establishing the RRR process as integrated part of GAW within the WIGOS framework. 7 ICG-WIGOS Fourth Session, February 2015

8 CAS achievements within WIGOS (3)  Current application area “Atmospheric Chemistry” to be 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) 8 ICG-WIGOS Fourth Session, February 2015

9 CAS achievements within WIGOS (4)  The Task Team started the RRR process and will populate the OSCAR data base for the three application areas  The OSCAR Excel sheet in progress: q.html q.html  The process is in progress and engages the CAS SAGs and SSC  SAGs are discussing the application areas and the parameters needed for the applications and will continue filling out the OSCAR sheet of user requirements for the parameters that fall in their domain 9 ICG-WIGOS Fourth Session, February 2015

10 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 10 ICG-WIGOS Fourth Session, February 2015

11 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) 11 ICG-WIGOS Fourth Session, February 2015
