EUMETNET WG-ENV Activities to support Network of Atmospheric Services in GMES

1. EUMETNET WG-ENV Activities to support Network of Atmospheric Services in GMES Sylvain Joffre Finnish Meteorological Institute POB 503 Helsinki, Finland EIONET- LaRochelle, 26-27.10.2006

2. EUMETNET / WG-ENV (1997) Objectives: - To improve understanding and co-operation between Members in the environmental area; - To develop proactive co-ordinated relations with the EEA and other environmental organisations. Implementing Activities: • Organise exchange of information and know-how between Members related to measurements and forecast in the environmental domain; • Recommend practices and propose EUMETNET Programmes that would allow all European citizens to benefit from the best possible meteorological information pertaining to the environment (e.g., AQ forecasting); • Maintain liaison with the EEA to serve its meteorological needs, and promote the European NMSs as providers of information and services to EEA • Enlist the support of EEA for EUMETNET actions in favour of the environment; • Maintain liaison with relevant COST Actions and other international activities. EUMETNET - EEA MoU signed on 4 September 1998.

3. WG-ENV Support to GMES Atmospheric Service • WG-ENV activities in support of the GAS • Workshop with EEA (April 2005): indication of substantial interest in collaboration of NEA’s and NMS’s in creating a real-time service • Cooperation with GEMS and PROMOTE in identifying needs, challenges, partners, etc. • Recommendation of EUMETNET Council (Oct 2005) that WG-ENV be involved closely with ECMWF in drafting background papers for making a case for the GAS. • Interactions with other stakeholders: ECMWF, EUMETSAT, DLR, EEA, …. • Stimulating the preparation of a COST Action for complementing GEMS and PROMOTE activities towards a European Network of AQFISs (ENAQFIS).

4. GMES Status • GMES (Global Monitoring for Environment and Security) is an ESA-ECinitiative and was launched in 1998; • 2005: for practical reasons GMES Programme Office (GPO) concluded that only a few initial services can be launched as a start • Three “pilot services” were selected and “fast-tracked”: • Land Monitoring • Marine (Core) Services • Emergency Response • Gradually, following these 3 fast-track pilot services, further services shall be implemented, based on user´s needs as identified and acknowledged by Member States and by the EC. • EC R&D FP7 will provide funding for GMES. • June 2005, GMES Advisory Council (GAC): several delegations desired to start looking into the possibility of an atmosphere-related service.

5. GMES Atmosphere Services (GAS) • There is strong interest within the environmental and meteorological communities to address such a service. • Preparation of an operational transition of GEMS in 2009 • Scoping paper (May 2006) to build a case that “fully operational services” could be implemented by 2008-09 • Sept. 2006; GAC: Workshop to be held in Dec. 2006 involving relevant stake-holders. • Preparation of an orientation paper for the workshop. • Building on conclusions of Workshop => Implementation of respective operational services will then be prepared => pilot GAS in 2009.

6. Questions & Issues • What shall be the scope of GAS ? • O3, Surface UV , Air Quality, Global & Regional Monitoring of Greenhouse Gases, Reactive Gases and Aerosols • Find consensus on what the operational services can and shall be ? • To be based on a Core Service architecture to produce basic global to European data sets. • To feed a set of Downstream Services providing specific information at regional to local levels. • Initially a subset of these services will constitute the GAS (should start their operational delivery by 2009) and from then onwards should be gradually complemented by additional services. • Involvement & coordination of relevant players: EEA, ECMWF, GEMS, PROMOTE, ESA, O3-SAF, CM-SAF, NEAs, NMSs (WG-ENV), ….

7. AQFIS: Air Quality Forecasting & Information System • Acquiring observational data (met+chem); • Processing and assimilating data into useful inputs/fields; • Forecasting the evolution of the dynamical and chemical state of the atmosphere (incl. emissions); • Post-processing and assessing models’ outputs; • Exchanging, disseminating, and archiving shared data, metadata, and products; • Monitoring the performance against the defined requirements and intended benefits (mainly from users).

9. Motivation • Legislation: to inform the public on AQ throughout the territory of MSs • forecasting the AQ and exceedances of limit and target values, • assess possible measures to abate exceedances using modelling tools • Exists today: various national systems in terms of model tools, monitoring data and institutional arrangements • EEA: data compilation for annual assessment through NRCs, near-real-time “Ozone on the Web” • NMSs: weather data and modelling, development of tools and models, sometimes AQ forecast • NEAs: dissemination of AQ information. Often AQ monitoring, sometimes AQ forecasts • Extra complexity: • AQ is an essentially trans-boundary phenomenon  limitation to a national approaches • forecasting the AQ is more difficult and less accurate than e.g. weather prediction  single-model forecasts are uncertain

10. Motivation for ENAQFIS • Today: patchwork of players: national systems in terms of model tools, monitoring data and institutional arrangements • EEA/EIONET: coordination, AQ data exchange, compilation • NMSs: weather data and modelling, development of tools and models. Infra. Data assimilation; Sometimes AQ forecast • NEAs: dissemination of AQ information. Often AQ monitoring, sometimes AQ forecasts • Legislation: inform the public on AQ throughout European MSs • Forecasting the AQ and exceedances of limit and target values, • Assess possible measures to abate exceedances using modelling tools • Extra complexity: • AQ is an essentially trans-boundary phenomenon: limitations from national approaches, ongoing international projects (GEMS, PROMOTE, SAFs, • Forecasting AQ is more difficult and less accurate than e.g. weather prediction  single-model forecasts are uncertain.

11. NETWORKING national AQFIS-systems • Existence of several National AQFIS with differing capacities, modalities, protocols and scientific bases ! => Need of: • a European-wide “network of systems”, bringing together all players in the field and allowing for near-real-time (NRT) interactions and data flows, finally leading to an operational CW forecasting network • Enhanced and structured dialogue, collaboration between the main actors involved. COST is a suitable neutral forum for the dialogue and for developing the basis of a chemical-weather forecasting “system of systems” in Europe.

12. COST Action Objectives To setup a forum for benchmarking, harmonising and developing approaches and practices for chemical weather forecasting network and near-real-time information systems in Europe. • Identify needs for the optimisation and harmonization of exchange of AQ data & integration of modelling systems; • Find out the gaps of existing knowledge and practices; • Review the potential for and means of multi-model ensemble and chemical data assimilation; • QA/QC criteria for CW forecasting systems; • Assess visualisation and dissemination platforms, arrangements, formats and protocols; • Build up on current systems, enhance cooperation and coordination between providers, operators, and users for improving the science and application of CW forecasting; • Establish and/or strengthen links with similar ongoing national and international activities and dedicated projects

16. Scientific Programme Addressing the issues and barriers for the inter-operability of the various systems (various models, data storing, resolution,…). Towards agreeing on formats, standards and protocols for data and model result transfer and exchange. • WP1 . Exchange of AQ forecasts and input data: Requirements on data exchange frequency, formats, existing infras. Combining forecast data and NRT observations in a single system. Provisions for quality checks. • WP2 . Multi-scale forecasting, multi-model ensemble, boundary data Multi-model AQ assessments and forecasting. QA/QC issues. Ensemble. Feasibility of emission scenarios (short term abatement). Multi-scale CW forecast and assessment • WP3 . Dissemination and visualisation: Dissemination of AQ information to users. What to display, harmonization possibilities: separate pollutants vs. AQ index. Inventory of national systems, other activities and organisations. Cross-cutting activity: coordinate with other organizations (EEA, WMO, EUMETNET/WG-ENV, etc.) and ongoing activities (GEMS, PROMOTE).
