Transcription

1 World Meteorological Organization Global Atmosphere Watch Workshop on Measurement-Model Fusion for Global Total Atmospheric Deposition (MMF-GTAD) February 28 March 2, 2017 World Meteorological Organization Geneva, Switzerland Organized by The Global Atmosphere Watch Scientific Advisory Group for Total Atmospheric Deposition (GAW SAG-TAD)

2 Background: Global Assessment of Precipitation Chemistry and Deposition Measurement ( ) Model (2001 Ensemble Mean) (Vet et al., Atmospheric Environment 93 (2014) 3-100)

4 Workshop Objectives To review the state-of-the-science and establish a GAW project on Measurement-Model Fusion for Global Total Atmospheric Deposition To explore the feasibility and methodology for producing global maps of atmospheric concentrations of gas and aerosol species as well as wet, dry and total deposition To meet the needs of policy-makers, science programs and client communities including human health, ecosystem health, biogeochemical cycling, biodiversity, agriculture, climate change

5 Participants Experts in: Human health Ecosystem health International Programs: health (WHO), nitrogen (INMS) and phosphorus (GESAMP) Measurement-model fusion, data assimilation, objective analysis Global and regional modelling and evaluation Data management, analysis and distribution Satellite observations and applications to human health and deposition Ground-based gas, aerosol and deposition measurements Wet and dry deposition WMO WMO/GAW Scientific Advisory Groups and Expert Teams

6 Workshop Structure Keynote speakers Policy and Science drivers/clients (international biodiversity, critical loads, nitrogen, human health) Science presentations and panel discussions Current MMF-TAD projects and activities worldwide Surface and satellite measurements Regional and global modelling, evaluation and comparability (HTAP2, AQMEII3, MICS3, ECMWF/Copernicus) Breakout and Plenary Sessions Is it possible to create a MMF-GTAD project How, what, who, when and where?

7 Major Outcomes Unanimous agreement to establish a formal WMO/GAW MMF-GTAD Project Focus on S, N, O 3 A three phase project: Phase 1 Short Term. MMF of existing 2010 ensemble global model results with existing data sets (HTAP, AQMEII) Phase 2 Medium Term. Stitch together MMF-TAD existing and new regional/global maps (Canada, USA, UK, Sweden, Norway, Asia, Europe) to produce global maps + a journal article Phase 3 Long Term. Ongoing operational re-analysis using data assimilation (ECMWF/Copernicus) Buy-in of all major modelling groups, WMO Scientific Advisory Groups, measurement groups, policy and science drivers WMO/GAW Workshop Report (to be posted on Roadmap to the Future Report

8 Clients Internationally World Health Organization (WHO Air Quality Guidelines, Global Burden of Disease Study) UN Convention on Biodiversity (Aichi Target 8 Indicators) UN Sustainable Development Goals (Targets and Indicators) Biodiversity Indicators Partnership UN Framework Convention on Climate Change Global Partnership on Nutrient Management Climate and Clean Air Coalition International Nitrogen Management System International Nitrogen Initiative UNEP Global Programme of Action for the Protection of Marine Environment from Land-Based Activities UNECE Convention on Long Range Transboundary Air Pollution ICP Forests, ICP Waters, ICP Modelling and Mapping Critical Loads

9 Alignment with NADP/TDEP Global model comparisons/ensembles: variability of models Stitching of regional products: US-Canada Air Quality Agreement Potential use of TDEP scripts/routines for new regions (Europe, Asia)? Global dataset compilations (2010, ~2015) Measurement breakout recommendations: Increased acceptance of passive sampler data and potential development of DQOs (by GAW); organic nitrogen Focus on model development of dry deposition schemes, land use New methods for satellite data assimilation
