  1. ATMOSPHERIC CHEMISTRY APPLICATIONS WORKSHOP20-21 January 2004, ESTEC Tasks of Working Groups by Albert P H Goede Objective of the Workshop User Consultation on present and future needs for atmosphere chemistry observations to serve as input for the Definition of Integrated Global Observation System, notably the satellite component work to carried out in the ESA CAPACITY project

  2. Working Group Themes/aspects Climate Change Long-term monitoring & trends in atmospheric composition in relation to chemistry-climateinteraction, observation UTLS, natural variability, providing input to IPCC assessments Montreal Protocol Monitoring and Verification Kyoto stratospheric ozone trend and evolution, surface UV exposure, GHG emissions inventories time series, quantification, global completeness, providing policy support TroposphereCleansing power of atmosphere and trend Composition/Chemistry of the free troposphere Air Pollution CLRTAP (Convention Long-Range Transport), EC directives on air quality, policy support Forecasts ozone hole and surface UV, chemical weather, improvement of NWP, regional and city scale model input, aviation management Atmospheric Chemistry Applications Workshop ESTEC 20-21 January 2004-

  3. User input required • User Information Needs specify data products with region/global, spatial resolution/range, temporal resolution/averages, time series etc • User Segment regional environmental agency, weather service, climate change agency etc • Policyfoundation Kyoto, CLRTAP etc • Science review what are the underlying science issues, what do we know, what is still uncertain, etc • Strategyfor Integrated Observation System What infra structure is there on ground, in situ, in space and how to improve or fill gaps. What can be achieved in 2, 5, 10 years time and how to go about it Atmospheric Chemistry Applications Workshop ESTEC 20-21 January 2004-

  4. Working Group Composition • WG1Air Quality Monitoring (chair Boucher/raporteur Monks) ETCACC RIVM+NILU, ADEME, ITC, EMPA, EPA, GMES- Daedalus, CERMES • WG 2 Montreal, Kyoto Protocol Monitoring (ch Barrie, rap Raes) WMO, NILU, GMES-GATO, JRC-IES, RIVM-UV • WG 3 Climate Chemistry (chair van Weele, raporteur Kerridge) DLR-IAP, KNMI, JRC, KfA Julich, SPARC, research groups • WG 4 Tropospheric Chemistry (chair Bovensmann, rap Krol) MPI-Hamburg, U Heidelberg, IGBP-IGAC, ACCENT, LISA, other research groups • WG 5 Forecasting (chair Peuch, raporteur Fishman) Meteo-France, DWD, DMI, KNMI, INERIS, LISA, VITO Atmospheric Chemistry Applications Workshop ESTEC 20-21 January 2004-

  5. WG template (Michiel van Weele) • User Needs • User Segment • Policy foundation • Science review • Strategy Atmospheric Chemistry Applications Workshop ESTEC 20-21 January 2004-

  6. How to proceed • First draft: End of Workshop January 2004 • Input to CAPACITY PM1, 4 February 2004 • Derive observational requirements • Assess how well these requirements are met by existing and by planned space missions and ground and in-situ observations. What is missing. Per application and per System. • Consolidated set of high level user requirements for Integrated Global Observation System • CAPACITY PM2, April 2004 • Feed back from Users at Mid term review 17/18 June 2004. Strategy 2, 5, 10 years. Priorities. Atmospheric Chemistry Applications Workshop ESTEC 20-21 January 2004-

  7. CAPACITY Definition of a global observation system, integrating space and in-situ observations, that responds to (end-)user requirements. Tool for integration is data assimilation into models. • To define (end-)user requirements for individual applications (Task 1). User consultation meeting. • Relate these to observational requirements (Task 2.1) • How well are the user requirements met by the existing and approved mix of satellites and in-situ observation systems? What is missing? (Task 2.2 and Task 2.3 for each application) • How well doescombination of missions (existing, planned and conceptual) meet individual applications? (Task 3) • The time frame projected is the period 2010-2020, concurrent with operational use of MetOp , MSG and NPOESS. Atmospheric Chemistry Applications Workshop ESTEC 20-21 January 2004-
